[Ffmpeg-devel] Ratecontrol problem
Thu Oct 12 15:23:44 CEST 2006
I use the latest svn.
Even if I change bitrate tolerance to a higher value it does not work...
The only way I found to reach the desired bitrate is to change the frame
size to a lower resolution but I need to keep the original size.

-bt 1 is significantly too small

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
