  • How to load src in html5 Video tag from JavaScript?

    - by luis_laurent
    Here is the thing, I'm working with ASP.NET and I'm using this particular SignalR library to broadcast a video to my clients, but as far as I know I can not stream video because signalR is a messaging system and it is not intended to stream video, files or things like that. Now what I am trying to do is to split the video into buffers that is Base64-encoded into a string, then on the client I am decoding this string and I am trying to load it into the source of a Video tag. Here I show you what I am doing on the client: HTML Code: <video id="myVideo"> <source id="video_source"> </video> Javascript Code: //here somehow I am getting the string with the base64-encoded video function playVideo(message) { var myVideo = document.getElementById("myVideo"); var mySource = document.getElementById("video_source"); mySource.setAttribute("src", getEncodedVideoString("avi", message)); myVideo.load(); myVideo.play(); }; // here I am formatting and concatenating the string for my source attribute function getEncodedVideoString(type, file) { return 'data:video/' + type + ';base64,' + $.base64.decode(file); } Well as you can see, at the moment I'm facing a scenario a little weird, but I already have the video encoded on the client, now I just need to find out the way to reproduce that video. And here is when my question comes up, does any one has done something like this before, or you have any idea or suggestion to do that? P.S I am using this jquery-base64 library to decode my string

  • Need a set based solution to group rows

    - by KM
    I need to group a set of rows based on the Category column, and also limit the combined rows based on the SUM(Number) column to be less than or equal to the @Limit value. For each distinct Category column I need to identify "buckets" that are <=@limit. If the SUM(Number) of all the rows for a Category column are <=@Limit then there will be only 1 bucket for that Category value (like 'CCCC' in the sample data). However if the SUM(Number)@limit, then there will be multiple bucket rows for that Category value (like 'AAAA' in the sample data), and each bucket must be <=@Limit. There can be as many buckets as necessary. Also, look at Category value 'DDDD', its one row is greater than @Limit all by itself, and gets split into two rows in the result set. Given this simplified data: DECLARE @Detail table (DetailID int primary key, Category char(4), Number int) SET NOCOUNT ON INSERT @Detail VALUES ( 1, 'AAAA',100) INSERT @Detail VALUES ( 2, 'AAAA', 50) INSERT @Detail VALUES ( 3, 'AAAA',300) INSERT @Detail VALUES ( 4, 'AAAA',200) INSERT @Detail VALUES ( 5, 'BBBB',500) INSERT @Detail VALUES ( 6, 'CCCC',200) INSERT @Detail VALUES ( 7, 'CCCC',100) INSERT @Detail VALUES ( 8, 'CCCC', 50) INSERT @Detail VALUES ( 9, 'DDDD',800) INSERT @Detail VALUES (10, 'EEEE',100) SET NOCOUNT OFF DECLARE @Limit int SET @Limit=500 I need one of these result set: DetailID Bucket | DetailID Category Bucket -------- ------ | -------- -------- ------ 1 1 | 1 'AAAA' 1 2 1 | 2 'AAAA' 1 3 1 | 3 'AAAA' 1 4 2 | 4 'AAAA' 2 5 3 OR 5 'BBBB' 1 6 4 | 6 'CCCC' 1 7 4 | 7 'CCCC' 1 8 4 | 8 'CCCC' 1 9 5 | 9 'DDDD' 1 9 6 | 9 'DDDD' 2 10 7 | 10 'EEEE' 1

