Thanks for the pointer! I looked around a bit in the SDL-lib and the DX3
patch for it: The output is written to a buffer, compressed with libfame to
MPEG and send it to the card.
Could be an option if you have the CPU to spare, but only works good for
static output. If you want to overlay a OSD or even a simple channelnumber
you would have to decode the MJPEG/DIVX stream to a buffer, write the osd
in the buffer, and re-encode with libfame.
Not something I'd recommend for quality, let alone performance...
To me the dxr3 avenue just turned into a dead end :-(
