Will H.264 VA-API / VDPAU Finally Come To Gallium3D?

[bridgman]

Seems like a duplication of effort to me. Wouldn't it be better if AMD just contributed to the r600g driver hosted at freedesktop.org, instead of writing their own Gallium3D driver?

I think he means r600g. AMD's not writing 'their own' Gallium3D driver. Sigh.

I think Michael meant "the Gallium3D driver for their hardware", which a lot of people shorten to "their Gallium3D driver" even if that is not strictly equivalent.

Give it a few weeks, and I'll be sending my initial VP8 OpenCL implementation to the WebM mailing list to live in a sandbox while I continue work on it post-graduation. It's functional, but much slower than CPU-only decoding at the moment. It does at least produce correct output... in its own good time.

Once its in the sandbox and my thesis is finished up, I wouldn't object to anyone helping me out with getting the performance up to speed.

Good news, thank you!

Let's hope that we'll have an opencl state tracker to actually use it.

Now, THAT sounds fantastic! Great work!

Now we need Clover

You know what would be really helpful.
If they started with doing this with MPEG-1 and 2.
Work their way up to the present.

AFAIK, MPEG2 works. Christian K?nig has a working XvMC implementation, for r600g. I haven't tested it, but others have, and it's working (not perfectly optimised yet). He also has iDCT working and some other stuff.

And why is everybody trying to make H.264 get a foothold on Linux?
Please support FLOSS formats/libraries instead of the latest flashy thing like H.264.

Most of the steps which any modern high-quality codec does are similar: iDCT, motion compensation, etc. If it's done for H.264, it can be easily ported to other codecs. The main difficulty is getting the infrastructure and a reference implementation down.

If you spend a little more time on making sure your articles are correct without ambiguity and a little less time on fluffing up your articles with irrelevant stuff just so you can squeeze in more links to yourself, maybe people would start taking phoronix seriously. Just maybe.

wasn't there another GSoC project few years back that was trying to do the same thing and in the end we got nothing????

The two main projects that I can think of were:
1) Younes Manton, GSoC project. g3dvl, already mentioned in this thread
2) Robert Rudd @ MIT. Another GSoC project that attempted H.264 decode via GLSL shaders using the ffmpeg/libav framework as a starting base. He got some stuff working, but didn't finish the project. Someone forked his code and at least got it to compile: https://github.com/kasbah/gsoc.

AMD has also experimented with XvMC for their Gallium3D driver

In the previous thread on this topic it was mentioned that the developers who had originally started a VDPAU implementation were considering moving their work to VA-API.

We have worked on a vdpau state_tracker, but are considering moving to vaapi instead due to complications with implementing a brand new bitstream decoder.

[mattst88]

also how sure you are that i am not involved one way or another in projects?? (not that it matters if i do or not)

I'm not sure, but I certainly have noticed an inverse correlation between the number of complaints made and the amount contributed.

I have no issue dressing in drag for good video accel.

That was a reminder of UVD being available for windumbs since start, and its equivalent for linux only being in plans written by 3rd party(student@now) now. Video accel itself is always good.
