  • Why won't this script accept any arguments?

    - by Nate Wagar
    I'm trying to write an SVN post-commit hook and, strangely, am getting hung up on what should be the easiest part. The Script: set REPO="$1" set REV="$2" set SVNBIN="/opt/CollabNet_Subversion/bin/" set SSHBIN="/usr/bin/ssh" set HOST="staging.domain.net" set timeout=30 set USERNAME="svn-usr" set E_NO_CONNECT=2 set E_WRONG_PASS=3 set E_UNKOWN=25 set CHANGED=`"$SVNBIN"svnlook changed --revision $REV $REPOS` echo "Here are changes: $CHANGED" >> /var/svn/repos/www/logs/testing echo "Command: $0; Repo: $REPO; Rev: $REV; Total: $#" >> /var/svn/repos/www/logs/testing set PROJECT "" Yet when I call it, it doesn't seem to be seeing the arguments I pass to it: /var/svn/repos/www/logs> sudo ../hooks/post-commit /var/svn/repos/www 33 svnlook: missing argument: --revision Type 'svnlook help' for usage. /var/svn/repos/www/logs> cat testing Here are changes: Command: ../hooks/post-commit; Repo: ; Rev: ; Total: 1 This is on a Solaris 10 SPARC box. I'm a bit of a script newbie, but shouldn't this be really easy??

  • Problem with Windows Service and network printers.

    - by Mohammadreza
    I have a Windows Service application that every now and then should print some documents. As far as I know, to print those documents, my service must be run with a user account other than Local Service or Network Service. So i have created a user account and added that to the Administrators group and ran the service with it. With locally installed printers, I don't have any problems because those printers are automatically installed for all accounts. To be able to print with the network printers, I have created another application that syncs the installed printers of the currently logged in user with the user account that my service uses with the rundll32.exe printui.dll,PrintUIEntry command. In Vista and Windows7 I don't have any problems with the syncing of the printers because every time that a printer should be installed the authentication window will open and it asks for the appropriate user account to install that printer (The service user account is not created on the network printers computers) but in XP a find dialog with the "Connecting to {printername}" caption will appear and stops responding, or sometimes it installs the printer but every time service tries to print, a Win32Exception with "A StartDocPrinter call was not issued" message will throw and in the user account that runs the sync application a duplicate printer will be shown and I couldn't delete those printers unless with force (using registry). Am I doing the right thing for printing documents with Windows Services at all? If yes, how can I solve the above-mentioned problem? And if not, what the heck should I do? Thanks.

  • Finding a shared HDD attached to the network from my F-13 machine

    - by Ramy
    Sorry for the slew of n00bie questions, but here is one more. I recently partitioned my 1.5TB harddrive according to this question I then bought this to attach the harddrive to my network. The problem is, how do I navigate to the hard drive to move files over the network to the HDD. should this be moved to serverfault? update: the disk isn't even showing up when i call "fdisk -l" (as root). How can I mount it if I can't even find it?

  • Using modem for sending voice recording

    - by ircmaxell
    I've got an interesting one for you. I've been going over my server monitoring and notification systems (Nagios based), and realized that if our internet connection goes down, there's no way for it to notify me. I already have a modem listening (Via CentOS 5) on a spare POTS line so that I can dial-in in case our internet goes down. I was wondering if I could come up with a script (Shell, Python, etc) that can dial out and play a recorded message (wave file I'm guessing) when it's picked up. I know Windows supports voice calls over a voice modem, I was wondering if a solution existed for Linux... I know asterisk can probably do it, but isn't that overkill (A full blown VOIP system just for a notification mechanism that will hopefully never be used)? And wouldn't it interfere with the modem's primary function as a backup network interface (PPP spawned via mgetty)? I've done some searching, and haven't really come up with much. I know how to dial out from the command line, but only as a modem (not as voice). Worst case, I could set it up to dial out as a modem, and then just realize that if I get a call with modem sounds from that number that it's the notification... Any insight would be appreciated...

