DeckLink Mini Recorder is not working - for avconv it does not starts processing input.

bmdcapture returns error while trying to list cards supported modes:

Could not obtain the IDeckLinkOutput interface - result = 80000004

Command line arguments for input:

avconv -analyzeduration 0 -f bmd -video_mode 8 -instance 0 -audio_connection 2 -video_connection 4 -video_format 1

I seem to have the same problem. Did you end up finding a workable solution?

[orthatg]

I believe this is not actually an error, though not very clear either. The mini-recorders do not have any video outputs, so the message is simply saying that it couldn't find an ouput (because there are none).

[emptygalaxy]

It does give an error about not obtaining an output interface. However, it shouldn't because we are starting the capture functionality with bmdcapture (hence the recorder).
