• How to convert ffmpeg command to ffmpeg-python

  1er décembre 2020, par Retro Pie

  Hello and thanks for reading.

  


  I have the following command : ffmpeg -i tmp.mp4 -loop 1 -i mask.png -filter_complex "[0:v]split [a][b];[a]transpose=1,crop=720:888:0:196,scale=876:1080,setdar=876/1080 [crop];[b]transpose=1,crop=720:888:0:196,scale=1920:1080,setdar=16/9,avgblur=76 [back];[1:v]alphaextract [mask];[crop][mask]alphamerge [masked];[back][masked]overlay=522:0" "out.mp4

  


  And I would like to convert it to ffmpeg-python syntax. So far I was able to come up with the bellow, but it far from ready :

  


  overlay_file = ffmpeg.input(mask)
(
ffmpeg
.input(tmp).split()
.overlay(overlay_file.hflip())
.alphaextract(),
.alphamerge(),
.output('out.mp4')
.run()
)


  


  Any help will be appreciated.
