Hi,

 

 

When WatchOut playing the movie(h264 or mpeg2) ,Is DXVA working on GPU?? 

 

Please see below for the details of DXVA:

 

https://en.wikipedia.org/wiki/DirectX_Video_Acceleration

 

 

 

My PC spec:

Windows7 64bit

WatchOut version: 6.1.6

Using Graphiccard: AMD fireproW7000

 

thank you

 

After the initial logo screen is replaced by content,

anytime a full screen image is displayed by WATCHOUT Display (even if it is nothing but black)

it is operating in hardware accelerated Microsoft DirectX 3D rendering mode.

If you switch to WATCHOUT Display "window mode" (Control-W) rendering drops back to Windows GDI,

switching back to full screen re-engages Microsoft DirectX 3D rendering.

 

However, WATCHOUT does not normally utilize optional video decoding hardware on a graphics card,

movies are decoded completely in the CPU and then streamed to the GPU.

   related: Tip: WMP and QT — disabling hardware accelerated decoding

 

(Exceptions in 6.1.6+: HAP variants on all Display servers,

h.264 or mpeg2 only on WATCHPAX variants.

These exceptions do use the GPU to decode movies)

I understood that Watchout  decoding movies on CPU.

Is it difficult  all Display servers use the GPU to decode movies(h264 or mpeg2)??

 

HAP is good codec,

however it consume a lot of HDD resources.

Yes, when using the generic Windows DirectX calls,

it is difficult to get consistent reliable results from the various vendors cards.
