    DXVA (native)唔support madvr，同其他decoder嘅硬解可以話一樣

CUVID同DXVA (copy-back) 都support madvr

理論上分別不大，不過好似CUVID穩D..................

Is Nvidia CUVID better or DXVA (native)?
I was using DXVA (copy-back), and I found no problem!

CUVID is better, if your card is by nvidia.
CUVID is a CUDA decoder just for nvidia card.

唉~ 我都想玩 CUVID....
仲用緊 ATI HD48xx 乜野新加速計算功能都無份用, 唯有全部只靠 CPU 硬上 =_=
唉~ ATI 講就無敵, 真正用起上黎, 要乜野功能佢就無乜野功能, 我呢世都唔會再買佢任何產品!

test done. 多謝指正.
確定 LAV & ffdshow 只有 RGB 先會係預設 full range output, YUV 一定係 limited range 無得改, 咁即係 madVR 乜都唔洗搞, post deleted.
可能呢排睇得太多資料, 搞到亂晒 T_T;

EVR 既 YV12 chroma 有好大問題, 由其係一大片紅色既位, 直頭係嚇死人....
一定要用 EVR 的話, 你最好開 shader YV12 chroma upsampling 去保救....

I mentioned that in one of my previous post, u have to disable automatic exclusive mode in madVR.

Yes, free Calibrize, does this one produces the ICC profile u talked about?

But without able to easily adjust brightness, that's just hard.  Cause once the color is calibrated, it's fixed.  But some films are darker than others, not sure if intended or other factors.  And those need to be brighter.

I'm using GTX 270, and I was using CoreAVC3.01, if that set to CUDA, auto deblocking is on even to disable, and video stutters in some scenes!  I still think native DXVA hard decode has some advantage over CUDA instructions, but that probably due to the inefficiency with CoreAVC!

How do you find out how many times the color range conversion has been done?  And how to find out the limited/full range is used?  Or simply, how do u open that info bar on left of MPC-HC?

My conclusion so far:
maintain film feel: KMP + internal Gabest mkv splitter + VMR9 + LAV
for 60fps: MPC-PC + SVP + LAV + madVR  * but video may be jerky depends on the source!
