  • Pipe ffmpeg to oggenc(2) with .NET

    - by acidzombie24
    I am trying to encode ogg files at -q 6/192k. ffmpeg doesnt seem to be listenting to my command ffmpeg -i blah -acodec vorbis -ab 192k -y out.ogg So i would like to use the recommended ogg encoder. It says the input must be wav or similar. I would like to pipe a wav from ffmpeg to ogg. However not only am i unsure if oggenc2 will accept input from stdin, i have no idea how to pipe one process to another inside of .net using the Process class.

  • What are some practical uses of the "new" modifier in C# with respect to hiding?

    - by Joel Etherton
    A co-worker and I were looking at the behavior of the new keyword in C# as it applies to the concept of hiding. From the documentation: Use the new modifier to explicitly hide a member inherited from a base class. To hide an inherited member, declare it in the derived class using the same name, and modify it with the new modifier. We've read the documentation, and we understand what it basically does and how it does it. What we couldn't really get a handle on is why you would need to do it in the first place. The modifier has been there since 2003, and we've both been working with .Net for longer than that and it's never come up. When would this behavior be necessary in a practical sense (e.g.: as applied to a business case)? Is this a feature that has outlived its usefulness or is what it does simply uncommon enough in what we do (specifically we do web forms and MVC applications and some small factor WinForms and WPF)? In trying this keyword out and playing with it we found some behaviors that it allows that seem a little hazardous if misused. This sounds a little open-ended, but we're looking for a specific use case that can be applied to a business application that finds this particular tool useful.

  • ClickOnce disallow publishing of Debug builds

    - by LnDCobra
    Is there anyway to disallow publishing Debug builds when publishing ClickOnce aplications using Visual Studio 2008? I know this was asked before, but i can't figure out how from the answer. THe Accepted answer for previous question was: One thing you can do is add a condition to the .csproj or .vbproj file that MSBuild will check when doing a build. The condition would check if a publish is occurring and check if the build is a debug build, then do something like run an external tool or otherwise interrupt the build process or cause it to fail. Could anyone elaborate on that answer or tell me where/or how I can add this condition. [Original Question][1] [1]: http://One thing you can do is add a condition to the .csproj or .vbproj file that MSBuild will check when doing a build.

  • Start multiple processes of a dll in delphi

    - by Tom
    I have a "ActiveX library" project created with Delphi 2007. The library interface return XML data based on input values. This is then used by a PHP script that displays the data on a web page. This works great! The problem is that i can only run one instance of the dll process on the server. However, for security reasons, each of my customer should be able to access their own process of the dll (because the dll is always connected to only one database). Also, because of the way the delphi code is built, it doesn't support multiple threads. (It's a 100 000+ lines project using lots of singleton classes) Is there a way of starting several instances of the same dll? Is there a better way of transferring XML data from delphi to PHP? Sorry for the longish question, any help is appreciated (ps. I know the delphi code should be refactored, but this would mean 6 months of "circular reference" -hell :)

  • Lightweight messaging (async invocations) in Java

    - by Sergey Mikhanov
    I am looking for lightweight messaging framework in Java. My task is to process events in a SEDA’s manner: I know that some stages of the processing could be completed quickly, and others not, and would like to decouple these stages of processing. Let’s say I have components A and B and processing engine (be this container or whatever else) invokes component A, which in turn invokes component B. I do not care if execution time of component B will be 2s, but I do care if execution time of component A is below 50ms, for example. Therefore, it seems most reasonable for component A to submit a message to B, which B will process at the desired time. I am aware of different JMS implementations and Apache ActiveMQ: they are too heavyweight for this. I searched for some lightweight messaging (with really basic features like messages serialization and simplest routing) to no avail. Do you have anything to recommend in this issue?

  • Speccing out new features

    - by christopher-mccann
    I am curious as to how other development teams spec out new features. The team I have just moved up to lead has no real specification process. I have just implemented a proper development process with CI, auto deployment and logging all bugs using Trac and I am now moving on to deal with changes. I have a list of about 20 changes to our product to have done over the next 2 months. Normally I would just spec out each change going into detail of what should be done but I am curious as to how other teams handle this. Any suggestions?

