Automated installation script of MediaSPIP

25 avril 2011, par kent1

To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.
The code of this (...)

Program hangs while using ffprobe on file with teletext subtitles

6 août 2012, par Jon

Having a problem running ffprobe on an MKV file that contains teletext subtitles. Code is in a C# library and works fine for other MKV files.

Running the latest :

ffprobe -v



ffprobe version N-42347-g299387e Copyright (c) 2007-2012 the FFmpeg developers

  built on Jul  8 2012 15:44:54 with gcc 4.7.1

Code :

string args = string.Format("-show_format -show_streams \"{0}\"", FileName);



Process p = new Process();

p.StartInfo = new ProcessStartInfo(FFPROBE_PATH);

p.StartInfo.Arguments = args;

p.StartInfo.CreateNoWindow = true;

p.StartInfo.RedirectStandardOutput = true;

p.StartInfo.RedirectStandardError = true;

p.StartInfo.UseShellExecute = false;

p.StartInfo.WorkingDirectory = System.IO.Directory.GetCurrentDirectory();

p.Start();



while (!p.HasExited)

{

    System.Threading.Thread.Sleep(100);

}



string output = p.StandardOutput.ReadToEnd().Replace("\r\n", "\n");

The filename has a UNC path - tried using the FileName parameter but got an error, hence passing the filename via the arguments.

If I run the following commandline :

ffprobe -show_format -show_streams "\192.168.10.1\content\Breakfast At Tiffany's sample preview.mkv"

I get the following output (note the errors - "Unsupported codec with id ...") :

ffprobe -show_format -show_streams "\\192.168.10.1\content\Breakfast At Tiffany&#39;s sample preview.mkv"

My problem is, the process appears to hang. I took out the 'CreateNoWindow' option and, of course, I get a big blank window onscreen that normally just flashs by on a normal file. With the teletext subtitle file however, it persists. If I manually close it, the program continues and I seem to get the output I want.

So my question is, how can I debug this further, to find out why this is hanging and how to handle the error (or simply ignore it) and continue ?

Full HD video converted to FLV, slow playback in browser

12 février 2012, par Boyan Georgiev

I rendered a full HD video using Adobe AfterEffects CS5 in mp4 format. It plays just fine. I've got this video app to which I fed the mp4 file. The video app converts the mp4 to flv format and makes the video available via a web page. I've downloaded the resulting flv file to my local PC - it plays just fine in my VLC player. But, the problem is I'm getting awful playback inside my browser.

I've made sure the issue is not bandwidth related.
Both original mp4 file, and ffmpeg-converted FLV file, play perfectly using VLC player.
I've tested the FLV file with two players - Agryia FLV Player Elite and JW Player. Both players play the video awfully - really slow and very choppy.

Here's my ffmpeg -i myflvfile.flv :
`

Seems stream 0 codec frame rate differs from container frame rate: 119.88 (120000/1001) -> 59.92 (719/12)

Can any one point me in the right direction here ? Why is playback perfect with VLC player of both the mp4 and the flv file on my local PC, yet in my browser, using two different players, the playback is so bad ?

PS Here's my convert command :
