There is no hauppauge stuff in my x700pro vivo card, i'm not saying
that you said so, but what i'm saying is that 1 the 9800pro don't have
dxva because on the official ati web page it's not there.
"MPEG-2 decoding with motion compensation, iDCT and color space conversion
All-format DTV/HDTV decoding"
That is DXVA.
You do not need "hauppauge stuff" to have DXVA. Any DirectX 8 or later chip
should have it.
2. My video
card is capable of supporting dxva witch is relate to direct show
video encoding, so it's a directx feature.
DXVA is "DirectX Video Acceleration". Here is what Microsoft says about it:
"HDTV-capable MPEG-2 Decoder: A digital TV filter graph requires a
third-party decoder that is capable of decoding High Definition Television
(HDTV) video streams. Some decoder implementations may operate on both
audio and video streams in the same filter, while others may have separate
filters for audio and video. To achieve the performance necessary to
support HDTV, the decoder should support Microsoft DirectX Video
Acceleration (DXVA). DXVA is a specification for hardware acceleration of
digital video decoding processing, with support of alpha blending for such
purposes as DVD subpicture support."
The above is cut and pasted from

I believe that Microsoft can be expected to know their own standards.
Yes it's assist the program
to do maybe play back but it also help to decode/ripping video,
Only to decode. If you're RIPping uncompressed then it might do the trick
for you all by itself, if you're decompressing and recompressing then it's
not going to help at all with the recompression.
or to
create a back-up if you like. dxva is a hardware feature to help the
processing of reading and writing the video.
No. Just reading.
Like decoding and
encoding.
No, just decoding.
Alone it doesn't do much but it help to achieve the
processing of video processing.
I did my research and been on many web page.
Obviously not any that provide an accurate description of DXVA.
I was getting here some
confirmation on the related subject that i've start. That some
programs might use that dxva directx video acceleration to read and
write video.
It cannot be used to write video, just read. No programs use it to write,
many use it to read.
Yes there's program that do so and was like "asking" for
that name of program.
I wont ever by en TV card when i already got one. i just have to get a
TV wonder remote and voila.
Voila you'll have a system that uses DXVA to decode and the CPU to encode.
If that's what you want, fine. If you want hardware encoding though you're
going to need another board. Don't believe me, fine, believe what you want
to. If your CPU utilization is not 10% or less on analog recording though
you are not getting hardware accelerated encoding.