  • Microsoft Word 2007 restarts the installer upon exiting on Windows XP

    - by leeand00
    A user complained that they were having issues with MS Office 2007, and that the installation / configuration dialog kept appearing. I already tried uninstalling Office 2007 and I ended up needing to use the Microsoft Fix It package to uninstall it, since using the control panel failed. I close Microsoft Word. The Installer for Microsoft Office inexplicably opens. I then get a dialog that says I need to reboot. So I restart... Start Microsoft Word, Word starts up, and everything appears to be fine. I close word, and nothing much happens this is on the administrator account. I think everything is fixed so I call the user over to come try their account out. We login as the user, and the user tries to open a document in Word. The Configuration Progress Window reappears. It runs...and then Word appears. I close it and it appears to work, no window. I open it again and the Configuration Progress window appears yet again... Then Word opens up again, if I exit out and open up again I get the same Configuration Progress window. I have no idea what is causing the Configuration Progress Window to come up.. Update: I attempted to install two updates: Update for Microsoft Office Outlook 2007 Junk Email Filter (KB2687400) Update for the 2007 Microsoft Office System (KB967642) Both of these updates failed. Update: I attempted to install KB967642 manually and it failed.

  • Apache process consumes too much CPU

    I have an ubuntu apache/php server running php doing appx 100 hits/sec and a PHP cron running in the background.

  • How can I set the CD audio volume in Linux?

    - by user1296362
    In Windows 7 Control Panel - Sound - Sound Properties window there's an slider for setting CD Audio volume: And it's pretty strange that I can't find corresponding one in generic Linux mixers: alsamixer or amixer. I connected a CD drive to try to set CD audio volume with cdcd (CD Player): $ cdcd setvol 0 Invalid volume It isn't actually an invalid volume, it is because ioctl() call fails. I found that out after searching and changing a bit the source code of this utility (in the libcdaudio): --- cdaudio.c.orig 2004-09-09 06:26:20.000000000 +0600 +++ cdaudio.c 2012-05-30 21:34:34.167915521 +0600 @@ -578,8 +578,10 @@ cdvol_data.CDVOLCTRL_BACK_RIGHT_SELECT = CDAUDIO_MAX_VOLUME; #endif - if(ioctl(cd_desc, CDAUDIO_SET_VOLUME, &cdvol) < 0) - return -1; + if(ioctl(cd_desc, CDAUDIO_SET_VOLUME, &cdvol) < 0) { + printf("*** cd_set_volume: ioctl() returned error\n"); + return -1; + } return 0; } By the way cdcd's get volume command yields rather weird output: Left Right Front 1281734864 32767 Back 0 0 Also I tried aumix: $ aumix -c 0 But all with no success.

  • Redis as substitution for Memcache

    - by Boban P.
    We have distributed web app, and for now, as session handler, we use two separate instances of memcache in redundancy, so everything that is written in one memcache is also written in other. Memcache is fairly easy to install, use, and maintain but we have one problem: if one memcache fail, everything is fine, php comunicate with other instance which has all data (although, half of connections have a delay because they try to use failed one, wait a little, and then contact other memcache). When failed instance comes back to life again, it starts up empty. If established session request data from that instance, session fails, and user logs out, and that happens to half of users.So, we are thinking about to switch to redis for session handling, and maybe keep memcache for cache only. My questions are: If we setup redis instances as master-slave, and if master fails, can sentinel promote slave as new master and when old master comes back to life, will it stay as slave or not? Is redis call malloc at startup to allocate part of memory, like memcache or varnish, or it calls malloc for every key inserted? And what are pros and cons of that?

  • Loopback connection via PHP's getimage size crashes server (Magento's CMS)

    - by Alex
    We were able to trace down a problem that is crashing our NGINX server running Magento until the following point: Background info: Magento Backend has a CMS function with a WYSIWYG editor. This editor loads some pictures via a controller in magento (cms/directive). When we set the NGINX error_log level to info, we get the following lines (line break inserted for better readability): 2012/10/22 18:05:40 [info] 14105#0: *1 client closed prematurely connection, so upstream connection is closed too while sending request to upstream, client: XXXXXXXXX, server: test.local, request: "GET index.php/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL,,/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9024", host: "test.local" When checking the code in the debugger, the following call does never return (in ´Varien_Image_Adapter_Abstract::getMimeType()` # $this->_fileName is http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif` # $_SERVER['REQUEST_URI'] = http://test.local/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL list($this->_imageSrcWidth, $this->_imageSrcHeight, $this->_fileType, ) = getimagesize($this->_fileName); The filename requests is an URL to the same server which is requesting the script a link to a static .gif that is not existing. Sample URL: http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif When the above line executed, any subsequent request to the NGNIX server does not respond any more. After waiting for around 10 minutes, the NGINX server starts answering requests again. I tried to reproduce the error with a simple test script that only calls getimagesize() with the given URL - but this not crash. It simple leads to an exception saying that the URL could not be loaded (which is fine as the URL is wrong)

