  • How to deal with cv::VideoCapture decode errors ?

    24 février 2016, par George Profenza

    I’m streaming H264 content from an IP camera using the VideoCapture from OpenCV (compiled with ffmpeg support).

    So far things work ok, but every once in a while I get decoding errors (from ffmpeg I presume) :

    [h264 @ 0x103006400] mb_type 137 in I slice too large at 26 10
    
[h264 @ 0x103006400] error while decoding MB 26 10
    
[h264 @ 0x103006400] negative number of zero coeffs at 25 5
    
[h264 @ 0x103006400] error while decoding MB 25 5
    
[h264 @ 0x103006400] cbp too large (421) at 35 13
    
[h264 @ 0x103006400] error while decoding MB 35 13
    
[h264 @ 0x103006400] mb_type 121 in P slice too large at 20 3
    
[h264 @ 0x103006400] error decoding MB 20 3

    These messages show up in the console. Is there any clean way to listen to these ? I’d like to skip processing the glitchy frames.

    Any hints/tips ?

  • Syncronising Video/audio with two different sources

    22 mai 2016, par Indy

    I have an issue with an very old film that I’m trying to recover. I have two source of the same film.

    Source 1 (from ffmeg -i) :

    Duration: 02:43:35.77, start: 0.000000, bitrate: 1342 kb/s

    Source 2 (from ffmeg -i) :

    What I would like is to take the audio from source 1 and video from source 2 and create a new file with them.

    I have tried changing the source 1 to 30 fps and then using its audio with source 2’s video but the audio ’fps’ is really after sync after sometime. Perhaps my approach is wrong.

    what’s the best way to take the audio from source 1 synced with source 2’s video ?

    Any help is appreciated. Thanks,
    Indy
