c4216a693c v4l2codecs: mpeg2: Check that the decoder output formats 
This is to avoid exposing a decoder for which we don't support any
output format. This happens on platform using vendor formats or
not yet supported tiles formats.

7e875ddb2c v4l2codecs: mpeg2: Fix selected sizeimage 
Due to a copy paste bug, the bitdepth was never set and that was leading
to requesting sizeimage of 0. Previously that worked since the driver
would in that case pick a size for us. But now the we bumped the minimum
to 4KB, the driver happily allocate 4KB of bitstream which lead to
decoding error.

As MPEG2 have a fixed bitdeph of 8, use a define instead of the run-time
variable.

05458f05e0 v4l2codecs: vp9: Drop frames on non-keyframe format change 
V4L2 does not yet support this feature, this will skip over the
transition portion up to the next keyframe.

a6eb1e7782 v4l2codecs: Fix renegotiation 
If we hold the last reference to the allocator, leaving the device
streaming will cause an EBUSY error when trying to free the allocate
buffers.

d04fba93f8 v4l2codecs: vp9: Remove uneeded picture data 
The GstV4l2Request now holds a reference on the picture buffer and is
recounted already. This effectively removes usage of GRefCount which is only
available in GLib 2.58, while we support 2.56.

Fixes #910

83933b7772 v4l2codecs: h264: Properly set pic_num/frame_num 
The V4L2 uAPI uses pic_num for both PicNum and ShortTermPicNum. It also
doe the same for both FrameNum and LongTermFrameIdx. This change does
not change the fluster score, but fixed a visual corruption noticed
with some third party streams.

285695ee52 v4l2codecs: gstv4l2decoder: set minimum sizeimage 
Set minimum sizeimage such that there is enough space for any overhead
introduced by the codec.

Notably fix a vp9 issue in which a small image would not have a
bitstream buffer large enough to accomodate it.

120b96a974 v4l2codecs: gstv4l2codecsvp9dec: implement a render delay 
The v4l2 backend support delayed output for performance reasons.
It is then possible to use render delays to queue multiple requests
simultaneously, thus increasing performance.

8b932c105f v4l2codecs: Handle allocator creation failure 
If `VIDIOC_REQBUFS` doesn't return enough buffers the allocator creation
function can fail and return `NULL`. Handle this by generating an error
and returning instead of segfaulting.

3846b0563a v4l2codecs: Fix segfault when destroying non-detached allocator 
The GstV4l2CodecAllocator dispose function clears `self->decoder` but
the finalize function then tries to use it if the allocator has no been
detached yet.

Fix by detaching in the dispose function before we clear
`self->decoder`.

e322745763 codecs: h264decoder: Use GstFlowReturn everywhere 
boolean return value is not sufficient for representing the reason
of error in most cases. For instance, any errors around new_sequence()
would mean negotiation error, not just *ERROR*.
And some subclasses will allocate buffer/memory/surface on new_picture()
but it could be failed because of expected error, likely flushing
