    Is there a way to encode a file which is decoded by DXVA ? [e.g. a h264 file will be decoded by DXVA and will be encoded into another format. Because the processor won't be busy decoding the file, the conversion will be faster. In theory.]

    Is this possible ? Thank you.

  2. with DVXA - NO!
    with CUDA - yes!

    However you will need nvidia gfx and license for dgnvtools

    But I can play h264 files using DXVA with MPC. Isn't this a bit confusing ? I'm going to use VirtualDubMod for ripping. Isn't there an Avisyth code or something ?

  4. From what I understand (and please anyone correct me if I'm wrong), it is not possible to access the decoded video data under DXVA. The video is decoded and displayed directly by the graphics card, and not passed back into main memory for other processing.

    what you are suggesting already exists but not using dxva. what you are basically looking for is a decoder that runs entirely on the gpu, this is not what dxva is:

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

    software that allows you to use the gpu for decoding include tmpg express (mpeg-2 input only), cyberlink's espresso (both hardware encode and decode are supported with most modern video cards and mpeg-2/4 and a number of other software titles.

    if you wait a few days main concept is set to introduce it's fully accelerated avc encoding app and considering how many apps license main concept's technology we should be seeing a huge increase in software that takes advantage of gpu's.

    Thanks. Good to know. I hope those softwares make a significant decrease in encoding times.
