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

1. Otherwise rotating the video will clip and show black bars due to
gltransformation's implementation.
2. The other option of make gltransformation aspect-agnostic produces
incorrect output with perspective transformations.
Actually set the configured framerate. Before we only used to set the first
matching framerate range. On iOS where the camera reports ranges [2, 60], we
used to configure the camera to output anything between 2 and 60fps.
Add a "mask" property that sets whether the edges by cvLaplace should be
used as a mask on the original input or not. The same way the original
image is copied to the edges in edgedetect.
Add a "mask" property that sets whether the detected derivative edges
should be used as a mask on the original input or not. The same way
the original image is added to the edges in edgedetect.
