Hi all!
@ywlke
I can confirm audio cuts regularly and I have been debugging a little bit to find out the cause. In some situations, audio scheduling exceeds the available card internal memory and so it rejects the audio coming in. One simple solution is to check whether there is too much audio already scheduled and wait until Decklink plays part of it. Another solution is to upgrade Decklink's drivers to the latest version. I do not know if it was a Decklink's driver bug but it is now working fine with the latest drivers.
I also tried to compile (mingw32) the code from this ticket
https://trac.videolan.org/vlc/ticket/12678
but the video is not scaling. Is there some code missing to handle video scaling?
Thanks guys!
