Description Łukasz Żarnowiecki 2016-07-08 14:12:42 UTC
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.

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.

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.

No.  I will try and test with mesa 12.0 soon.
Comment 4 Łukasz Żarnowiecki 2016-07-16 12:41:46 UTC
I tested mesa 12.0.1 and the problem is fixed.  Affected version is 11.2.2.  Should I close this one?
Comment 5 Christian König 2016-07-18 13:11:53 UTC
I'm still curios what could have been the issue here.

But that doesn't sound like something we need to push on.
