Our A/V sync is very broken for streams where we can’t keep up at all: e.g. 4K, we end up presenting frames at the wrong time, and showing a very low number of decoded frames.

If the skip to next keyframe logic was properly working, as it includes the number of skipped frames in the stat, it should always show the same number of decoded frames. But it doesn’t. By the end of my 30s playback, the video frames painter are about 15s behind audio.
