• creating videos with ffmpeg/MoviePy - returns error

  9 avril 2021, par danielsulux

  After using moviepy, it has been shown to have worked, everything is updated. I see no issue with the code, but somehow it returns error.

  


  raise IOError(("MoviePy error: failed to read the duration of file %s.\n"


  


  OSError : MoviePy error : failed to read the duration of file ./Memes_APR_2021_V8/2546583872676854731-pubity-750-1333.mp4.

  What it is doing is :
Grabbing videos from my library and making a video with them
thats it...

  


  How do I get this to work ?