  • Shell not finding binary when attempting to execute it (it's _definitely_ there)

    - by eegg
    I have a specific set of binaries installed at: ~/.GutenMark/binary/<binaries...> These were previously working correctly, but for seemingly no reason when I attempt to execute them the shell claims not to find them: james@anubis:~/.GutenMark/binary$ ls -al ... -rwxr-xr-x 1 james james 2979036 2009-05-10 13:34 GUItenMark ... -rwxrwxrwx 1 james james 76952 2009-05-10 13:34 GutenMark ... -rwxr-xr-x 1 james james 10156 2009-05-10 13:34 GutenSplit ... james@anubis:~/.GutenMark/binary$ ./GutenMark bash: ./GutenMark: No such file or directory james@anubis:~/.GutenMark/binary$ I've tried to isolate the cause of this, with no success. The same happens with zsh, bash, and sh (all giving their appropriate "file not found" error -- this is definitely not a strange output from the binary itself). The same happens either as user james or as root. Nor is it directory specific; if I move the whole directory installation, or just a single binary, to anywhere else, the same happens when attempting to execute it. The same even happens when I put the directory in $PATH and just execute "GutenMark". It also happens when I execute it from a script (I've tried Python's commands module -- though this appears to just call sh). The problem appears to be specific to the binaries themselves, yet they appear to never actually get executed. Any ideas?

  • Specify default group and permissions for new files in a certain directory

    - by mislav
    I have a certain directory in which there is a project shared by multiple users. These users use SSH to gain access to this directory and modify/create files. This project should only be writeable to a certain group of users: lets call it "mygroup". During an SSH session, all files/directories created by the current user should by default be owned by group "mygroup" and have group-writeable permissions. I can solve the permissions problem with umask: $ cd project $ umask 002 $ touch test.txt File "test.txt" is now group-writeable, but still belongs to my default group ("mislav", same as my username) and not to "mygroup". I can chgrp recursively to set the desired group, but I wanted to know is there a way to set some group implicitly like umask changes default permissions during a session. This specific directory is a shared git repo with a working copy and I want git checkout and git reset operations to set the correct mask and group for new files created in the working copy. The OS is Ubuntu Linux. Update: a colleague suggests I should look into getfacl/setfacl of POSIX ACL but the solution below combined with umask 002 in the current session is good enough for me and is much more simple.

  • Can MS Services for Unix be deployed and accessed from a shared drive?

    - by Ian C.
    I'm interested in experimenting with replacing our dependency on MKS with MS' Sevices for Unix toolset. I was wondering if anyone has any experience with deploying SFU on a shared drive? We like to, wherever possible, host our dev tools on one central NAS and call to the NAS to access the tools instead of rolling stuff out to each and every desktop. I'm not interested in the NFS support or ActiveState Perl. Really, none of the daemon technology is required here. I'm looking for replacements for the coreutils/binutils stuff you find in Linux (and MKS on Windows): sed, awk, csh, bash, grep, ls, find -- the meat-and-potates command line apps that our build and test scripts are built around. If I limit the install to just the Interix GNU Components (and maybe the Remote Connectivity components) will is run nicely from a shared location? To head off some questions: Yes, I've looked at Cygwin. Unfortunately it's performance in our build and test environment is poor. It runs considerably slower than MKS and it's not a direct drop-in replacement for MKS (thanks to its internal pathing and limitations with commands like 'ps'), so it's a tougher sell. Yes, I'm looking at the MinGW offering in parallel to this.

  • What are the possible disadvantages of enabling the "data access" server option in sys.servers for t

    - by Corp. Hicks
    We plan to change the default server options of an SQL2k5 server instance by enabling data access. The reason is that we want to run "SELECT * FROM OPENQUERY(LOCALSERVER, '...')" -like statements on the server. What are the possible disadvantages of enabling server option "data access" (alias sys.servers.is_data_access_enabled) for the local server (sys.servers.server_id = 0)? (There must be a reason for MS setting this option to disabled by default...) EDIT: it turns out that I'm not the first person to ask this question: http://sqlblogcasts.com/blogs/piotr_rodak/archive/2009/11/22/data-access-setting-on-local-server.aspx "The DATA ACCESS server option is not very well documented in my opinion - the Books On Line say it is a property of linked servers. It doesn't mention at all that you actually can have it enabled on your local server to enable OPENQUERY calls. I noticed that when you disable DATA ACCESS on a linked server, you can't query any table located on it (I tested it on my loopback server) neither using OPENQUERY nor four-part naming convention. You can still call procedures (with four-part naming) that return rowsets. Well, the interesting question is why it is disabled by default on local server - I suppose to discourage users from using OPENQUERY against it." It also seems that the author of the post (Pjotr Rodak) is a Stack Overflow user :-)

