Hello, I’m running Manjaro Sway on Pinebook 11" 1080p. I’ve decided on this distro because it had flawless, smooth and hw accelerated video playback through mpv when I installed it about a year ago. I’ve downloaded som test videos in various formats (mpeg2, mpeg4, h264, vp8, vc1) and sizes (1080p, 720p, 480p) and the Pinebook successfully played smoothly all of them (except 1080p version of vc1 or vp8 I don’t recall which one). I’ve periodically checked the video playback after every update and when there was no issue after half a year, I stopped to check.
After last update I remembered my video testing and just for fun I’ve tried to test the video playback again. And I was surprised to find out, that none of the 1080p videos were smooth. All of them had frames drop.
Does anybody know why, the video playback stopped to be smooth?
I’ve read somewhere, that from some graphics drivers video hw acceleration was dropped recently, could it be this case? If yes, how can I fix it?
Here is output of mpv when playing the mpeg2 video:
