![]() The next thing I noticed is that for my combination of hardware and software at least mpv tends to take about 2/3 the CPU time to play videos that mplayer does on every video I tested. Basically I need a new high-end video card to get VP9 decoding and that’s not something I’m interested in buying now (I only recently bought this video card to do 4K at 60Hz). The Wikipedia page about Unified Video Decoder shows that only VCN (Video Core Next) supports VP9 decoding while my R7-260x video card has version 4.2 of the Unified Video Decoder which doesn’t support VP9, H.265, or JPEG. So in most cases hardware decoding isn’t going to help me. The first thing I noticed is that mpv was unable to use VAAPI on my laptop and that VDPAU won’t decode VP9 videos on my workstation and most 4K videos from YouTube seem to be VP9. ![]() I did a number of tests on playing different videos on my laptop running Debian/Buster with Intel video and my workstation running Debian/Unstable with ATI video. The other comment suggested that I try the mpv fork of Mplayer which does support VAAPI but that feature is disabled by default in Debian. ![]() It seems that mplayer doesn’t suppoer VAAPI. I also found the Debian Wiki page on Hardware Video Acceleration which has some good information (unfortunately I had already found all that out through more difficult methods first, I should read the Debian Wiki more often. One pointed out that I should be using VA-API (also known as VAAPI) on my Intel based Thinkpad and gave a reference to an Arch Linux Wiki page, as usual Arch Linux Wiki is awesome and I learnt a lot of great stuff there. After writing my post about VDPAU in Debian I received two great comments from anonymous people.
