LUA interface problem

[johney_red]

Hi everyone,
I try to make my test1.lua script, which I call from shell, but it doesn't work. I first rise VLC through shell from python script:

Code: Select all

... // Only start VLC p = subprocess.Popen([path_to_VLC,"--fullscreen","--one-instance","-v","--verbose=2"]) // - work //and then put some video to playlist p = subprocess.Popen([path_to_VLC,"--fullscreen","--started-from-file","--playlist-enqueue","D:/Filmovi/a.avi" ]) // - work //at last, I want to control video with my lua script, but next line doesn't produce any output, no video, no error... nothing p = subprocess.Popen([path_to_VLC,"-I","lua","--lua-intf","test1","--lua-config","test1={command='plp'}"]) // - doesn't work ....

test1.lua:

Code: Select all

comm = config.command if comm == "plp" then playlist.play() --try this way vlc.playlist.play() --try this way end

Every proposition is welcome , Best Regards

The script must be in the share/lua/intf/ directory to be taken into account.
Looking at the vlc logs can help you too.

Hello Ivorie
Thank you for your time to get involved. My lua script is on "C:\VLC\vlc-1.1.1-win32\vlc-1.1.1\lua\intf\test1.lua" path, and I have setup log into "C:\VLC\vlc-1.1.1-win32\vlc-1.1.1\lvlc-log.txt" file as text, but i do not get any log into it. For now, when I start VLC i turn on Messages window (Ctrl+M) with verbosity level 2,and I do get main debug output when I edit playlist form shell, but line with call to lua doesn't produce any output, and that is problem. I dont know if VLC see script, or the script is fault..

This all I get in Messages window:

Code: Select all

main debug: adding item `Filmovi/a.avi' ( file:///D:/Filmovi%2Fa.avi ) main debug: rebuilding array of current - root Playlist main debug: rebuild done - 1 items, index -1 main debug: Creating an input for 'Filmovi/a.avi' main debug: no fetch required for (null) (art currently (null)) main debug: adding item `Filmovi/For_The_Birds.avi' ( file:///D:/Filmovi%2FFor_The_Birds.avi ) main debug: Creating an input for 'Filmovi/For_The_Birds.avi' main debug: rebuilding array of current - root Playlist main debug: rebuild done - 2 items, index -1 main debug: no fetch required for (null) (art currently (null)) main debug: adding item `Filmovi/The_Chubbchubbs!.avi' ( file:///D:/Filmovi%2FThe_Chubbchubbs%21.avi ) main debug: rebuilding array of current - root Playlist main debug: rebuild done - 3 items, index -1 main debug: Creating an input for 'Filmovi/The_Chubbchubbs!.avi' main debug: adding item `Filmovi/b.avi' ( file:///D:/Filmovi%2Fb.avi ) main debug: no fetch required for (null) (art currently (null)) main debug: Creating an input for 'Filmovi/b.avi' main debug: no fetch required for (null) (art currently (null))

Any idea for solution?

Best Regards

Could you send vlc directly from the command line ? This way you might see the debug output. vlc -I lua --lua-intf test1 --extraintf logger

[johney_red]

Hmmm.. i already try to do complete process in command line with parameter '--extraintf logger' without python and guess what, no output again... yea, it is strange somehow.. but I have found way to get output with python.It is interesting that there I can get output true process connection, when I call :

Code: Select all

p = subprocess.Popen([path_to_VLC,"--fullscreen","--one-instance","-vv","--verbose=2"],stdout=subprocess.PIPE,stderr=subprocess.PIPE) stdout_value , stderr_value = p.communicate('through stdin to stdout')

and output for every line of my little script:

just start VLC with empty playlist:
p = subprocess.Popen([path_to_VLC,"--fullscreen","--one-instance","-vv","--verbose=2"],stdout=subprocess.PIPE,stderr=subprocess.PIPE)
log:

Code: Select all

Any idea what is happening? Or we may call Chuck Norris to help us

I will have to try to use a custom lua interface tonight (I can't test it here !)

[johney_red]

Same results with 1.1.4 version of VLC. Ivorie, do you have some idea?

[ivoire]

I don't have any problem creating a custom interface and launching it with

Code: Select all

./vlc -I luaintf --lua-intf essai

The lua interface is just a small script in share/lua/intf/essai.lua which contains:

Code: Select all

vlc.msg.err("essai")

[johney_red]

I see that you use Linux... i test this on Win 7 and VLC get my command, but nothing happened, i test it on another one PC to, same result.. lua just do not give any response. If I put something like :

../VLC.exe -I lua --lua-intf test1 --lua-config test1={command='plp'} //bad syntax

../VLC.exe -I --lua --lua-intf test1 --lua-config test1={command='plp'} //good syntax

I do get mistake, command is not recognized... so it is some mistake in VLC when he don't response on regular command..
I have installed "LuaForWindows_v5.1.4-40" is there mistake?

Best Regards

[johney_red]

Nope... I m sorry for bad information, I do not get any mistake for bad command with lua interface... I'm gonna test it until I die...

[ivoire]

Just try the command line I gave you and a really simple lua file like the one I gave you. Maybe the file is just in the wrong directory.

[jeanfirst]

Don't die before you read my reply.

I tried something similar:

Code: Select all

VLC = ['/Applications/VLC.app/Contents/MacOS/VLC', '-I', 'macosx', '--extraintf=lua', '--lua-intf=rc', '--lua-config="rc={host=\'localhost:4222\'}"', '/Users/me/Desktop/image.jpg'] vlc = subprocess.Popen(VLC)

And it always gave me the *console, but not the luarc!

So I chaged it to:

Code: Select all

VLC = '/Applications/VLC.app/Contents/MacOS/VLC -I macosx --extraintf=lua --lua-intf=rc --lua-config="rc={host=\'localhost:4222\'}" /Users/me/Desktop/image.jpg' vlc = subprocess.Popen(VLC,shell=True)

Which works the way it should.

[ivoire]

I think python is doing something strange here but I don't see what can be donne the wrong way.

Could you try vlc -I lua --lua-config=... --extraintf=logger.

A file called vlc-log.txt will be created.
