  • FFMPEG PNG sequence into mkv cause "inflate returned error -3" every 600-800 frames [closed]

    30 novembre 2023, par sergey9295

    I am new to ffmpeg. I try to use it for creating videos from png sequences. I have uncompressed pngs. All of them rgb24 format.

    


    But during encoding process I get inflate errors. I compared PNG and video frame by frame. And video have approximately 1 dupe frame every 600-800 frames instead of the ones that should be on that places. I tried another codecs, tried to clear png's EXIF(it made things even worse), made sure that memory was enough. Doesn't matter.

    


    The worst part is that this errors are pretty random. I encode one sequence 3 times and get 3 different sets of error-causing frames.

    


    FFMPEG was downloaded from official site.

    IMO the problem is zlib from libpng. But I don't have skills to recompile it with libspng that doesn't require zlib. Maybe there is a ffmpeg version without this error ?
