out of order? that was never supported, it of course might work fine
as long as the NAL units are just reordered within one frame
but as soon as NAL units are reordered between frames you are left with
either buffering all NAL units until you have a complete frame (might
never happen if the NAL unit is really lost) or decode and output
the frame with a missing slice, the current decoder will always do
the later ...

what is supported by the H.264 decoder now which wasnt in the past
is decoding indicidual NAL units instead of just whole frames
