[FFmpeg-devel] Up to Date DeckLink Support broken in FFMPEG

[FFmpeg-devel] Up to Date DeckLink Support broken in FFMPEG

[ffmpeg]

Hi Folks

It seems like the current decklink code in FFMPEG is no longer fully compatible with the latest Decklink drivers
The behaviour seen is that output via DeckLink starts OK but very quickly stalls. Apparently its related to the callbacks.
I believe this broken with BMD drivers 13.3 and later

Has anyone here already fixed the FFMPEG code to work again ?   

If no-one has attempted this fix, I will give it a go, but if someone is ahead of me please let me know

Thanks !!!

Mark.

Feel free to take a look. The last change to the decklink code in FFmpeg 
was authored last april (not counting minor one-line bugfixes and the 
like) and as far as I am aware nobody is currently working on that so 
you wouldn't be redoing someone else's work.
