vbr questions
Hello,
I am working on a real-time app for embedded hardware. I have two
questions about the variable bit-rate option:
1. Can one designate a maximum bit-rate with the VBR option?
2. Does VBR chunk the bit-rate up and down, i.e. what is the
granularity/speed of the changes in the bit-rate and can that granularity be
defined and/or defined on the fly?
Thanks so much for your help.
