If the packets returned by libvpx and our internal frame properties
queue get desynchronized for some reason (should not happen, but it is
not clear libvpx API guarantees this), we will keep adding to the queue
indefinitely and never remove anything.
Change the code to drain the queue even if timestamps do not match.
This AVFifo is used to propagate HDR metadata from input frames to
output packets, since libvpx does not allow passing through arbitrary
user data.
It will be extended to pass through other kinds of data in future
commits, so give it a more generic name.
It is not used, except to check whether the packet is valid before
writing HDR metadata to the packet in storeframe(). However, that check
serves no purpose, as the encoded packet is already treated as valid
higher up in this function.

it can start with <svg and can have multiple empty lines,
or start with <!-- include some comments,
but must first line if start with <?xml.

Due to refactoring, the ctx/cctx variables are never actually used
in ff_decklink_write_packet(), so just remove them.

The ff_decklink_write_packet() was always caching the last pts
received, to be used when calling StopScheduledPlayback(). However
because audio and video are on different timebases and the call to
StopScheduledPlayback() expects the video timebase, we'll end up
sending a weird value to the stop routine if the last packet
received contained audio.
Move the setting of last_pts to just be for the video stream.

The existing code assumed that the first frame received by the decklink
output would always be PTS zero. However if running in other timing
modes than the default of CBR, items such as frame dropping at the
beginning may result in starting at a non-zero PTS.
For example, in our setup because we discard probing data and run
with "-vsync 2" the first video frame scheduled to the decklink
output will have a PTS around 170. Scheduling frames too far into
the future will either fail or cause a backlog of frames scheduled
far enough into the future that the entire pipeline will stall.
Issue can be reproduced with the following command-line:
./ffmpeg -copyts -i foo.ts -f decklink -vcodec v210 -ac 2 'DeckLink Duo (4)'
Keep track of the PTS of the first frame received, so that when
we enable start playback we can provide that value to the decklink
driver.
Thanks to Marton Balint for review and suggestion to use
AV_NOPTS_VALUE rather than zero for the initial value.

As per 23003-5:2020, the rest of the bits are reserved, and thus
in the future they may be utilized for something else.
Quote:
format_flags is a field of flags that modify the default PCM sample format.
Undefined flags are reserved and shall be zero. The following flag is defined:
0x01 indicates little-endian format. If not present, big-endian format is used.
