Subject: Re: [PD] how to use the vlc plugin in GEM?
To: drnn_1076@hotmail.com

hi,

you should select the VLC driver with the [driver vlc( message, then use the message [device $1( to open something (a file, a stream...)

but note 1 : $1 in device message should be a full path like the one you enter in VLC (ex : file://home/me/mavideo.avi or udp://@232.0.1.1:8200)

2 : vlc driver didn't know the resolution of the video, you should set it yourself with the [dimen width height( message

see attachment

I note that the vlc-videoplugin.pd is empty, this could be filed with some informations like above.

cheers

HI,

I just compiled the GEM-master from git. I want to stream what I have in VLC in GEM via to pix_video.
I'm in linux, opensuse 12.3, puredata vanilla 0.44.0, and GEM-master downloaded form git today.

However I'm not able to get it work. I'm puzzled. How does this work? I've tried the to send the message [device screen://( to [pix_video] but I've got nothing on the screen and the following message:

Cannot open '': 2, No such file or directory
v4l: failed opening device: 'screen://'
videoDC1394: no cameras found

Here is the output I've got when pix_video is running using the 04.video patch.

[pix_video]: backend #0='v4l2'    : v4l2 analog
[pix_video]: backend #1='v4l'    : v4l analog
[pix_video]: backend #2='dc1394'    : dc1394 iidc
[pix_video]: backend #3='vlc'    : vlc

When the fourth backend is hit 'vlc' I've got:

Cannot open '/dev/video3': 2, No such file or directory
v4l: failed opening device: '/dev/video3'
videoDC1394: no cameras found

This is the output when GEM starts:
