7175417f7e video-converter: remove check for below zero for unsigned int
CLAMP checks both if value is '< 0' and '> max'. Value will never be a negative
number since it in an unsigned integer. Removing that check and only checking
if it is bigger than max and setting it appropriately.

e1715f7728 video-converter: only make a scaler when we are scaling
Only make a scaler when we are actually doing any scaling. Without
scalers, the scale function will simply do a copy.

cdd86d025a video-scaler: add 2d scaler
Make a convenience function that combines 2 scalers to perform a 2d
scale. This removes quite a bit of overhead in method calls when doing a
typical scale and it also can reuse a piece of unused memory in the
vertical scaler.
Use the 2d scaler in video-converter and remove the other scalers and
temp memory.

4956800549 videodecoder: accept-caps should only require fields from the template

that are not required by the decoder (framerate for image decoders) and it

The accept-caps implementation will do 2 checks:

1) Do subset check with the template caps, making sure all the required
fields that are present on the template are present on the received caps.
2) Do a intersection check with the result of a caps query, making sure
that downstream can accept the fields in the received caps.

f24075887f videodecoder: implement caps query
Refactor the encoder's caps query proxying function to a common place
and use it in the videodecoder to proxy downstream restrictions.

The new function is private to the gstvideo lib.

8baf1ec500 videopool: update buffer size after video alignment
Update the new buffer size after alignment in the pool configuration
before calling the parent set_config. This ensures that the parent knows
about the buffer size that we will allocate and makes the size check
work in the release_buffer method.

3fc5791b3f Revert "video-converter: Fix compiler warning because of missing prototype of non-static function"
This reverts commit 406f32a946.

The problem was apparently that my video-orc.h was not updated and did not
include the prototype for that function. Only a "make clean" caused it to
be regenerated.

2034e5c153 videodecoder: do not use fixed caps on source pad
decoders can change the caps on their source pads, so they don't
use fixed caps. Having fixed caps can cause renegotiation issues.
