  • How to get the duration/bitrate of a H264 file with avconv/ffmpeg

    11 juillet 2016, par maximedupre

    Executing avprobe test.h264 outputs

    Input #0, h264, from 'test.h264':
    
  Duration: N/A, bitrate: N/A
    
    Stream #0.0: Video: h264 (High), yuv420p, 720x480, 25 fps, 25 tbn, 50 tbc

    Executing file test.h264 outputs

    test.h264: JVT NAL sequence, H.264 video @ L 30

    Note that the file isn’t damaged or corrupted, I can play it with no problem on VLC.

    Is there a way to get the duration and bitrate from a raw H264 file ? I read somewhere that it might be possible if I decode the file first, but I’m not sure how this can be done.

    Edit #1

    I’m the one creating the H264 file with a Python library called picamera.

    Edit #2

    Console output when running avconv -i test.h264 -f null -
