I want to Open Network Stream with an MPEG2 stream that I know has multiple programs. I can do it as a 2 step process by menu Media - Open Network Stream and then menu Playback - Program to select program. Is there a syntax during Open Network Stream to specify the program number at the same time? And can this be accomplished via command line also? Thank you.

:program=xx

:program=xx

I need to know too. I play from streaming such as :

udp://@227.20.10.40program=02 ====> open program number 2. is it correct?

thanks

no, Show more options

:program=xx

note: my stream have 10 programs(channel) . How to write code to select program or channel on stream?

thanks

udp://@227.20.10.40program=02
This does not work in the Open Network Stream box for URL. But it seems like it should work.
If you put :program=02 in the Show more options, Edit Options box then that works. But that is a more painful 2 step process.

From a Command Prompt this works:
vlc.exe udp://@227.20.10.40:1234 :program=02
Note that you have to have a space before the :program=02
But in the Open Network Stream box for URL it will not allow you to have a space!

udp://@227.20.10.40::program=02
This used to work in the Open Network Stream box for URL but in recent versions has stopped.
We have tried all iterations of program= and nothing seems to work.
What is the new correct format for selecting a second program?
