<pre>Created <span class=""><a href="attachment.cgi?id=126902" name="attach_126902" title="mpv --hwdec=vdpau --vo=opengl-hq">attachment 126902</a> <a href="attachment.cgi?id=126902&action=edit" title="mpv --hwdec=vdpau --vo=opengl-hq">[details]</a></span>
mpv --hwdec=vdpau --vo=opengl-hq
I noticed, that when I play videos with mpv using VDPAU I'm getting an image
that looks like deinterlacing/anti-aliasing is not working, making fine
structures/patterns or text look ugly/unreadable. Playing the same video with
the same stack but using VA-API doesn't exhibit this issue.
Attached you'll find a screenshot taken with VDPAU when playing a video using
mpv --hwdec=vdpau --vo=opengl-hq
The only difference for the VA-API playback is using "--hwdec=vaapi". I would
say that this is a regression, but I can't remember when it started. :-(
The stack showing this issue is (Debian testing as a base):
GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1)
Mesa: Git:master/e4b585f009
libdrm: 2.4.70-1
LLVM: SVN:trunk/r282761 (4.0 devel)
X.Org: 2:1.18.4-1
Linux: 4.7.5
Firmware: firmware-amd-graphics/20160824-1
libclc: Git:master/88b82a6f70
DDX (amdgpu): 1.1.2-1
Let me know, if you need anything else.</pre>