  • dvi generation: no bounding box

    - by Akshey
    Hi, I wrote a research paper in latex and generated pdf using kile. It worked perfectly well. Now conference people are asking for dvi file also. But Kile's quick build process does not give a dvi file, but its 'Latex' compile process does. So I tried to compile the document, and it gave errors for includegraphics saying figure not found. When I append the correct extensions to the image names, that errors stopped coming but new errors came "bounding box is missing". I added bounding box values and now DVI file is being generated. My questions are: I have tried giving very high and low bounding box values but there is no deformation in the PDF. Why? Can I generate a DVI without giving bounding box values? Thanks and regards, Akshey

  • Supporting multiple instances of a plugin DLL with global data

    - by Bruno De Fraine
    Context: I converted a legacy standalone engine into a plugin component for a composition tool. Technically, this means that I compiled the engine code base to a C DLL which I invoke from a .NET wrapper using P/Invoke; the wrapper implements an interface defined by the composition tool. This works quite well, but now I receive the request to load multiple instances of the engine, for different projects. Since the engine keeps the project data in a set of global variables, and since the DLL with the engine code base is loaded only once, loading multiple projects means that the project data is overwritten. I can see a number of solutions, but they all have some disadvantages: You can create multiple DLLs with the same code, which are seen as different DLLs by Windows, so their code is not shared. Probably this already works if you have multiple copies of the engine DLL with different names. However, the engine is invoked from the wrapper using DllImport attributes and I think the name of the engine DLL needs to be known when compiling the wrapper. Obviously, if I have to compile different versions of the wrapper for each project, this is quite cumbersome. The engine could run as a separate process. This means that the wrapper would launch a separate process for the engine when it loads a project, and it would use some form of IPC to communicate with this process. While this is a relatively clean solution, it requires some effort to get working, I don't now which IPC technology would be best to set-up this kind of construction. There may also be a significant overhead of the communication: the engine needs to frequently exchange arrays of floating-point numbers. The engine could be adapted to support multiple projects. This means that the global variables should be put into a project structure, and every reference to the globals should be converted to a corresponding reference that is relative to a particular project. There are about 20-30 global variables, but as you can imagine, these global variables are referenced from all over the code base, so this conversion would need to be done in some automatic manner. A related problem is that you should be able to reference the "current" project structure in all places, but passing this along as an extra argument in each and every function signature is also cumbersome. Does there exist a technique (in C) to consider the current call stack and find the nearest enclosing instance of a relevant data value there? Can the stackoverflow community give some advice on these (or other) solutions?

  • Is Akka a good solution for a concurrent pipeline/workflow problem?

    - by herpylderp
    Disclaimer: I am brand new to Akka and the concept of Actors/Event-Driven Architectures in general. I have to implement a fairly complex problem where users can configure a "concurrent pipeline": Pipeline: consists of 1+ Stages; all Stages execute sequentially Stage: consists of 1+ Tasks; all Tasks execute in parallel Task: essentially a Java Runnable As you can see above, a Task is a Runnable that does some unit of work. Tasks are organized into Stages, which execute their Tasks in parallel. Stages are organized into the Pipeline, which executes its Stages sequentially. Hence if a user specifies the following Pipeline: CrossTheRoadSafelyPipeline Stage 1: Look Left Task 1: Turn your head to the left and look for cars Task 2: Listen for cars Stage 2: Look right Task 1: Turn your head to the right and look for cars Task 2: Listen for cars Then, Stage 1 will execute, and then Stage 2 will execute. However, while each Stage is executing, it's individual Tasks are executing in parallel/at the same time. In reality Pipelines will become very complicated, and with hundreds of Stages, dozens of Tasks per Stage (again, executing at the same time). To implement this Pipeline I can only think of several solutions: ESB/Apache Camel Guava Event Bus Java 5 Concurrency Actors/Akka Camel doesn't seem right because its core competency is integration not synchrony and orchestration across worker threads. Guava is great, but this doesn't really feel like a subscriber/publisher-type of problem. And Java 5 Concurrency (ExecutorService, etc.) just feels too low-level and painful. So I ask: is Akka a strong candidate for this type of problem? If so, how? If not, then why, and what is a good candidate?