  • Using Gem Dependencies if a server is 2.0 instead of 2.1

    - by user548744
    At work for internal Rails applications, the server is running Rails 2.0.4 and Ruby 1.86. As far as I know, that's not going to change anytime soon and I have no control over it. I was going to try and test this out between a couple of computers and was curious if anyone knew what would happen. Being the server is on 2.0.4, I'd like to build Rails 2.3.5 applications for that server if at all possible. From what I understand so far, it won't be a problem if I freeze gems and upack dependancies. Does that sound right? Also, the internal work server has no gems beyond what Rails installs. What I'm wondering is, if I can successfully run a 2.3.5 application on the 2.0.4 server, can I also use extra gems and unpack those to use even though the server doesn't have them? I know that it was version 2.1 that introduced Gem Dependencies so would a 2.3.5 Rails app running on a 2.0.4 server be able to use required gems that are unpacked into an application? One of the worst things with this situation is even if the above stuff works, the server being on 1.86 would exclude me from using a lot of really cool gems that require Ruby 1.87 (like Formtastic). Thanks

  • Modifying html of dom element that was created after page loaded

    - by Ben321
    I have two separate AJAX calls. One that gets a list of items from a txt file and creates an HTML table out of them and one that talks to a database to find how much each item costs and then lists this in the corresponding table cell for each item (I know this may sound like a strange approach, but it's a good option in our case...). The issue is that the price is not getting written to the table since the table is created (or to be precise, the rows of the table are created) after the page loads. I'm not sure how to fix this. $(document).ready(function() { makeItemTable(); listPrices(); ... }); function makeItemTable() { $.ajax({ url: 'products.php', type: 'GET' }) .done(function(response) { $('.price-table > tbody').html(response); }) } function listPrices() { .ajax({ url: 'prices.php', type: 'GET' }) .done(function(response) { priceData = $.parseJSON(response); $('.price-table tr').each(function() { var item = $(this).find('td:nth-child(1)').text(); if (priceData[item]) { var price = priceData[item]; $(this).find('td:nth-child(2)').text(price); } }) }

  • Can I use a UINavigationController as the detail view of a UISplitViewController?

    - by B Sweigard
    I'm running into a problem with an iPad app where I would like to have UINavigationControllers in both of the views within a UISplitView. I've looked through other similar questions here, but most link to a tutorial online that doesn't completely solve the problem. Here's a 2-minute walkthrough to re-create the problem I'm having: Create a New Project in XCode, starting from the Split View-based Application template. Add the following NSLog statement as the first line within the DetailViewController's willHideViewController method: NSLog(@"toolbar: %@", toolbar); If you run the application now, the log will show that the DetailViewController's toolbar is alive and well. Now... Open MainWindow.xib and expand the SplitViewController. Drag a Navigation Controller from the library on top of the DetailViewController. Expand the new Navigation Controller and change the class of the UIViewController within to a DetailViewController. Ctrl-drag from the SplitViewController to the DetailViewController and assign it as the delegate. Save MainWindow.xib and run the app again. At this point, the detail view has a navigation bar and an empty toolbar. If you view the logs, you should find that the toolbar is null. Why is this? Am I missing some sort of connection in Interface Builder? Is the navigation bar the problem for some reason? Unlike the tutorial at http://www.cimgf.com/2010/05/24/fixing-the-uisplitviewcontroller-template/, I would like to keep both the navigation bar and the toolbar (preferably with the toolbar at the top when in portrait and not visible when in landscape), so that I still have a functional "Back" button when the iPad is in portrait orientation. Does anyone have any suggestions for fixing this problem? An example project with this sort of set-up would be ideal.

  • Not allow more than 5 digits after decimal. in on javascript "OnKeyUp"?

    - by James123
    I have a javascript code for textbox that will put commas on in digits like (11,23,233) mTextbox.Attributes.Add("OnKeyUp", "javascript:this.value=Comma(this.value);") function Comma(Num) { Num += ''; Num = Num.replace(',', ''); Num = Num.replace(',', ''); Num = Num.replace(',', ''); Num = Num.replace(',', ''); Num = Num.replace(',', ''); Num = Num.replace(',', ''); x = Num.split('.'); x1 = x[0]; x2 = x.length > 1 ? '.' + x[1] : ''; var rgx = /(\d+)(\d{3})/; while (rgx.test(x1)) x1 = x1.replace(rgx, '$1' + ',' + '$2'); return x1 + x2; } Now same here I need to restrict user to enter not morethan 5 digits after decimal (ex: Allow: 12,23,221.34323 Not Allow: 12,23,232.232423 I can change above javascript to work that?

