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