DXVA2 experimental hw decoding

[mean]

and with libva ?
(you need the libva / vdpau wrapper installed)

[eumagga0x2a]

Done: the same CPU load (~28% ââ,¬â€œ ~30%) for 720p h264 25fps videos. Both decoder and display driver are set to LIBVA, which requires disabling VDPAU in the preference settings to prevent it from taking over.

Coud it be the window manager messing up with  the performances again ?

[Jan Gruuthuse]

Hard to tell: libva seems to spread the load more evenly over the threads.

Under attack?

Unlikely, because turning hwaccel off adds only ~10% to the CPU load (it grows to ~40%) and dedicated media players like MPlayer and mpv consume only ~5% of CPU when playing 720p h264 videos (in a window, not fullscreen) via VDPAU in the same gnome-shell setup.

Redraw problem should be fixed
Just the mm patch to look at and it is ready for testing

After the current PR, I'll do at least 1 more patch wrt Dxva init...

Fttb, (init succeeds then) decoding doesn't seem to succeed on my computer:

  Avidemux v2.6.14 (161115_eb280212ed3) .

Operating System: Microsoft Windows Vista Home Premium Service Pack 2 (6.0.6002; 32-bit)

It's maybe normal
There is a delay of a few frames at the beginning

Agreed: on second look, decoder seems to (then) succeed.

Surface to admImage = 095232C0
Retrieving image pitch=768 width=720 height=576
Align 576,16 => 576

Yet, while Audio was fine, Video seemed as if (very) slowed down, and cpu may have been (much) higher than without Dxva.
But I'll try it again, with a newer build...

Decoder and Renderer can be used independently, can't they?
(Maybe we could had a few (raw) statistics: decoded frames, displayed frames, ...?)

[mean]

with the current D3D9 they are always independant, with an extra copy as consequence

And what NVRESIZE? Supported?

[mean]

on linux , with vdpau
