I’m using this command to extract keyframes from long videos (full movies).

ffmpeg -i data/full_videos/pleasantville_1998.mp4 -filter:v "select='gt(scene,0.1)',showinfo" -vsync 0 frames/%05d.jpg

For most videos this works fine, and it prints a line to stderr for each frame extracted, but sometimes it prints a couple of such lines and then errors with the output

I can’t see anything wrong with the failed videos when I watch them manually. From searching online, I’ve gained some understanding of how the encoding/decoding process works in general, but haven’t seen anything about this error.

If there’s some part of the video that’s corrupted, I’d like to just skip over the section around that part and take all possible keyframes from the other sections.