  • Python: Parsing a colon delimited file with various counts of fields

    - by Mark
    I'm trying to parse a a few files with the following format in 'clientname'.txt hostname:comp1 time: Fri Jan 28 20:00:02 GMT 2011 ip:xxx.xxx.xx.xx fs:good:45 memory:bad:78 swap:good:34 Mail:good Each section is delimited by a : but where lines 0,2,6 have 2 fields... lines 1,3-5 have 3 or more fields. (A big issue I've had trouble with is the time: line, since 20:00:02 is really a time and not 3 separate fields. I have several files like this that I need to parse. There are many more lines in some of these files with multiple fields. ... for i in clients: if os.path.isfile(rpt_path + i + rpt_ext): # if the rpt exists then do this rpt = rpt_path + i + rpt_ext l_count = 0 for line in open(rpt, "r"): s_line = line.rstrip() part = s_line.split(':') print part l_count = l_count + 1 else: # else break break First I'm checking if the file exists first, if it does then open the file and parse it (eventually) As of now I'm just printing the output (print part) to make sure it's parsing right. Honestly, the only trouble I'm having at this point is the time: field. How can I treat that line specifically different than all the others? The time field is ALWAYS the 2nd line in all of my report files.

  • Mock implementations in C++

    - by forneo
    Hi guys, I need a mock implementation of a class - for testing purposes - and I'm wondering how I should best go about doing that. I can think of two general ways: Create an interface that contains all public functions of the class as pure virtual functions, then create a mock class by deriving from it. Mark all functions (well, at least all that are to be mocked) as virtual. I'm used to doing it the first way in Java, and it's quite common too (probably since they have a dedicated interface type). But I've hardly ever seen such interface-heavy designs in C++, thus I'm wondering. The second way will probably work, but I can't help but think of it as kind of ugly. Is anybody doing that? If I follow the first way, I need some naming assistance. I have an audio system that is responsible for loading sound files and playing the loaded tracks. I'm using OpenAL for that, thus I've called the interface "Audio" and the implementation "OpenALAudio". However, this implies that all OpenAL-specific code has to go into that class, which feels kind of limiting. An alternative would be to leave the class' name "Audio" and find a different one for the interface, e.g. "AudioInterface" or "IAudio". Which would you suggest, and why?

  • Flash video plays well, but time and time-remaining are out of sync.

    - by sparkyfied
    Hey guys, Could be a known issue, an issue with my code or an oversight on my part. I have created a video player in flash. I have got it playing progressive and streaming over rtmp/rtmpt so that is all fine. My only issue is that when the video's are playing, the time-codes for time played and time remaining are not synced. So, if my video is 20 secs long and 5 have been played, time played will be 5secs, time remaining will be 16secs until it updates about half a second later. So even though they are both being set with the same line of code, there are not changing at the same time. The time played changes, then a split second later the time remaining changes. Anyone got any idea what this could be. Maybe a miscalculation on my part. Maybe I need to round up or down the remaining time. How can I sync the two times. I understand this is probably an tough question to answer, I have done my best to explain it. Thanks in advance.

  • Best way to make sure I get all available options array/loop

    - by jaz872
    OK, here is my problem. I'm looking for the best way to loop through a bunch of options to make sure that I hit all available options. Some detail. I've created a feature that allows a client to build images that are basically other images layered on top of each other. These other images are split up into different groups. They have links on the side of the image that they can click to scroll through all the different images to view them. I'm now making an automated process that is going to run the function that changes the image when a user clicks one of the links. I need to make sure that every possible combo of the different images is hit during this process. So I have an array with the number of options for each group. The current array is [3, 9, 3, 3] My question is what is the best way to loop through this to make sure that all possible options will be shown? I apologize if this seems simple for someone out there, but I'm just having trouble wrapping my head around it. Hopefully if that person is out there, they can give a helping hand :)

  • How to optimize this MYSQL table?

