Question / Help OBS and DXVA2

[willis_007]

Good afternoon everyone,

Is it possible to configure the OBS video output for decoding to 'DXVA 2.0' instead of the default 'Direct3D 11' ?
I'm not talking about the 'Encoder' part of the 'Exit' menu but the 'Render' option of the 'Advanced' menu.

Thank you in advance for your help :).

No one can really help me please :/ ?

Not possible.

'Media Source' of obs has option to use HW acceleration (if any).

Hi Suslik V,

Thank you for your answer.
And so, HW acceleration will use by default Graphic Card processor you think ?
Besause, I tested it, no change on CPU charge :/

OBS Studio require acceleration (or it simply refuses to start). Capturing is demanding task. That's all.
If you able to start the OBS Studio, then it already utilizes all needed HW acceleration.

Okay.
Thank you for the answer.
So if my CPU load climbs to 80% average but also that of my graphics card (as shown in the printscreen) is that neither is powerful enough to ensure these decodings without saturating.

Not having the ability to tell OBS to use only the graphics card to decode RTSP streams, so I'm going to upgrade my I5 to an I7 7700K 4GHZ.

I think that should improve the load you do not think?

Solved :).
I bought an I7 6400K which is multi-thread for each core. This aspect is very important to decode multi RTSP streams with no soucy. Now the charge of my CPU is 30% ^^.
