Deprecate the option 'draw_bars' in favor of the new option 'signal_loss_action',
which controls the behavior when the input signal is not available
(including the behavior previously available through draw_bars).
The default behavior remains unchanged to be backwards compatible.
The new option is more flexible for extending now and in the future.
The new value 'repeat' repeats the last video frame.
This is useful for very short dropouts and was not available before.

Support decoding and embedding VANC packets delivered via SMPTE 2038
into the SDI output. We leverage an intermediate queue because
data packets are announced separately from video but we need to embed
the data into the video frame when it is output.
Note that this patch has some additional abstraction for data
streams in general as opposed to just SMPTE 2038 packets. This is
because subsequent patches will introduce support for other
data codecs.
Thanks to Marton Balint for review/feedback.

This option is useful for maintaining input synchronization across N
different hardware devices deployed for 'N-way' redundancy.
The system time of different hardware devices should be synchronized
with protocols such as NTP or PTP, before using this option.

If the user provides a valid timecode_format look for timecode of that
format in the capture and if found store it on the video avstream's
metadata.
Slightly modified by Marton Balint to capture per-frame timecode as well.

The decklink input pixel format can now be specified with the 'raw_format'
option. The -bm_v210 option is now deprecated.

As it is already written in the documentation, BMD DeckLink cards
are capable of capturing 2, 8 or 16 audio channels (for SDI Inputs).
Currently the value is hardcoded to 2. Introduces new option.

It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
