274984e83b video-frame: Relax width/height assertion 
When doing CROP META it is exepcted that the width and/or height in the
GstVideoMeta is bigger or equal to the caps negotiated size.

3cd2eb5847 video-converter: fix border handling of YUY2 and friends 
Don't draw the border in groups of 4 pixels for YUY2 but instead in
groups of 2 with alternating U and V. This avoids a crash on odd width
borders.

0d333d8d44 video-converter: add table based matrix8 implementation 
Based on patch from Mozzhuhin Andrey <nopscmn at gmail.com>

Add a table based matrix8 multiplication implementation. The algorithm
does not do any clipping so we need to make sure we never call this on
input that might need to be clipped. In general, this algorithm is
2 times faster than the orc optimized one and would be chosen for all
RGB -> YUV conversions and some YUV->YUV and RGB->RGB conversions.

557c2c9be1 audiobasesink: Reset audio clock if necessary 
When the ringbuffer is deactivated and then acquired, if the audio clock
provided by the sink gets reset to zero, we need to add an offset to the
clock to make sure that subsequent samples are written out at the right
times. While we need to leave this to derived classes to take care of
when they provide their own clock (since that clock may or may not be
reset to zero), we can do this ourselves if we know the provided clock
is our own (which does reset to zero on a re-acquire).