    - by Lost_in_code
    This is for an upcoming project. I have two tables - first one keeps tracks of photos, and the second one keeps track of the photo's rank Photos: +-------+-----------+------------------+ | id | photo | current_rank | +-------+-----------+------------------+ | 1 | apple | 5 | | 2 | orange | 9 | +-------+-----------+------------------+ The photo rank keeps changing on a regular basis and this is the table that tracks it: Ranks: +-------+-----------+----------+-------------+ | id | photo_id | ranks | timestamp | +-------+-----------+----------+-------------+ | 1 | 1 | 8 | * | | 2 | 2 | 2 | * | | 3 | 1 | 3 | * | | 4 | 1 | 7 | * | | 5 | 1 | 5 | * | | 6 | 2 | 9 | * | +-------+-----------+----------+-------------+ * = current timestamp Every rank is tracked for reporting/analysis purpose. I talked to someone who has experience in this field and he told me that storing ranks like above is the way to go. But I'm not so sure yet. The problem here is data redundancy. There are going to be tens of thousands of photos. The photo rank changes on a hourly basis (many time within minutes) for recent photos but less frequently for older photos. At this rate the table will have millions of records within months. And since I do not have experience in working with large databases, this makes me a little nervous. I thought of this: Ranks: +-------+-----------+--------------------+ | id | photo_id | ranks | +-------+-----------+--------------------+ | 1 | 1 | 8:*,3:*,7:*,5:* | | 2 | 2 | 2:*,9:* | +-------+-----------+--------------------+ * = current timestamp That means some extra code in PHP to split the rank/time (and sorting) but that looks OK to me. Is this a correct way to optimize the table for performance? What would you recommend? Any suggestions would be great.

  • Timer not beginning from 00:00

    - by studentProgrammer
    I have a Game in which there is a timer involved. For each two minutes that passes a new round between different players begins. So, I have a text box starting from 00:00 and changes each second until it is equal to 02:00. Now, I want to save the state of the game in the middle of a round if the user closes the form. What I need to do is that upon loading, the textbox starts at the time that the user left the game the last time and continue up till 02:00 normally. How can I do this? This is what I have until now where Tournament is the Form public Tournament() { _timer = new System.Windows.Forms.Timer(); _timer.Interval = 1000; _timer.Tick += Timer_Tick; _myDateTime = DateTime.Now; newDate = new DateTime(); newDate = newDate.AddMinutes(2.00); _timer.Start(); InitializeComponent(); } void Timer_Tick(object sender, EventArgs e) { var diff = DateTime.Now.Subtract(_myDateTime); this.textBox1.Text = diff.ToString(@"mm\:ss"); DateTime dt = Convert.ToDateTime(diff.ToString()); if (newDate.Minute == dt.Minute) { _timer.Stop(); _myDateTime = DateTime.Now; displayPointsOrResults(); this.textBox1.Text = diff.ToString(@"mm\:ss"); } } In my LoadGame method: where timePassed is what I have written in the text box string[] splitted6 = timePassed.Split(':'); if (splitted6[0] == "00") { int remainingTime = 120 - Convert.ToInt32(splitted6[1]); DateTime time = DateTime.Now.Date; time = time.AddMinutes(remainingTime); _myDateTime = time; } else { int leftTime = Convert.ToInt32(splitted[0].Trim('0') + splitted[1]); int remainingTime = 120 - leftTime; DateTime time = DateTime.Now.Date; time = time.AddMinutes(remainingTime); _myDateTime = time; }

  • What db fits me?

