Give input to ffmpeg using named pipes

1er septembre 2012, par Akilan

I have a C program which generates a series of images and I wanted to make them into a video which should be streamed in real time or stored in a file. While reading up ffmpeg documentation I came across repeatedly that ffmpeg can take input from named pipes.

My question is in what format should the files given into the pipe should be and how to input the files into the pipe.

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 ?

undefined reference to `__stack_chk_guard'

20 décembre 2011, par moose

I'm trying to debug the ffmpeg (0.8.7) on x86 Windows OS.
When I run configure with the -fstack-protector-all and -fstack-check I get this in config.log :

gcc -mms-bitfields -fstack-protector-all -fstack-check -I/home/moose/x264 -c -o /tmp/ffconf.AZMYgppf.o /tmp/ffconf.NLPWVejs.c

C compiler test failed.

Where did I fail ?

EDIT :
I can't answer my own question, so I'll add the comment here :

Solved.. I had to link it against the libssp.a
However, there is no change with these two swiches (-fstack-protector-all and -fstack-check ) at all :-(
