[FFmpeg-devel] Add on-the-fly bitrate adjustment for encoding

[Adrian Cable]

This is an addition to ffmpeg.c which enables on-the-fly encoder (e.g. H.264) 
bitrate adjustment using ffmpeg interactive mode. For example, specify “-b:v 
299k -bufsize 299k” on the command line to start encoding at 299kbit/sec, then 
to adjust the encoder bitrate to 200kbit/sec during encoding, type:

 

r20

I really think this is a bad idea. You should be using the API for this.
Soon we will have every feature reconfigurable from the CLI, it will be
unmaintainable.
