cf572ae2cb video-info: use default colorimetry on error 
When we fail to parse the colorimetry property, fall back to the default
colorimetry for the format and dimension instead of leaving things
undefined.

8296cdbfd5 video-converter: only convert to/from rgb when needed 
Only use the YUV->RGB matrix when we have YUV as input and only use the
matrix when we need to make YUV output.

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).

cd07101420 tagdemux: ensure tags have been fetched before pulling data 
Otherwise upstream can get confused about offsets as there will
be a jump once the tags have been parsed due to the stripped area.

If upstream pulls from 0 to 100, and then tagdemux does the
tag reading and finds out that the first 200 bytes are the tag, the
next pull from upstream will have an offset of 200 bytes. So
upstream will get the following data:

0 - 100, 300 - (EOS), as it will continue requesting from where
it has last stopped, but tagdemux will add an offset to skip the
tags.

This patch makes sure that the tags have been parsed and skipped
since the first pull range call.
