Start by reproducing the issue with mpv rtp://@233.33.210.16:5050 and compare its output with ffplay using the linked stream log and tcpdump capture. Use the supplied mpv and FFmpeg versions and Gentoo Linux environment to investigate the periodic audio/video artifacts; done means RTP playback is artifact-free or the cause is identified.
