Hi,
Here is the number for encoding and decoding Theora on XO-B2.
For comparison, the same test is run on Athlon-XP1800+.

The test uses dump_video and encoder_example in Theora
examples. The output is directed to /dev/null. The video
quality is set to 3 for encoding. The decoding runs for
first 120 frames only. XO's wireless is off while testing.
The encoding samples are from

The decoding samples are collected from the net:

Hi Chih-Chung,
were these results with or without mmx optimisations ?
The decoding results look fairly reasonable up to a frame size of about
640x480.
There are some further test ogg files you can use at
