a260426194 encoder: h264: submit SEI buffering_period() and picture_timing() messages for CBR mode
One buffering_period() SEI message shall be present in every IDR access unit
when NalHrdBpPresentFlag is inferred to be equal to 1. This is the case when we
use a non-CQP mode, e.g. CBR. In other words, when
nal_hrd_parameters_present_flag is set to 1.

One picture_timing() SEI messages shall be present in every access unit
if CpbDpbDelaysPresentFlag is equal to 1 or pic_struct_present_flag is equal to 1

2a2ecbe865 encoder: jpeg: Fix the packed header generation
This is a work-around to satisfy the va-intel-driver.
Normalize the quality factor and scale QM values (only for packed header
generation) similar to what VA-Intel driver is doing . Otherwise the
generated packed headers will be wrong, since the driver itself is
scaling the QM values using the normalized quality factor.

8dd93e9c8a decoder: h264: add support for missing first field.
Try to identify missing first fields too, thus disregarding any
intermediate gaps in frames. We also assume that we keep the same
field sequence, i.e. if previous frames were in top-field-first
(TFF) order, then so are subsequent frames.

Note that insertion of dummy first fields need to operate in two
steps: (i) create the original first field that the current field
will inherit from, and (ii) submit that field into the DPB prior
to initializing the current (other) field POC values but after any
reference flag was set. i.e. copy reference flags from the child
(other field) to the parent (first field).

efaadfc7c0 decoder: h264: add support for missing second field.
Interlaced H.264 video frames always have two fields to decode and
display. However, in some cases, e.g. packet loss, one of the field
can be missing. This perturbs the reference picture marking process,
whereby the number of references available in DPB no longer matches
the expected value.

This patch adds initial support for missing field within a decoded
frame. The current strategy taken is to find out the nearest field,
by POC value, and with the same parity.

6229ad4f7f decoder: h264: fix processing of EOSEQ NAL.
Fix decoding of end_of_seq() NAL unit so that to not submit the current
picture for decoding again. This is pretty vintage code that dates back
before the existing of the whole decoder units machinery.

One issue that could be arising if that code was kept is that we could
have submitted a picture, and subsequently a GstVideoCodec frame, twice.
Once without the decode_only flag set, and once with that flag set. The
end result is that the GstVideoDecoder would release the codec frame
twice, thus releasing stale data.

In short, the piece of code that is removed by this patch is for once
completely obsolete for a while, and secondly error-prone in corner
cases.

70eff01d36 wayland: sync() when destroy()
Before pushing a the new frame, the render() method calls sync() to flush the
pending frames. Nonetheless, the last pushed frame never gets rendered, leading
to a memory leak too.

This patch calls sync() in the destroy() to flush the pending frames before
destroying the window.

Also a is_cancelled flag is added. This flag tells to not flush the event
queue again since the method failed previously or were cancelled by the user.

522ec79d2e wayland: wl_display_dispatch_queue() can block forever.
wl_display_dispatch_queue() might prevent the pipeline from shutting
down. This can happen e.g. if the wayland compositor exits while the
pipeline is running.

This patch replaces it with these steps:

- With wl_display_prepare_read() all threads announce their intention
  to read.
- wl_display_read_events() is thread save. On threads reads, the other
  wait for it to finish.
- With wl_display_dispatch_queue_pending() each thread dispatches its
  own events.

wl_display_dispatch_queue_pending() was defined since wayland 1.0.2

c80951ada1 wayland: use a counter as sync flag
Wayland window has a pointer to the last pushed frame and use it to set the
flag for stopping the queue dispatch loop. This may lead to memory leaks,
since we are not keeping track of all the queued frames structures.

This patch removes the last pushed frame pointer and change the binary flag
for an atomic counter, keeping track of number of queued frames and use it for
the queue dispatch loop.

62c3888b76 wayland: decouple wl_buffer from frame
This patch takes out the wayland's buffer from the the frame structure. The
buffer is queued to wayland and destroyed in the "release" callback. The
frame is freed in the surface's "done" callback.

In this way a buffer may be leaked but not the whole frame structure.

- surface 'done' callback is used to throttle the rendering operation and to
  unallocate the frame, but not the buffer.
- buffer 'release' callback is used to destroy wl_buffer.

b5425da1de display: drm: fix race condition setting device type
There is a race condition where g_drm_device_type can be left set to
DRM_DEVICE_RENDERNODES when it shouldn't.

If thread 1 comes in and falls into the last else statement setting up both
RENDERNODES and LEGACY types. And begins to process the first type (RENDERNODES),
it sets g_drm_device_type = RENDERNODES.

Now when thread 2 comes in and sees g_drm_device_type is RENDERNODES, it queues
up that type to be tried but then encounters the lock and has to wait until the
first thread finishes. Once the lock is acquired it will then proceed to ONLY try
RENDERNODES and fail it. But it doesn't try LEGACY. And from then on, all future
attempts will only try RENDERNODES.

So to avoid this situation I have simply moved the acquisition of the lock higher
up in the attached patch.
