  28 novembre 2022, par Raman

  I'm trying to install development version of CVAT according to official instruction but struggling at the step of requirements.txt applying :

  I have already tried suggested fixes, but no luck :
https://github.com/openvinotoolkit/cvat/issues/4406

  


  Environment :

  


  

  • MacBook Pro (Intel x64)

  


  • macOS Monterey (Version 12.4)

  


  • (pyenv) Python 3.9.10

  


  


  What other options could be applied to fix it ?

  


• 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 ?
