bea4d13a99 meson: gl/gtk tests: Add video_dep to the helper
The gtk helper library includes videooverlay.h hence must have a
dependency on video_dep, this allow removing the dep from the dependant

4fa850e3e6 audiorate: accumulate offset by time diff
The fomula, 'offset = time / rate', is correct only if
the rate is never changed. When the rate is changed,
the offset should be re-calculated based on the previous
offset.

22373acee3 tests: simple-launch-lines: fixate audioconvert caps now that the layout is also convertable
Because audioconvert can now convert between interleaved and non-interleaved,
this pipeline fails on the upstream capsfilter not being able to fixate its
output caps. This is unavoidable.

e4bf9ed8f0 gl/utils: Fix NDC conversion matrices for column-majorness
The matrices were converting the wrong values with non-diagonal-only matrices.
e.g. a typical yflip matrix in [-1,1]^3 such as
 1  0  0  0
 0 -1  0  0
 0  0  1  0
 0  0  0  1

Would have actually required a matrix like this in [0,1]^3
 1  0  0  0
 0 -1  0  0
 0  0  1  0
 0 -2  0  1

Which is
1. not consistent with our multiplication convention and would require
   transposing matrices or changing our multiplication order (from what is
   generally used on opengl matrix guides/tutorials).
2. Produces incorrect values when input with actual vertices accounting for
   the difference in multiplication order.  e.g. some vertices multiplied by
   the yflip matrix using vertex * yflip(== transpose(yflip) * vertex):

     vertex:       -> result:           expected:
     vec4(1,0,1,1) -> vec4(1,-2,1,1)    vec4(1,1,1,1)
     vec4(1,1,1,1) -> vec4(1,-3,1,1)    vec4(1,0,1,1)

With the updated values, we now get the expected values.

Includes a test for this behaviour and the example above

8467939538 rtpbasedepayload: condition the sending of gap events
The default implementation for packet loss handling previously
always sent a gap event.

While this is correct as long as we know the packet that was
lost was actually a media packet, with ULPFEC this becomes
a bit more complicated, as we do not know whether the packet
that was lost was a FEC packet, in which case it is better
to not actually send any gap events in the default implementation.

Some payloaders can be more clever about, for example VP8 can
use the picture-id, and the M and S bits to determine whether
the missing packet was inside an encoded frame or outside,
and thus whether if it was a media packet or a FEC packet,
which is why ulpfecdec still lets these lost events go through,
though stripping them of their seqnum, and appending a new
"might-have-been-fec" field to them.

This is all a bit terrible, but necessary to have ULPFEC
integrate properly with the rest of our RTP stack.

ae7a213628 valgrind suppressions: ignore XInitThreads leaks
As we load that symbol dynamically, valgrind gets confused
when it leaks and reports the leak against an unrelated library
and an unknown (??) symbol.

To address that, put the loading and calling of that symbol
in a separate function, and ignore any malloc leak happening
in that function.

It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.

For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.

For example with this patch, if an app includes the headers
  gst/gl/egl/gstglcontext_egl.h
  gst/gl/egl/gstgldisplay_egl.h
  gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

Also added a test: cd tests/check && make libs/gstglheaders.check

As a result we need to bind it on every draw in order to have the
correct state in the GL state machine.

7b42f26b80 applemedia/gl: Update code to use ARC
All code interacting with Objective-C objects should now use Automated
Reference Counting rather than manual memory management or Garbage
Collection. Because ARC prohibits C-structs from containing
references to Objective-C objects, all such fields are now typed
'gpointer'. Setting and gettings Objective-C fields on such a
struct now uses explicit __bridge_* calls to tell ARC about
object lifetimes.

Create our own instead as the default framebuffer may require special
fiddling (like having a visible window) to correctly display/be renderable.

gstgl doesn't undo/overwrite what GL state the examples are changing
anymore.  As such, the examples need to reset the GL state themselves
