Video encoding is a *very* CPU-intensive task (even a Core Duo 2 CPU is
not able to encode in realtime with every encoding algorithm). So you
have to find a balance between:

- Frame size (look how small is the video window in the SIP phone).
- Bitrate vs CPU load (if you don't need a very low bitrate, you may
send the uncompressed stream or as a series of jpeg frames)
- Quality vs bitstream, The lower is your target bitstream, the lower
will be the resulting video quality, that's obvious.

You will have to experiment with available codecs to find a optimal
combination for your case.

Best encoder for streaming video?

[Merrick Fonnesbeck]

I am writing a video conferencing application for the Nokia N800/N810
devices that stream video between two devices, and am currently using
the hantro4200enc encoder in my GStreamer pipeline to encode the video
before sending it out.  The video appears on the other side very choppy
and pixelated, and I am wondering if I am using the right encoder or
whether there is a better encoder that would compress my video better to
give me a cleaner video?  I got the code initially from the following
wiki post telling me how to stream video from the Nokia devices.

If there is a better way let me know, thanks.
