Use specific port for output audio and video in streaming

[triplebit]

I use LibVlc.dll in my application.
I saw in the documentation that the audio output stream port may be set as different that the video.
Can they share the same output port?
What is the advantage of using specific port for each?

I assume you mean RTP output? RTP cannot deal with multiple concurrent sessions on the same port. To share port for audio and video, you need to multiplex (to MPEG-TS) first.

Thanks Remi
Ictually I use UDP with the same port for both.
Can I use specific ports for that also?
Is there any document that elaborates on that?