    - by afvasd
    Dear Everyone I am currently using mysql. I am finding that my schema is getting incredibly complicated. I seek to find a new db that will suit my needs: Let's assume I am building a news aggregrator (which collects news from multiple website). I then run algorithms to determine if two news from different sites are actually referring to the same topic. I run this algorithm to cluster news together. The relationship is depicted below: cluster \--news1 \--word1 \--word2 \--news2 \--word3 \--news3 \--word1 \--word3 And then I will apply some magic and determine the importance of each word. Summing all the importance of each word gives me the importance of a news article. Summing the importance of each news article gives me the importance of a cluster. Note that above cluster there are also subgroups( like split by region etc), and categories (like sports, etc) which I have to determine the importance of that in a particular day per se. I have used views in the past to do so, but I realized that views are very slow. So i will normally do an insert into an actual table and index them for better performance. As you can see this leads to multiple tables derived like (cluster, importance), (news, importance), (words, importance) etc which can get pretty messy. Also the "importance" metric will change. It has become increasingly difficult to alter tables, update data (which I am using TRUNCATE TABLE) and then inserting from null. I am currently looking into something schemaless like Mongodb. I do not need distributedness. I would very much want something that is reasonably fast (which can be indexed) and something that is a lot more flexible that traditional RDMBS. Also, I need something that has some kind of ORM because I personally like ORM a lot. I am currently using sqlalchemy Please help!

  • Filter design for audio signal.

    - by beanyblue
    What I am trying to do is simple. I have a few .wav files. I want to remove noise and filter out specific frequencies. I don't have matlab and I intend to write my own code for all the filters. Right now, I have a way to read the .wav file and dump out the structure into a text file. My questions are the following: Can I directly apply the digital filters on this sampled data?{ ie, can I directly do a convolution between my input samples and h(n) for the filter function that i choose?). How do I choose the number of coefficients for the Window function? I have octave, so if someone can point me to anything that gives me some idea on how to process the .wav file using octave, that would be great too. I want to be able to filter out the frequency and then listen to the sound again. Is this possible with octave? I'm just a beginner with these kinds of things, so please bear with me if my questions are too naive. Any help will be great.

  • Fast and efficient way to read a space separated file of numbers into an array?

    - by John_Sheares
    I need a fast and efficient method to read a space separated file with numbers into an array. The files are formatted this way: 4 6 1 2 3 4 5 6 2 5 4 3 21111 101 3 5 6234 1 2 3 4 2 33434 4 5 6 The first row is the dimension of the array [rows columns]. The lines following contain the array data. The data may also be formatted without any newlines like this: 4 6 1 2 3 4 5 6 2 5 4 3 21111 101 3 5 6234 1 2 3 4 2 33434 4 5 6 I can read the first line and initialize an array with the row and column values. Then I need to fill the array with the data values. My first idea was to read the file line by line and use the split function. But the second format listed gives me pause, because the entire array data would be loaded into memory all at once. Some of these files are in the 100 of MBs. The second method would be to read the file in chunks and then parse them piece by piece. Maybe somebody else has a better a way of doing this?

  • Timed selector never performed

    - by sudo rm -rf
    I've added an observer for my method: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(closeViewAfterUpdating) name:@"labelUpdatedShouldReturn" object:nil]; Then my relevant methods: -(void)closeViewAfterUpdating; { NSLog(@"Part 1 called"); [self performSelector:@selector(closeViewAfterUpdating2) withObject:nil afterDelay:2.0]; } -(void)closeViewAfterUpdating2; { NSLog(@"Part 2 called"); [self dismissModalViewControllerAnimated:YES]; } The only reason why I've split this method into two parts is so that I can have a delay before the method is fired. The problem is, the second method is never called. My NSLog output shows Part 1 called, but it never fires part 2. Any ideas? EDIT: I'm calling the notification from a background thread, does that make a difference by any chance? Here's how I'm creating my background thread: [NSThread detachNewThreadSelector:@selector(getWeather) toTarget:self withObject:nil]; and in getWeather I have: [[NSNotificationCenter defaultCenter] postNotificationName:@"updateZipLabel" object:textfield.text]; Also, calling: [self performSelector:@selector(closeViewAfterUpdating2) withObject:nil]; does work. EDITx2: I fixed it. Just needed to post the notification in my main thread and it worked just fine.

