The logic is continuously flipping between 25fps and 50fps and each time is re-initializing video.
The fix changes the order of fields used to determine framerate to give r_frame_rate a lower priority. r_frame_rate is described as the lowest possible frame rate. not the actual frame rate and was showing as 50. I think the description actually means highest possible frame rate, lowest frame interval
This fixes playback for Mark's sample file.

Replacement for the previous patch. Hopefully this fixes it for all recordings.

This bug actually manifests on all decoders that have built in deinterlace - medicodec, nvdec, vaapi2. It also manifests on avsync as well as avsync2.
The new patch fixes it on the original video as well as the two new videos from Mark.
