-For streaming at very low bitrates, use a low frame rate
-and a small GOP size. This is especially true for RealVideo where
-the Linux player does not seem to be very fast, so it can miss
-frames. An example is:
- at example
-ffmpeg -g 3 -r 3 -t 10 -b:v 50k -s qcif -f rv10 /tmp/b.rm

-The parameter 'q' which is displayed while encoding is the current
-quantizer. The value 1 indicates that a very good quality could
-be achieved. The value 31 indicates the worst quality. If q=31 appears
-too often, it means that the encoder cannot compress enough to meet
-your bitrate. You must either increase the bitrate, decrease the
-frame rate or decrease the frame size.
- at item
-If your computer is not fast enough, you can speed up the
-compression at the expense of the compression ratio. You can use
-'-me zero' to speed up motion estimation, and '-g 0' to disable
-motion estimation completely (you have only I-frames, which means it
-is about as good as JPEG compression).

-To have very low audio bitrates, reduce the sampling frequency
-(down to 22050 Hz for MPEG audio, 22050 or 11025 for AC-3).
- at item
-To have a constant quality (but a variable bitrate), use the option
-'-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst
