• 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 ?

• Duplicate a signal with FFmpeg library [on hold]

  22 septembre 2016, par Meugiwara

  I’m using the FFmpeg library to develop a program in C/C++. At this time, my aim is to duplicate the signal when I open an audio file. My scheme is the next : read an audio file, transform the stereo signal in mono signal and duplicate this mono signal to get two mono signal exactly the same.

  I watched in the Doxygen documentation on the official website, but I don’t find something interesting. Do someone know a good way to do this ?
