Dear schrodinger developers,

What are good parameters for the gstreamer schroenc element?

I have been experimenting with the schroenc element and standard test
video samples at CIF resolutions.  I have been experimenting with various
encoder options, in search of a setting that produces acceptable quality
video that can be played back at full speed on my OLPC XO.  At the moment,
my pipeline is:

gst-launch filesrc location="flowers.avi" ! decodebin ! schroenc
bitrate="500000" rate-control=1 ! oggmux ! filesink location="flowers2.ogg"

When I play it back with

gst-launch filesrc location="flowers2.ogg" ! decodebin ! xvimagesink

the video is terrible quality, and it does not play back in real time.  I
am using schrodinger-1.0.0, compiled with -O3 -march=geode
- -fomit-frame-pointer.

What range of parameters is most likely to yield acceptable quality for
CIF video, and produce video that can play back in real time?

- --Ben
