  TypeError: must be real number, not NoneType.


  


  It used was to run but I don't remember if I might have updated numpy, ffmpeg, or any thing else that is now causing the error. I have tried the code on python 3.10 and 3.11 and get the same error in both. I was previously running it on python 3.10.

• sws_scale performance comparison to media players real time resize

  14 juillet 2018, par Andrey Katkov

  While playing 4K video user can resize players window - and result image will be scaled smoothly in run time.

  On the other hand - program written with libav which reads 4k video file frame by frame and scale it down with sws_scale function do it less effective : it took more time then video duration to resize it.

  Why is it so ? Maybe because player fps is less and some frames are skipped - but video still looks smooth ?

  Use fast HEX search in real time mode

  In good quality mode motion search, the best matches are normally
  found after searching in a large area. In real time mode, to make
  encoding fast, a center-biased fast HEX search is used, which
  converges quickly most of the time. A 4-point diamond search is
  also carried out as the following refining search, which gives more
  precise results, and maintains good motion search quality.

  At speed 5, the borg test on rtc set showed an overall PSNR loss of
  0.936%. The encoding speed gain is 4% - 5%.
