apparently not sufficient to show up in fate

  mjpegdec: Properly set the context colorspace info

See: c11043acMerged-by: Michael Niedermayer <michaelni@gmx.at>

Since audio clock calculations are more accurate now, it is safe to decrease
the sync treshold to compensate the larger buffers caused by less frequent
audio callbacks.
Signed-off-by: Marton Balint <cus@passwd.hu>

Too many audio callbacks per second can cause buffer underruns especially under
load. As now we take into accound the elapsed time after an audio callback when
determining current audio clock, it is not that important to use small buffer
sizes and frequent audio callbacks, so lets remove the comment.

No change in functionality.
Signed-off-by: Marton Balint <cus@passwd.hu>

Instead of directly rolling back the frame queue, keep the last displayed
picture in the queue and use a boolean variable to keep track if it is
displayed or not. This makes the code cleaner because it removes the
complicated logic in pictq_prev_picture.

There should be no change in functionality.

This surely can be optimized more, i just didnt want to cause a slowdown