  • Problems with PHP System_Daemon and IMAP connection.

    - by mike
    I'm trying to create a PHP daemon that connects to an IMAP server and processes emails as they come in. I have it close to working, but the daemon keeps grabbing the original emails that it finds the first time the daemon is loaded. I believe the reason is because I'm opening the IMAP connection in the parent process. Example below: if ($imapConnection=imap_open($authhost,$user,$pass) or die()) { //start daemon while() { //Grab email headers $imapHeaders = imap_headers($imapConnection); $count = sizeof($imapHeaders) //loop the emails for($i = 1; $i <= $count, $i++) { //process the email //delete the email } System_Daemon::iterate(15); } } imap_close($imapConnection); I'd like to stay away from putting the IMAP connection within the loop. How can I keep the connection to the IMAP server outside of the loop and still get new emails?

  • Re processing emails on error from pop3 account

    - by Timmy O' Tool
    Hi! I have an application that read emails from a pop3 account. When I connect to the account I download all new emails and process body and attachments. If there is an error processing one of the emails I would like to download it again next time I connect to the account but since I only get new emails and the failed one was already downloaded I don't get it so I can try to process it again. I can do it this with any pop3 command or I have to store locally failed emails?

  • What are the correct steps to capture data with uploadify?

    - by Curtis
    Does anyone have a demo of using uploadify with additional fields and saving to database? The site's examples don't explain the process in depth and I am not familiar with jquery. I don't know why but I can't get my head around how too integrate the two. I have the demo working and I have my app which uses traditional php/html forms working. I need to conduct basic form collection with uploadify in the mix. Collect data and check data with feedback and then process into database and post back a confirmation. How do I feed information back to the uploadify form if there is a problem from the upload.php file? How do I access my data in the upload.php file? how do I redirect the upload page to a confirmation page after a succeeful upload?

  • How to know start and kill processes within Java code (or C or Python) on *nix

    - by recipriversexclusion
    I need to write a process controller module on Linux that handles tasks, which are each made up of multiple executables. The input to the controller is an XML file that contains the path to each executable and list of command line parameters to be passed to each. I need to implement the following functionality: Start each executable as an independent Be able to kill any of the created processes independent of the others In order to do (2), I think I need to capture the pid when I create a process, to issue a system kill command. I tried to get access to pid in Java but saw no easy way to do it. All my other logic (putting info about the tasks in DB, etc) is done in Java so I'd like to stick with that, but if there are solutions you can suggest in C, C++, or Python I'd appreciate those, too.

  • How to do steps of an API through CLI

    - by Dolphin
    I'm using Audiveris API to generate xml(MusicXML) file once the sheetmusic(e.g. pdf/img file) is being input (i.e. When I give the sheet music (pdf file) location, to generate the xml file out of it (in another location)). Audiveris has its own GUI to do this. But can I do this process of sheetmusic-to-xml without using their GUI, but only from the CLI? If so how may I approach it? And also if so - is there a possibility to make it work in CLI - using Java code (say to invoke steps for API to occur in the CLI using Java Code)? I managed to open the GUI by opening the jar file from CLI. But I need to know whether there's a possibility to carry out the sheetmusic(say pdf)-to-xml process without using their GUI, but only through CLI? Greatly appreciate any help or guidance Thanks in advance

  • Get CruiseControl to talk to github with the correct public key.

    - by Danny Lister
    Hi All, Has anybody installed git and ControlControl and got CruiseControl to pull from GitHub on a window 2003 server. I keep getting public key errors (access denied) - Which is good i suppose as that confirms git is talking to github. However what is not good is that I dont not know where to install the rsa keys so they will be picked up by the running process (git in the context of cc.net). Any help would save me a lot of hair! I have tried installing the keys into; c:\Program Files\Git.ssh Whereby running git bash and cd ~ take me to: c:\Program Files\Git Current error from CC.net is Error Message: ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: Permission denied (publickey). fatal: The remote end hung up unexpectedly .
