49d909dabf video-scaler: add more ORC functions 
Add the old ORC functions for nearest and linear. Label them as Low
quality because they are not as accurate but ORC lacks opcodes to
express this for now.

ca2bd1cc6b video-scaler: rename resampler to video-resampler 
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.

daf20d5e09 video-scaler: remove color range argument 
We just need to clip to the format limits, if there is extra headroom in
the range we can use that without problems.

199fab4b06 video-scaler: add video scaler helper object 
Add a video scaler object build on top of the resampler. It has
implementation to deal with interlaced video as well as horizontal and
vertical scaling functions.

549bdd4ece video-converter: rework the generic converter function 
Use a LineCache object to track and process lines between unpack,
upsample, convert, downsample and pack stages. This simplifies the
main core processing function a lot and allows for future additions
easily.

Add support for interlaced formats in chroma up and downsampling.

8b8b8ae2e8 Revert "decodebin: fix the autoplugging of parser elements" 
This reverts commit 2b0d392741.

This breaks cases where an actual second parser is required after the parser,
e.g. to do timestamp corrections.

aa94d5dc9a decodebin: Fix locking

around a bit to require only one lock() and unlock().

2b0d392741 decodebin: fix the autoplugging of parser elements 
If there are two parser elements available for the same media format,
then decodebin is autoplugging an extra capsfilter and parser irrespective
of caps and rank. So restrict the decodebin from autoplugging multiple parser
elements back to back in adjacent positions with in a single DecodeChain
for the same media format.

2f60c9c4fe tests: parallelise 'make valgrind' 
Use $(MAKE) instead of 'make' inside the Makefile,
otherwise the make will run as if -j1 had been
specified and complain about the job server not
being available, and with $(MAKE) in inherits the
parent make's settings it seems.

Upgrade common submodule for parallel check-valgrind.

3f5b9c4c8b videoblend: Avoid assigning a negative value to a guint 
There are some few but certain conditions where it is possible for the
dest_width to be smaller than x. So we check this before assigning a negative
value to src_width, which is a unsigned and would be promoted to a number that
can segfault videoblend.

1cc311156c basetextoverlay: Fix segfault when overlay outside the frame 
When the textoverlay is set outside the video frame by deltax or deltay the
calculation segfaults, but it is also  unnecessary since it doesn't need to be
displayed. So we should clip the text.
