Have you tried Google?

druscelli 14-May-12 4:28am

yes very much!!! but on google I found a lot of material and don't know what's suitable for me.
CUDA?
OpenCL?
DXVA?

And I didn't find a valid simple tutorial. Just general informations.

Well we don't know what's best for you either, you need to study the different materials and decide which one fits your needs.

druscelli 14-May-12 4:52am

do you have some simple tutorials?

Richard MacCutchan 14-May-12 6:03am

No, Google has.

druscelli 14-May-12 6:12am

sorry Richard, as I said I googled a lot but couldn't find. If you don't believe me, look at this http://www.smalllinks.com/10QN
Maybe I don't use right keywords but I don't have idea what are right keywords to find a good tutorial on how implement c++ video encoding / decoding using gpu and hardware acceleration. I hope someone better then me can help me.
Bye

Maybe you are right; this is the best I could find.

druscelli 14-May-12 7:00am

no, it's not what I'm looking for. Anyway thanks for your time.

Maybe one of these may be some use.

Solution 1

Sign up at ATI and NVidia as a developer for OpenCL, CUDA, etc... and you'll gain access to sample code from their SDKs. These include encoder/decoder examples.

When in doubt, go to the folks that manufacture the technology and sit on the standards boards.

On a side note, I see that NVidia has recently decided to OpenSource CUDA!

Nice!

what about DXVA? I didn't find a decent tutorial, just general info.
