Hello

Thanks for this wonderful application!
There is a just one thing that is missing to complete my streaming solution.
So far I'm not able to set the audio-channel dynamically.

The global option works fine:
> vlc dvd:///home/dvd4/Antz/VIDEO_TS@1:1 --audio-channel=4

But the playlist option shows no effect at all:
> vlc dvd:///home/dvd4/Antz/VIDEO_TS@1:1 :audio-channel=4

Because I stream my DVD collection via VLC with a .m3u playlist I need to set the audio-channel (language) on playlist item base.

I tried this with VLC 0.7.1/Redhat Fedora1 and VLC 0.7.2/OSX 10.3.4.

Any hints?

Hello

To sad there is no reply at all

However I tried this again with the OSX version 0.8.0-test2 Janus.

The situation is even more strange.

./vlc -vvv dvdread:///home/dvd4/antz/VIDEO_TS@2:2-99:99 :audio-channel=3

Results in having to items in the playlist. One for the standard part of the mrl, one for the option!
Playing the first item shows that the correct audio-channel has been choosen.

Doing this by GUI dosn't work at all:

By removing the option this mrl plays again.
Opening this mrl via a playlist shows at least the same behavior.

Is this a bug or has the syntax for [:option] changed?

Thanks

This is a problem with how OSX works.
The only way to have OSX open files trough drag and drop is to have it open files. And unfortunatly this is implemented in a way that reads the commandline. Therefore both VLC and OSX read the commandline.

Resulting in duplicates. Not really anything that can be done about it, without breaking other support.

BTW. i'll see about audio-channel.
You have to realise that a lot of the -- options aren't capable of : yet. Even more, some of these options cannot be set at all as playlist item specific. I'll see if i can convert this particular one for you.

It should be working if you use an m3u file.
Something like:

#EXTM3U
#EXTVLCOPT:audio-channel=4
dvdread:///home/dvd4/antz/VIDEO_TS@2:2-99:99
#EXTVLCOPT:audio-channel=2
dvdread:///home/dvd4/antz/VIDEO_TS@2:2-99:99

Wow, thanks for your fast replies

#EXTVLCOPT works fine with the OSX version 0.8.0-test2 Janus.
:audio-channel and as well spu-channel can be set, great work guys!

I tried this with V0.7.2 Fedora and OSX too. But with these versions #EXTVLCOPT shows no effect.

I will verify this with V0.8.0-test2 on Fedora as soon as I find the time to build a binary. Rain has been annouced for next weekend anyway...

Again thanks for your help and for this great software
Emil

Hello

It was raining last weekend therefore I got my vlc-vnc fedora binary.
Yes, EXTVLCOPT works fine on fedora too!

But it took me some time to figure out, that I had to disable the following option:
# Enable streaming of all ES (boolean)
sout-all=1

Is there a reason behind this?
For me it makes sense to have all audio and spu channels streamed to a client and have also pre-selected the preferred ones via EXTVLCOPT.

However the existing functionality was good enough to complete my DVD-Streamer

Thanks a lot
Emil