  • Is Gmail Being Blocked by my ISP (wait till you read this)?

    - by James
    This is the strangest thing I have ever encountered. I have a desktop on which I cannot access Gmail and also youtube sign in (I believe since youtube is owned by google they both use the same sign in system). So okay, maybe my ISP is blocking these for some reason or maybe my firewall is, or maybe there is something wrong with my connectivity, right? NO. On other computers that uses the same connection via a wireless router I can access both gmail and youtube sign in just fine. On this computer which doesn't have a wireless card and so I have to connect via Ethernet cable (connected to a USB converter since the Ethernet port doesn't work anymore) I can access all sites and services including things like aol and hotmail. But only when it comes to gmail, do I get complete and utter throttling. I even turned off my AV ad Firewall momentarily and no luck. The gmail ages starts to load and by mid point it just stays there loading and loading and loading... never ends. I tried everything, I reset the modem and router multiple times. I reinstalled my operating system from a vista to a windows 7 hoping a complete reinstall would solve the issue, but no luck. So can anyone for the life of them figure out why this could be? And yes, I am going to call my ISP but not to solve this issue, but to cancel them. I want to upgrade to cabel from DSL anyway. I didn't mention my ISP because I'm not sure if that is within the rules (if it's okay some one let me know and I will). P.S. All this happened one day, before gmail was perfectly accessible in this computer. I can't remember anything special that happened on that day prior to this. The only thing I can think of is, my ISP or Google itself is blocking this computer based on it's mac address, but I don't know if that's even done. Additional info: PC: Windows 7 Ultimate 32 bit Connection Type: DSL Connecting Medium: Ethernet cable via USB converter

  • Can I recover a zpool after it's been exported, given that devices have not been reallocated?

    - by cali-spc
    I had a zpool we'll call 'testpool'. testpool had 3 devices included in it, and a single zfs called 'test'. I needed to move 'test' to a new, smaller pool. I wanted to name the new pool the same name 'testpool'. Basically did the following. zfs send testpool@backup > /tmp/test-dump zpool export -f testpool zpool create -f testpool newdevice zfs receive -F testpool < /tmp/test-dump Unfortunately I found out that the testpool@backup snapshot was the wrong snapshot. Too old. I have yet to reallocate the three devices that were in the OLD testpool. (None of these 3 devices are 'newdevice', they are a separate 3.) Is there any way I can recover data in those devices? I'm thinking since I named the new, smaller pool the same as the old zpool, I'm pretty much SOL. But if not, that would be nice to know. Edit: More info I did a 'zpool import' and got this. bash-3.00# zpool import pool: testpool id: 14781458723915654709 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: testpool ONLINE c5t8d0 ONLINE c5t9d0 ONLINE c5t10d0 ONLINE So I'm guessing I just need the syntax to import this zpool using its numeric identifier, while giving it a new name. S.

  • Dell Studio 1555 not starting up

    - by Abhishek
    This is a 3-year-old laptop. I never had a big problem with it until now. I updated Kubuntu the night before yesterday. And Firefox got updated to version 18 and a few other related packages got updated. Then I shut down the laptop and restarted it, but it failed to start. I could hear the fan and the hard disk and the optical disk drive initialize. And the power button also lighted up. But there was no video - no POST or BIOS menu. I even opened the laptop up to the point when only the motherboard was the only thing attached to the base cover. I took it to the technician this evening. He checked it casually, and said that it might be a motherboard problem and will cost quite a bit to fix. Though he was not sure and said that he will give me a call after confirming the problem. Has anyone else had the same problem? What was it and what was the fix?

