[Mesa-dev] [PATCH] st/vdpau: use bicubic filter for scaling

[Nayan Deshmukh]

I forgot to CC the list, so I am attaching our conversation here. Also
probably my R7 M265 uses
a progressive shader.

Regards,
Nayan.

I was testing with mplayer -vo vdpau:hqscaling=1 and

mpv --vo=vdpau:hqscaling=1

I also noticed another issue = my screen is 16/9 1920x1080 if I use
fullscreen
on a 720x576 vid without any aspect in it it gets stretched to 16/9
with hqscaling=0 it would be pillarboxed.

In addition if I then press "f" to change back to windowed it doesn't
resize so I see a small portion of the vid magnified in the window.

I see the list is not ccd - I think you should re add so Christian can see
this reply.

He may know what R7 M265 is better than me - eg. it may be using the
progressive shader, whereas I am using the weave shader.
