• Does anybody know how to concat on ffmpeg and python ? [closed]

  22 décembre 2023, par Jonas Harker

  I created a code on Python that supposedly concatenates two videos using Python to run an ffmpeg command through subprocess.
I get this error message :

  I hoped they would concat, but they did not.

  Masked Compound Inter Prediction

  The masked compound motion compensation has mask types separating a
  block into wedges at specific angles and offsets. The mask is used to
  weight pixels from the first and second predictors to obtain the final
  predictor. The weighting is smooth near the partition boundaries but
  becomes a selecton farther away.

  I'm building a video converter for someone. All I need to know is, When someone pastes in a URL to a video, how can I download that video to the server ? Anything here would be helpful.
