[Ffmpeg-devel] Intra-frame rate control

I'm trying to use avcodec.lb to encode 1920x1080 frames in MPEG-2.  I've
noticed that the Q value for all the slices in each encoded frame is always
constant.  Is this a limitation of avcodec.lib?  In other words can the rate
control only adjust Q values at picture boundaries and not at slice
boundaries?  Is there a setting somewhere to allow the library to adjust the
Q within a frame instead of only at frame boundaries.


Thanks in advance,
