This is basically a frame counter provided by the driver and it's
advancing at the speed of the HDMI/SDI input. Having this available on
each buffer allows to know what constant-framerate-based timestamp each
frame is corresponding to and can be used e.g. to write out files
accordingly without having the local pipeline clock timestamps used.

This reverts commit 6d256d9908.
It was configuring the period/buffer size in a way that often causes
drop-outs or complete underruns. Needs further investigation.

segsize should be based on latency-time, and must be a multiple of the
frame size. segtotal should be based on buffer-time and segsize.
This prevents errors caused by outputting buffers that are not a
multiple of the frame size, and actually makes the buffer-time and
latency-time properties do what they're supposed to do.

cc1: all warnings being treated as errors
Avfvideosrc represents an iphone camera or, on mac, a screencapture session.
The old API allowed you to select an input device by device index only. The new
API adds the ability to select the position (front or back facing) and
device-type (wide angle, telephoto, etc.). Furthermore, you can now specify
the orientation (portrait, landscape, etc.) of the videostream.

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.

It was previously possible for videotexturecache to be finalized before all of
its textures. Finalizing outstanding textures in this circumstance leads
to a crash. This patch ensure resources are freed in the proper order.

This seems to happen sometimes on some hardware, and is not really
critical as long as the scheduling of the normal frames works fine.
Only post a warning message for this case.
Overriding the pad query function completely overrides all the default
query handling implemented in basesrc, including caps etc. The correct
thing to do is just override the basesrc query vfunc and then chain up
for the queries we don't handle.
The cached texture was treated as user_data passed to GstGLBaseMemory
and freed with a GDestroyNotify function. However, this data must
be treated specially: it must be destroyed in the GL thread.

Enforce exactly the same raw video format on both sides, include a
videoconvert and queue before the video sink and make the shm area a
little bit bigger so that things don't get stuck.
and error out here already otherwise. We currently don't support
reconfiguration here and it can't happen really either unless the auto
mode is selected.
