c0ee4e0ac2 avdevice/decklink_dec: add option to align capture start time 
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.

as it's the case when remuxing AV1 streams from mp4, so ignore it and
write the correct value based on codec ID instead.
