When using hardware decoding with radeonsi along with mpv I can observe aliasing on rough edges. It was previously reported on mpv issue tracker https://github.com/mpv-player/mpv/issues/3317 but the main developer pointed out that the bug is in mesa.
Does this happen with -vo vdpau as well? If not it sounds like the deinterlacing shader in mpv doesn't work 100% correctly.
> Does this happen with -vo vdpau as well? No. It didn't happen with mapping video mixer output surfaces in GL either. This issue came up because mpv started to map video surface textures directly. > If not it sounds like the deinterlacing shader in mpv doesn't work 100% correctly. Any clue what could be wrong? (See linked mpv bug report.) Also, another user replied and claimed it got fixed by updating to Mesa 12.
> Does this happen with -vo vdpau as well? No. I will try and test with mesa 12.0 soon.
I tested mesa 12.0.1 and the problem is fixed. Affected version is 11.2.2. Should I close this one?
I'm still curios what could have been the issue here. But that doesn't sound like something we need to push on.
