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.

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

Configure the display mode when setting the negotiated caps instead of
during showing the first frame.
A framebuffer is required to set the mode. Allocate a buffer object
according to the negotiated caps and use it to set the mode. This buffer
object cannot be freed until another page flip happened on the crtc
(i.e., until the first frame is rendered).

The force-modesetting parameter forces the kmssink to ignore already
configured display modes, to configure the display mode itself and use
the base plane for output.
https://bugzilla.gnome.org/show_bug.cgi?id=773473
If the input buffers have a different size than the display, the frames
would have to be scaled or positioned on the display. The kmssink cannot
decide which behaviour would be appropriate for which use case.
In order to avoid scaling or positioning of the input stream, allow only
the supported connector resolutions in the sink caps.

Displays usually support multiple modes. Therefore, the kmssink should
not only support the preferred mode, but any mode that is supported by
the display.
https://bugzilla.gnome.org/show_bug.cgi?id=773473
The kmssink assumed that the mode was already set by another application
and used an overlay plane for displaying the frames.
Use the preferred mode of the monitor and render to the base plane if
the crtc does not have a valid mode.

First of all, all the HD and UHD modes should be top-field-first, as
also returned by the Decklink mode iterator API.
Then we should include the caps field "field-order" in the caps of the
source (not the sink due to negotiation problems with optional fields).
And finally we should set the TFF flag on interlaced buffers that are
top-field-first.
On some hardware the first few frames are bogus and not very useful.
Their timestamps are off, they have no timecodes, or there are spurious
black frames / no-signal frames. After a few frames this stabilizes
though.
https://bugzilla.gnome.org/show_bug.cgi?id=774850
Based on this we calculate the actual capture time, which should get us
rid of any capturing jitter by averaging it out.
Also add a output-stream-time property which forces the elements to
output the stream time directly instead of doing any conversion to the
pipeline clock. Use with care.
https://bugzilla.gnome.org/show_bug.cgi?id=774850
The hardware timestamps have no relation to when frames were produced,
only when frames arrived somewhere in the hardware. Especially there is
no guarantee that audio and video will have the same hardware timestamps
although they belong together, and even more important: the rate with
which the hardware timestamps increase is completely unrelated to the
rate with which the frames are captured!
As such we can as well use the pipeline clock directly and stop doing
complicated calculations. Also as a side effect this allows now running
without any pipeline clock, by directly making use of the stream times
as reported by the driver.

libkms should not be used, because it imposes limitations on the DRM
API, especially regarding bpp and stride. Instead the DRM IOCTL should
be used directly.
Switch from libkms to the IOCTL interface. Set bpp and height for
framebuffer allocation to properly handle planar video formats.

When a frame is found to not have an associated input source (cable
unplugged, wrong mode selected), an element warning will be issued. When
the next frame in the stream is found to have an input source selected

The default get_times() function of the base sink is just fine.
Remove the custom get_times() function, because the default function

Unfortunately this does not go through the normal state change
machinery, so we don't get notified about this in change_state().
However we need to stop scheduled playback, so that once PLAYING is
reached again we can start scheduled playback with the correct time.
Without this, flushing seeks in PLAYING will not work correctly:
decklinkvideosink will wait before showing the new frames for the amount
of time the pipeline was in PLAYING before.
Drawing is done via the GDI drawing functions. The cursor is
converted to a monochrome version before drawing. This is because
the GDI drawing functions seem to have undefined behavior with
cursor images including an alpha channel.
I could not find any other reliable way to draw these alpha
channel cursors without producing unwanted artifacts. These type
of cursors were introduced with Window Vista when run with it's
Aero theme.
Also adjust the cursor coordinates when capturing non-primary
screens via the "monitor" option.

Currently dx9screencapsrc prints a verbose warning in case the screen
index is out of range for the current number of detected monitors. This
value is then dropped.
However there is no initial indication (beside the console print) if it
worked or not. This may result in capturing an unwanted screen as it
would capture the last set index that was not rejected.
This patch sets the index regardless. Instead, the element throws an
error when it tries to run or getting caps for an invalid index.
