I have a Radeon RX550 card which I use for HDMI output. The OS is Xubuntu 20.04 runni18ng Kodi 18. The problem is however not limited to Kodi, other media players show the same problem, like Mplayer.

I am experiencing the same with a camera stream mp3 that I record and then play via VLC.
Haven’t found a solution but my guess is that this is about a difference in how many frames/sec had been recorded and how many are played.
So may an input source have provided a lower frame rate at some point?
