Useful when gst_gl_window.c::gst_gl_window_new is not used.
This is the case when using a custom GstGLWindow.
(ex: GstGLWindowGPUProcess from Chromium)
Was never ported and doesn't look like
we want it or need it in this form, can
do the same with the libgstvideo sample
conversion utility API now, but better
and in a more flexible way.
Just check whether LATM is defined which is only available
in 2.7 and later. Allows us to simplify the configure check
a little and we can get rid of some hackish workarounds for
problems with earlier version headers.
The frame available callback can be called after deconfiguring the amc codec.
Guard against this by setting the back pointer to NULL on close() and ignoring
any NULL data pointer.

Rework the GL context code. Now both avfvideosrc and vtdec can create an
internal GL context for pushing textures. Both elements will still try to
use/switch to a local context where available (including after RECONFIGURE
events).
On some embedded systems, sqrt() is not supported in the shader,
use the actual value of sqrt(2) instead.

When the framesize is not specified, we try and calculate a size from
the strides and offset information. This was done with the sum of
offsets + the size of the last frame. That is just wrong method. We also
need to account for video meta that may be flipping two planes. An
example is if you convert I420 to YV12 by flipping the two last offsets.

Don't put relative paths in pkg-config files, including uninstalled
ones. For those, use @abs_topbuilddir@ and @abs_topsrcdir@ as we
do elsewhere.
Remove libraries= directives, which doesn't seem to be a pkg-config
variable that actually exists, but has been in all our pkg-config
files for as long as they've existed.
To make parser work with image having non-standard strides, plane
offsets or with padding between images.
For now, since element doesn't check for videometa, we can't directly
push buffers when these properties are set so it convert the frame
in the pre_push_buffer method to remove any custom padding.

Allows the subclass to completely override the chosen src caps.
This is needed as videoaggregator generally has no idea exactly
what operation is being performed.
- Adds a fixate_caps vfunc for fixation
- Merges gst_video_aggregator_update_converters() into
gst_videoaggregator_update_src_caps() as we need some of its info
for proper caps handling.
- Pass the downstream caps to the update_caps vfunc
