I am using the latest Infuse 7.3.1. I have a .mkv file with H.265 codec and when I play this file with PiP on my iPhone (iOS 15) there is a problem.
The playback bar moves very fast constantly from beginning to end and this over and over again. It is not in sync with the playback time.
This problem appears only with .mkv files that have H.265 or H.264 codec.
