I use it to inspect video frames by frames, particularly being able to go back one frame. VLC doesn't support it, this thread about the feature is hilarious https://forum.videolan.org/viewtopic.php?t=120627

i wonder why he's such an ass about it, and totally adamant that it's impossible when multiple players already do this fast. ego?

To do this well you need to keep the old frames around...or go back to the previous keyframe and re-render. That might be hard if your design is playback-optimized.

Just a ridiculous idea, could a reversed version of the video be kept around so that if you hit frame backwards it's frame forwards operation on the reversed video so you can show that frame, if you continue playback the head goes to the closest second of the forward video

This would require completely re-encoding the video or keeping all decoded frames around. This is what he referred to as the "unbounded memory" solutions.

That makes sense, thank you!
