It gets rid of a switch (with accompanying CONFIG_*_ENCODER checks); for MJPEG, it even lets one perform the check for whether one is really encoding or only recording the macroblock once during init. Furthermore, the switch actually contained lots of dead code -- it is compiled three times (for different pixel formats: 420, 422, 444), yet most encoders only support 420. The approach used here automatically fixes this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
