• FFMEPG - How to resolve 'Reinit context to WxH ... deprecated pixel format'

  30 juin 2022, par hi im Bacon

  I am using the pyav library to read and process video data and as I am reading through the videos I am getting lots (and lots) of the following output.

  


  I am creating the videos by segmenting either a much larger source file or RTSP/HTTP IP camera.

  


  I would love to understand what this output actually means, and what I can do to prevent its output

  


  ffmpeg creating videos :

  


  ffmpeg -y -i https://manifest.googlevideo.com/api/... -pix_fmt yuvj422p -c:v libx264 -an -vf scale='min(1280,iw)':'min(720,ih)':force_original_aspect_ratio=decrease -r 12 -vsync cfr -x264opts keyint=12:min-keyint=12 -f segment -segment_format matroska -segment_time 5 -initial_offset 1656497474.686672 -strftime 1 /tmp/tmp87cc1n2o/%Y-%m-%dT%H%M%S.mkv -loglevel error


  


  python :

  


  container = av.open(io.BytesIO(...))
for frame in container.decode(video=0):

  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 converting to .265 corrupts videos

  25 juin 2022, par Alfa

  I'm trying to convert and compress videos in React Native using FFmpegKit, what is strange is it is very slow regardless of the preset I use, Also, no matter how big the input video is, it always produces a video less than 1MB that is corrupt.
This is my first time using FFmpeg, I'm using it due to the lack of good video compressing libraries on React Native.

  


  My command looks like this :

  


  const getFFmpegCommand = (input: string, output: string) => {
  const scale = `"scale='if(gte(iw,ih),min(720,iw),-2):if(lt(iw,ih),min(720,ih),-2)'"`;
  const preset = '-preset veryfast ';
  const ffmpegCommand = `-i ${input} -y -crf 28 -vf ${scale} ${preset} -c:v libx265 ${output}`;
  return ffmpegCommand;
};


  


  This is my log output