  • MySQL Master - Master Broken

    - by Recc
    I've Inherited a Mysql master master system, I've noticed the second master (lets call it slave from now on as it's running on a 'slave' machine) stopped getting its db's updated. I saw that Master: Slave_IO_Running: Yes Slave_SQL_Running: Yes Slave: (with an error I truncated) Slave_IO_Running: Yes Slave_SQL_Running: No Last_Errno: 1062 Last_Error: Error 'Duplicate entry '3' for key 'PRIMARY'' on [...] I don't know what caused it to process considering we cant get duplicate there. What's important is to resume normal operations; Right now I've stop slave; on the Master and stop slave; on the Slave because I saw that if I change records on the Slave the changes Do Get Propagated to Master which is in active use. How do I: Force sync EVERYTHING from master to slave without affecting data on master? Then hopefully have slave pickup replication as usual? UPDATE OK I Tried deleting all tables on slave then it complained in that error section that the 'table' doesnt exist. So i made a no data dump of Master, and made sure I have only empty tables in Secondary (slave). I start slave; on slave BUT now it's complaining about bloody alter table statements for instance: Last_Errno: 1060 Last_Error: Error 'Duplicate column name [...] Query: 'ALTER TABLE [...] How to skip the fracking alter statements I just want to replicate the bloody data and be done with it, my tables have the lates changes already FFS and now its complaining about changes made after the replication seized weeks ago How do I reset the log or something? OUTSTANDING Why would this start happening? The "Secondary" is propagating to "Primary". "Primary" is not propagating to "Secondary". But any fixes I tried to do left it in the same state Yes-Yes Yes-No with same Last_Error. I think around that time the server was taken off the network, could that confuse MySQL in some way?

  • Unable to PPTP through NAT on Cisco 881

    - by MasterRoot24
    I'm trying to connect to a PPTP server which is sat behind a Cisco 881 NAT router. The server is running Ubuntu Server 12.04 and is running Poptop pptpd as the PPTP daemon listening for connections. As discussed in my other question, I'm trying to setup a Cisco 881 router to replace my old Linksys WAG320N. This same server and WAN connection worked fine with the WAG320N with no special configuration, other than allowing 1723 in through the firewall. On the Cisco 881, I'm using the newer ip nat enable or NAT NVI to setup static routes in through the firewall for the services running behind the router. My reason being that I can't run another copy of my live DNS domains internally with local IP addresses in. For the purposes of this question, though, I have rebuilt the router with ip nat inside/outside style NAT'ing, but this issue is still apparent. HTTP/SMTP/IMAP etc. all work ok from both the WAN and LAN interfaces of the router. I'm only having issues with SIP (see other question) and PPTP. My issue is that the GRE doesn't appear to be passing through NAT correctly and one end of the connection is not receiving GRE traffic when it should be, so the server hangs up the connection. Here's an example of /var/log/syslog with debug enabled in /etc/pptpd.conf: Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: MGR: Launching /usr/sbin/pptpctrl to handle client Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: local address = 192.168.1.50 Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: remote address = 192.168.1.51 Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: pppd options file = /etc/ppp/pptpd-options Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Client 82.132.248.216 control connection started Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Received PPTP Control Message (type: 1) Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: Made a START CTRL CONN RPLY packet Dec 11 21:06:30 <HOSTNAME> pptpd[22626]: CTRL: I wrote 156 bytes to the client.

When attempting a connection, I can see in show ip nat nvi translations that both a TCP translation on 1723 is setup and also a GRE translation is setup also. I appear to be able to see GRE related packets on the LAN that the server is on, so I am lead to believe that the server is sending(?) GRE packets, however running Wireshark on a client PC when attempting a connection shows absolutely no GRE packets. Whilst there are no configuration directives in my config posted above (that I can pin point) which would specifically block them, it would appear that the GRE packets are not being allowed in/out of the router's firewall, even though a NAT translation entry is setup to the server's LAN address. Would anyone be able to provide me with some help to ensure that GRE packets are not blocked by the router's firewall, so that this can be ruled out as a possible issue please?

  • Looking for a recommendation on measuring a high availability app that is using a CDN.

