I don't see what your'e trying to do overall here...you're using the
"hardware acceleration" to get mjpeg images, but then you're
converting them?  Does this give you a higher fps rate or something?

Your hypothesis is that the warning message "No accelerated colorspace
conversion found" is what's causing your extra latency?  Is it using
100% cpu?
You may want to try removing all traces of ffmpeg (libav*) from your
system and rebuilding...
