Actually we've got it all figured out. We have x264 recipies that work great
we are trying to bring them over to ffmpeg because it's faster and a single
pass no muxing packing and other wasted items. The problem is
I can't get -bf to be honored at this point.
It takes the parameter and silently does not thing
with it. So that's the last remaining piece....
Has anyone gotten -bf or -bframes to work for h264 and ffmpeg?
All of this will likely wind up in the iSquint project if I can persued
Tyler to use these settings... He's already set on ffmpeg.
