<div>Also just for a comparison between the x264 and theora
encodes, the x264 average bitrate is 190kbps with 96kbps audio
(very good quality) and video is almost as good as original DV
at full 25fps. Perhaps there's some magic theora encoding
options but it really just doesn't compete. It's also much
slower at encoding than x264 as it's single threaded...</div>

It may be negligible, but we could possibly drop the audio bitrate
down to mono 48kbps on the x264. I'm interested to know what the VP8
stuff is like now - its been a year since we last compared VP8 and
x264.<br>

<div>With more playing around with ffmpeg2theora I can get audio
at 78kpbs + video at 420kbps (total ~500kbps) and keep fairly
good video but only 12fps, and it's definitely not as good as
the x264 encode. So this is what I've updated the streaming
script to produce from now on unless someone objects. And we
should also see about other streaming servers than icecast to
support other containers beside ogg.</div>

We need to have a workshop where we throw the video into Flumotion.
We can define a workflow for Flumotion to do an on-site encode to a
500 kbps stream, and send it off-site to another Flumotion host
which transcodes this 500 kbps stream to other protocols at this bit
rate, and also at a much lower bit rate (100 kbps?), and possibly
even an audio-only stream?<br>
