Because I read DXVA 2 docs a while ago and they didn't mention this possibility. Also the DXVA (1 or 2) APIs take an encoded picture and returns nothing If it was possible to grab a decoded picture back from the GPU memory (which I doubt), then ffdshow internal filters could work EDIT : the patch you mentioned is from VLC team, not ffmpeg. The benefit I see is that APIs are finally all included into ffmpeg but there are still some stuff that have to remain into directshow layer (so ffdhow code) such as the DXVA allocator... But afterwards it is not very different from MPC patch, maybe cleaner, I don't know yet Last edited by albain; 29th December 2009 at 21:34. |

the company that owns DTS is very willing and able to sue anyone who dares to try. But the main reason is that they keep all their technoligy secret, reverse engineering from nothing is very difficult.

I agree Support for <Vista is more important than WinXP. It's an outdated OS with some issues in media support compared to later Windows versions. Maybe detecting Windows version and applying DXVA1/2 accordingly would be feasable?

That's not my feeling on it, no. Back when I was doing DVD regularly, DTS always sounded much better for a variety of reasons. One of which is the higher bitrate, but, there are others, too.

I don't want to take this thread further off topic, but, that should help.

DTS is should be better, but i doubt it really matters for realtime encoding

There is a soc project for dca encoding here:
svn://svn.mplayerhq.hu/soc/dcaenc This source is based on code from here: http://roundup.ffmpeg.org/roundup/ff...0080207.tar.gz |
