Capturing VANC data from DeckLink Mini Recorder

PostFri May 05, 2017 12:32 am

I use a DeckLink card to capture live streaming video for processing by FFmpeg. But at the same time, I would like to capture incoming VANC data via the DeckLink SDK. Attempts to do so, however, result in the error “Failed to enable video input” because it seems that FFmpeg has exclusive use of the DeckLink.

Is there a way to obtain the VANC data while simultaneously processing video through the card?

Hello Richard,

I understand that you are wondering whether it is possible to concurrently access a DeckLink interface from multiple applications.

I can confirm that it is not possible to concurrently use a DeckLink interface such as DeckLink Mini Recorder from multiple applications.

Hope this helps.
