Optimize theora decoding with msa in functions:
1. ff_vp3_idct_add_msa
2. ff_vp3_idct_put_msa
3. ff_vp3_idct_dc_add_msa
4. ff_vp3_v_loop_filter_msa
5. ff_vp3_h_loop_filter_msa
6. ff_put_no_rnd_pixels_l2_msa
Theora decoding speed improved about 36%(from 22fps to 30fps, Tested on
loongson 2K1000).
This patch is just a quick example to show how to fill the ROI info,
it does not ask for upstreaming, just for your reference.
to verify the ROI feature with this example, the command line looks like:
./ffmpeg -i .../path_to_1920x1080_video_file -vf scale=1920:1080 -c:v libx264
-b:v 2000k -y tmp.
This patch just enables the path from ffmpeg to libx264,
the more encoders can be added later.

The encoders such as libx264 support different QPs offset for different MBs,
it makes possible for ROI-based encoding. It makes sense to add support
within ffmpeg to generate/accept ROI infos and pass into encoders.
Typical usage: After AVFrame is decoded, a ffmpeg filter or user's code
generates

after 153b36f there is a possibility to crash when trying to get index of
a surface which points to nirvana. it may occurs when a mpeg2 stream starts
with non i-frame.

You are not allowed to do that. FFmpeg is not your personal project, it
is a collective endeavour governed by cons

Hello,
so now I've taken the time to integrate the alternative interpolation
algorithm 'uglarm' into the delogo filter.
I took the code from ffdshow's logoaway, which took over the code from
LogoAway for VirtualDub, where I originally added it 2001. :)
I tested the code with several differe
