A couple of follow-up Qs:
Is auto-detection available for all Decklink devices?
No, but AFAIK it is for all devices which support SDI. Generally it's
the older analog capture devices which don't support it.
For those for which it is available, are there any edge cases in which
it sets inaccurate mode?
I don't trust the existing detection code enough to use it in
production. It often fails to detect and thus ffmpeg will exit at
startup.
Can this be fixed by simply increasing the timeout from 1 sec to 2
seconds?
Also, there are cases where it will misdetect 1080i59 as
1080p30 depending on the card. It's been on my TODO list for a while
to make that code more robust (I believe I know what most of the
issues are), but it hasn't been critical for any of my use cases.
Hmm, interesting... When you say the issue is card-dependant, does this
mean card _model_ dependant or that the issue can affect one card and not
the other with of the same model/fw?
Thanks,
Marton
