  UserWarning: x bytes wanted but 0 bytes read at frame index y (out of a total z frames), at time q sec. Using the last valid frame instead - Wiz Newest 'ffmpeg' Questions - Stack Overflow
  I have a script which subclips a larger video and then stitches needed parts together using concatenate and write video file in moviepy. But the problem is everytime i run the script i get the video but the audio is off sync, usually the audio starts normally, but over time becomes delayed. I suspect it is because i want to concatenate around 220 smaller mp4 videos into one big mp4 video, but every smaller clips receives the error:'UserWarning: In file test.mp4, 1555200 bytes wanted but 0 bytes read at frame index y (out of a total y+1 frames), at time x sec.

  How to add a time limit for ffmpeg multiple outputting download? [closed] - Nycelia Newest 'ffmpeg' Questions - Stack Overflow
  I've been trying to get multiple outputs with different duration of segments from a playlist url using ffmpeg. Example: 120 seconds of a live stream. One output must download 8 times 15 seconds segments. Other output must download 4 times 30 seconds segments. Both outputs will have the same content, but with different durations. It works fine when I use a single output, but with 2 outputs, it's not limited to 120 seconds. Instead it just keeps downloading. Note: I know I could get a single output and divide it into segments later, but I need this approach. ffmpeg -t 120 (...)
