  • 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'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 ?

    I’m trying to decode mp3 to wav using ffmpeg :

    import alsaaudio
    
import wave
    
from subprocess import Popen, PIPE
    

    
with open('filename.mp3', 'rb') as infile:
    
    p=Popen(['ffmpeg', '-i', '-', '-f', 'wav', '-'], stdin=infile, stdout=PIPE)
    
    ...

    Next i want redirect data from p.stdout.read() to wave.open(file, r) to use readframes(n) and other methods. But i cannot because ’file’ in wave.open(file,’r’) can be only name of file or an open file pointer.

        ...
    
    file = wave.open(p.stdout.read(),'r')
    
    card='default'
    
    device=alsaaudio.PCM(card=card)
    
    device.setchannels(file.getnchannels())
    
    device.setrate(file.getframerate())
    
    device.setformat(alsaaudio.PCM_FORMAT_S16_LE)
    
    device.setsetperiodsize(320)
    
    data = file.readframes(320)
    
    while data:
    
        device.write(data)
    
        data = file.readframes(320)

    I got :

    TypeError: file() argument 1 must be encoded string without NULL bytes, not str

    So is it possible to handle data from p.stdout.read() by wave.open() ?
    Making temporary .wav file isn’t solution.

    Sorry for my english.
    Thanks.

  • ffmpeg how to convert pgs subtitles to srt

    20 mai 2015, par 8ofspades

    I’m having an issue with extracting subtitles from ffmpeg 2.6.2. I have an mkv file with 6 subtitle streams, and I would like to generate srt files for all of them. My ffprobe output for the streams is below.

        Stream #0:0(eng): Video: h264 (High), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 1k tbn, 59.94 tbc (default)
    
Stream #0:1(ita): Audio: ac3, 48000 Hz, stereo, fltp, 448 kb/s (default)
    
Stream #0:2(ita): Audio: dts (DTS), 48000 Hz, 5.0(side), fltp, 1536 kb/s
    
Metadata:
    
  title           : Italian
    
Stream #0:3(rus): Subtitle: subrip (default)
    
Metadata:
    
  title           : Russian
    
Stream #0:4(ita): Subtitle: hdmv_pgs_subtitle
    
Metadata:
    
  title           : Italian
    
Stream #0:5(eng): Subtitle: hdmv_pgs_subtitle
    
Metadata:
    
  title           : English
    
Stream #0:6(fre): Subtitle: hdmv_pgs_subtitle
    
Metadata:
    
  title           : French
    
Stream #0:7(ger): Subtitle: hdmv_pgs_subtitle
    
Metadata:
    
  title           : German
    
Stream #0:8(spa): Subtitle: hdmv_pgs_subtitle
    
Metadata:
    
  title           : Spanish

    The russian (subrip) subtitles work fine with

    ffmpeg -i input.mkv -c:s:0 copy sub_ru.srt

    however when I try and select and of the other (pgs) subtitle streams, it ignores the stream I selected and outputs the russian (stream 0:3) subtitles.

    I’m not sure if this an issue with my ffmpeg command or the fact that the other streams are pgs.

    Thanks
