Hi all,
Recently, the uvd supporting is released, and we've tried it on loongson 3a platform. Brief introduction about loongson 3a, it's a MIPS III compatible, 4 cores processor.
More details about the platform [1]: * The Board: RS780E + SB710 chipset, with an AMD radeon HD6570 video card * The kernel is 64bits(n64 ABI), and the userland is 32bits(o32 ABI) * OS: LOonux 3.3.6 [2] + LTP-uvd-installer-20130419.bin [3] ** kernel: 3.9 + uvd related patches ** mesa: git master version (d0e9aa)
We tried three video samples: * big_buck_bunny_1080p_h264.mov (http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_108...) * Sintel.2010.2K.x264-VODO.mp4 (http://dev.lemote.com/files/upload/software/UVD-debug/Sintel.2010.2K.x264-VO...) * test.avi (http://dev.lemote.com/files/upload/software/UVD-debug/test.avi)
For big_buck_bunny_1080p_h264.mov, the playback is not very fluent at the beginning, and it has some video mosaic. We've recorded a video for it, see http://dev.lemote.com/files/upload/software/UVD-debug/bbb-1080P.mp4 For video mosaic, what could it be caused by?
For Sintel.2010.2K.x264-VODO.mp4, it has a very long wait for the first frame. We've also recorded a video for it, see http://dev.lemote.com/files/upload/software/UVD-debug/sintel.2K.mp4 Any idea about the long wait for the first frame?
For test.avi(video: ITU H.264, 1920x1080), it's playing back perfectly! Thanks for the effort on UVD!
In all of these tests, the CPU usage is around 50%, and all three video samples play well on X86 platform with the same video card.
BTW, 785G also has UVD2.0, is it supported currently? Or will it be supported in the near future?

Due to platform limitation, Loongson-3a use 16KB page, and X86 use 4KB page, maybe this has some relationship with the video mosaic?

Early UVD 2 chips like RS780/880 and RV770 are not yet supported due to differences in the UVD hardware compared to later generations. We are currently looking into supporting UVD on those chips in open source, but nothing is available yet.

That looks like a known problem with the semaphores and also happens on X86, it gets worse when you have a slower CPU and/or less bandwidth cause then UVD needs to block on the DMA to wait till everything is in place. I'm going to try to release the workaround for it.

No idea, that also happens on X86, but the wait is actually not as long. If I'm not completely wrong it seems to be mplayer who is causing this startup delay.

No, as Alex already stated that chip is quite different to the other UVD generations, and we are currently looking into releasing code for it, but can't promise anything.
Cheers, Christian.

With '...when you have a slower CPU and/or less bandwidth...' you naturally mean my Duron 1800/RV730 AGP (!!!) system, am I right? ;-)
Yes, that's the problem I get since the 'shadow' is fixed. I can get it much faster when I go forward or backward in mplayer.
Do you have anything released?

I mostly don't see such delay, here. But hey, I get this with test.avi, now:

Perfectly, with such mosaic, after some few seconds? And your test.avi is not seekable.

Are you guys interested in OpenCL (on your platform)? OpenCV (one of the basis for digikam for example) has some support for Nvidia and now AMD. It is under development by Institute Of Software Chinese Academy Of Science. AFDS 2012 http://www.youtube.com/watch?v=LhIuSShTO0g
Even the next big Gimp version (2.10) should be accelerated by OpenCL through GEGL.
Wouldn't it be cool to have OSS OpenCL even for 'smaller' sized gfx cards from AMD? You are a hardware shop so maybe your demand is it AMD worth to have something around?
