The VideoLAN Forums

Hi,
I'm using vlc callbacks to get decoded audio/video frames and give them to a Decklink card.
I do not use timestamps, I use the synchronous playback APIs of the DekLink, which play audio samples/video frames as soon as they are called.
The only problem is that the audio starts 2 seconds before video.
I can solve the problem setting VLC to delay the audio 2 seconds, but I'd like a better solution.
Is there a way to tell vlc to synchronize audio/video callbacks?
Thanks for any help

Did you try VLC 2.1.0 and decklink output modules?

Ok, I'll try the decklink output module, but I wonder if the audio/video callback apis will be called anyway. As I need to overlay some graphics before sending the frame to the decklink card.
