  • Python : mp3 to wave.open(f,'r') through ffmpeg pipe

    7 avril 2015, par user2754098

    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.

  • 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 ?

    So I put in ffmpeg and got a 403 forbidden error

    


    [https @ 0x55c2fae84d80] HTTP error 403 Forbidden
[crypto @ 0x55c2fb11ebc0] Unable to open resource: https://contentplayer.website.com/video/4vqnGjj0L3/hls/540/segment-1.ts
[hls @ 0x55c2fae807c0] Failed to open segment 1 of playlist 0
...


    


    I thought it could be because of some missing http header, so I copied the cURL command from devtools. (I copied from the request of a segment, in which I had the cloudfront authorization key)

    


    I took all the headers from cURL and added them to ffmpeg.

    


    ffmpeg -allowed_extensions ALL -headers 'User-Agent: ...'
-headers 'Accept: */*' 
-headers 'Accept-Language: ...' 
-headers 'Referer: https://player....com/' 
-headers 'Origin: https://player....com' 
-headers 'Connection: keep-alive'
-headers 'Cookie: CloudFront-Policy=..; CloudFront-Signature=...; CloudFront-Key-Pair-Id=..; hotid=..; hmVlcIntegration=..' -headers 'Pragma: no-cache' -headers 'Cache-Control: no-cache' -headers 'TE: Trailers' 
-protocol_whitelist file,crypto,https,tcp,tls -i esse.m3u8  -map 0 -c copy output.mkv  -i link.m3u8  -map 0 -c copy output.mkv


    


    However, I still receive the 403 forbidden error. When I execute the cURL command it downloads the contents of the fragment. My hypothesis was that because it is about HTTP2 the headers were not sent after the first connection, but all the important headers were added.
other ways of doing this process are also welcome