    - by T Reddy
    I work for a Fortune 500 company that struggles with accurately measuring performance and availability for high availability applications (i.e., apps that are up 99.5% with 5 seconds page to page navigation). We factor in both scheduled and unscheduled downtime to determine this availability number. However, we recently added a CDN into the mix, which kind of complicates our metrics a bit. The CDN now handles about 75% of our traffic, while sending the remainder to our own servers. We attempt to measure what we call a "true user experience" (i.e., our testing scripts emulate a typical user clicking through the application.) These monitoring scripts sit outside of our network, which means we're hitting the CDN about 75% of the time. Management has decided that we take the worst case scenario to measure availability. So if our origin servers are having problems, but yet the CDN is serving content just fine, we still take a hit on availability. The same is true the other way around. My thought is that as long as the "user experience" is successful, we should not unnecessarily punish ourselves. After all, a CDN is there to improve performance and availability! I'm just wondering if anyone has any knowledge of how other Fortune 500 companies calculate their availability numbers? I look at apple.com, for instance, of a storefront that uses a CDN that never seems to be down (unless there is about to be a major product announcement.) It would be great to have some hard, factual data because I don't believe that we need to unnecessarily hurt ourselves on these metrics. We are making business decisions based on these numbers. I can say, however, given that these metrics are visible to management, issues get addressed and resolved pretty fast (read: we cut through the red-tape pretty quick.) Unfortunately, as a developer, I don't want management to think that the application is up or down because some external factor (i.e., CDN) is influencing the numbers. Thoughts? (I mistakenly posted this question on StackOverflow, sorry in advance for the cross-post)

  • 530 5.7.1 Client was not authenticated Exchange 2010 for some computers within mask

    - by user1636309
    We have a classic problem with Client not Authenticated but with a specific twist: We have an Exchange 2010 cluster, let's say EX01 and EX02, the connection is always to smtp.acme.com, then it is switched through load balancer. We have an application server, call it APP01 There are clients connected to the APP01. There is a need for anonymous mail relay from both clients and APP01. The Anonymous Users setting of the Exchange is DISABLED, but the specific computers - APP01 and clients by the mask, let's say, 192.168.2.* - are enabled. For internal relay, a "Send Connector" is created, and then the above IP addresses are added for the connector to allow computers, servers, or any other device such as a copy machine to use the exchange server to relay email to recipients. The problem is that the relay works for APP01 and some clients, but not others (we get "Client not Authenticated") - all inside the same network and the same mask. This is basically what we do to test it outside of our application: http://smtp25.blogspot.sk/2009/04/530-571-client-was-not-authenticated.html So, I am looking for ideas: What can be the reason for such a strange behaviour? Where I can see the trace of what's going on at the Exchange side?

  • Cannot install CentOS 6.5 using UEFI usb boot

    - by Vaindil
    I am trying to dual-boot CentOS 6.5 on my desktop that is currently running Windows 8.1. I have two storage devices: an SSD that has my Windows installation, and an HDD that has all of my data. Both are formatted using GPT, and Windows boots using UEFI. I used the CentOS 6.5 live DVD (CentOS-6.5-x86_64-LiveDVD.iso) to create an EFI-bootable flash drive (it does boot properly in EFI mode). I receive an error, however, when CentOS is booting (error is below). I have a 6.4 boot DVD which boots as expected, but it does not boot in UEFI mode and therefore doesn't play nicely with my Windows installation (I have no way to access it, even using rEFInd or any other similar tools). What do I need to do to get the device to boot properly in UEFI mode? Kernel panic - not syncing: Attempted to kill init!

  • FFmpeg overlay two videos, one input with transparency

    - by Gian B.
    I am trying to create a karaoke from a CD+G file (converted to AVI using FFmpeg) and add a video as a background of the lyrics. Here's a screenshot of a the output from CD+G conversion, for simplicity let's call this lyrics.avi http://imgur.com/wUwHUhV Now a have this video.mp4 file that I'd like to put behind this lyrics.avi Here's a sample of what I'm trying to achieve http://imgur.com/8GuWXtQ I'm sure most of you are familiar with karaoke. I haven't used FFmpeg much and I'm not really sure if what I want to achieve is possible with FFmpeg. Is it possible to overlay two videos, and add a transparency to one of the videos? In this case the colour black? How can I set the offset time of the lyrics.avi? Here's the command the I've tried so far: ffmpeg -i video.mp4 -i lyrics.avi -filter_complex "nullsrc=size=854x480 [base]; [0:v] setpts=PTS-STARTPTS, scale=854x480 [upperleft]; [1:v] setpts=PTS-STARTPTS, scale=854x200 [bottomleft]; [base][upperleft] overlay=shortest=1 [tmp1]; [tmp1][bottomleft] overlay=shortest=1:y=280" -c:v libx264 -y karaoke.mp4
