Request for adding audio track cmd in RC interface

[vlcrcuser]

It's nice that vlc.exe can change the audio track and audio mode in RC interface module.

[dionoea]

I'll try to add that this week end. (try == if i remember)

Thanks in advance.
Let me know when you're ready, I'll be happy to test them.

[dionoea]

http://trac.videolan.org/vlc/changeset/16350 adds the "atrack", "vtrack" and "strack" commands. The other command you were looking for is "achan" (unless you meant something else when talking about audio mode) and is already available.
The should be include in tomorrow's nightly builds.

Tell me if they work as intended.

Best regards,

Hi,

It's seem to me that's the new atrack cmd for RC interface is working properly as expected. However, the new vlc.exe-20060827-318 version having problem when start the video screen, therefore I could not test the vtrack and strack cmds.

It seem to me the video problem only occurs on the ATI video cards

try changing the video output module back to DirectDraw in the preferences.

Video screen works, also vtrack cmd. I don't have any file with 2 subtitles therefore, I couldn't check strack yet. I'll try with some DVD movie that have 2 subtitles and let you know the status of strack command.

My suggestion: when VLC response any command to the host, it should return the current cmd + value. This make the host handles the response easier in multi-thread apps.
Example

Host ----------------- vlc response --------------- current vlc response

get_time ----------- get_time=10 --------------- 10
is_playing ----------- is_playing=0/1 ------------- 0/1

Some current cmds response with cmd + value, ex. atrack, adev...

Have you plan to add the sound effect/equalizer cmd for RC interface ?

[dionoea]

I'll see what i can do about returning commands' names with the values (it'll most likely break other people's setups so i'm not sure that it's a good idea to change current behavior).

About the equalizer, support for changing it through the rc interface isn't planed, but it shouldn't be hard to do. (Best thing would be to just list the whole bunch of commands which you need)

I understood your concern. How's about add a switch to the code, default response=current response., New response=Cmd+Value(s). It isn't importance, the current response cmds are fined to me. Again, It's just the suggestion for future cmds or If there is a change in RC interface module

About the equalizer, support for changing it through the rc interface isn't planed, but it shouldn't be hard to do. (Best thing would be to just list the whole bunch of commands which you need)

Actually, I don't need the equalize cmds at all but others may needed. So It's up to you .
