[vlc-devel] How to using vlc submodule? both Video and Audio output in one plugin?

[Ocon 8866]

Hi Jean.

I've found the way to active both module:

$vlc filetoplay --vout decklinkoutput --aout decklinkoutput

but i'm having another problem. Cause Decklink SDK is not currently support
*WriteAudioSamplesSync* function. So only video works now.
I may change my plugin to use fifo file and let Decklink get data via *
ScheduleVideoFrame*.

Hope to release the plugin soon.