  • Assigning a 2D array (of pointers) to a variable in an object for access in C++?

    - by MrMormon
    I'm sorry if I didn't pick a descriptive or concise name. A lot of questions sound similar, but I haven't been able to find what I'm looking for. What I want to do is store a 2D array of pointers somewhere and assign a variable in some object to that array to be able to access it. Here's some example code that has the same compile error I'm getting with a bigger project. #include <iostream> using namespace std; struct X{ float * b[8][8]; X(){ *(b[1][5]) = 1; cout << *(b[1][5]) << endl; } void Set(float * c[8][8]){ b = c; cout << *(b[1][5]) << endl; } }; main(){ float * a[8][8]; *(a[1][5]) = 2; X obj; obj.Set(a); } What I want to happen in this code is that an X object starts with its own 2D array, whose value pointed to by b[1][5] should be printed as "1". Then the main method's 2D array, a, is passed to the object's Set() method and assigned to its array variable. The value pointed to by b[1][5] should then be printed as "2". However, I can't figure out what type the Set() parameter, c, should be. I get error: incompatible types in assignment of ‘float* (*)[8]’ to ‘float* [8][8]’ when I try to compile. As for why I want to do this, I'm trying to use an array of pointers to objects, not floats, but it's the same error.

    I have some javascript code that saves a cookie. However, if after saving the cookie, the user opens a new tab, it appears that the cookie is not saved. The new tab is on the same domain. Here is my cookie setting/getting code: function setCookie(c_name,value,exdays) { var exdate=new Date(); exdate.setDate(exdate.getDate() + exdays); var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString()); document.cookie=c_name + "=" + c_value; } function getCookie(c_name) { var i,x,y,ARRcookies=document.cookie.split(";"); for (i=0;i<ARRcookies.length;i++) { x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("=")); y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1); x=x.replace(/^\s+|\s+$/g,""); if (x==c_name) { return unescape(y); } } } If some javascript calls setCookie('mycookie', 1) and then the user clicks on a link where the _target is set to _blank, the cookie does not load in the new tab. So getCookie('mycookie') will not return 1. What is the problem here?

  • Allowing user to type only one "."

    - by Tartar
    I am trying to implement a simple javascript-html calculator. What i want to do is,typing only one '.' by the user. How can i control this ? Here is the code that i tried. I can already find the number of '.' but i'am confused now also this replaceAll function is not replacing '.' with empty string. String.prototype.replaceAll = function(search, replace) { //if replace is null, return original string otherwise it will //replace search string with 'undefined'. if(!replace) return this; return this.replace(new RegExp('[' + search + ']', 'g'), replace); }; function calculate(){ var value = document.calculator.text.value; var valueArray = value.split(""); var arrayLenght = valueArray.length; var character = "."; var charCount = 0; for(i=0;i<arrayLenght;i++){ if (valueArray[i]===character) { charCount += 1; } } if(charCount>1){ var newValue=value.replaceAll(".",""); alert(newValue); } }

  • Google sheet dynamic WHERE clause for query() statement

    - by jason_cant_code
    I have a data table like so: a 1 a 2 b 3 b 4 c 5 c 6 c 7 I want to pull items out of this table by dynamically telling it what letters to pull. My current formula is: =query(A1:B7,"select * where A ='" & D1 & "'"). D1 being the cell I wish to modify to modify the query. I want to be able input into D1 -- a, a,b, a,b,c and have the query work. I know it would involve or statements in the query, but haven't figured out how to make the formula dynamic. I am looking for a general solution for this pattern: a -- A = 'a' a,b -- A = 'a' or A = 'b' a,b,c -- A = 'a' or A = 'b' or A='c' Or any other solution that solves the problem. Edit: So far I have =ArrayFormula(CONCATENATE("A='"&split(D3,",")&"' or ")) this gives A='a' or A='b' or A='c' or for a,b,c. can't figure out how to remove the last or.
