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.

72c05d1cbb encodebin: Add a way to disable caps renegotiation for output stream format 
In some cases, the user might want the stream outputted by encodebin to
be in the exact same format during all the stream. We should let the
user specify when this is the case. This commit add some API in the
GstEncodingProfile to determine whether the format can be renegotiated
after the encoding started or not.

API:

9032c12e69 video-blend: fix blending of rectangles partially or fully outside of the video 
In case of overlay being completely or partially outside
the video frame, the offset calculations are not right,
which resulted in the overlay not being displayed as
expected, or crashes due to invalid memory access.

When the overlay rectangle is completely outside,
we need not render the overlay at all.

For partial display of overlay rectangles, src_yoff
was not being calculated, hence it was always clipping
the bottom half of the overlay, By calculating the
src_yoff, now the overlay is clipped properly.

Add scaler functions for 16 bits formats.
Rename the scaler functions so that 16bits versions don't look too
weird.

2f38f83c08 video-orc: comment out unused function 
A faster version of 4tap horizontal scaling causes segfaults in ORC
presumably because it uses too many registers so disable it to avoid
crashing in the ORC tests.
