Can't get 'screen://' to work

Postby relaht » 06 Jan 2013 20:37

I am using this command:

Code: Select all

vlc screen://
it used to work, but vlc 2.0.5 on my new MacBookPro gives me this error (mountain lion)

Code: Select all

screen error: Core OpenGL failure: invalid fullscreen drawable main debug: no access_demux module matching "screen" could be loaded main debug: TIMER module_need() : 5,097 ms - Total 5,097 ms / 1 intvls (Avg 5,097 ms) main debug: creating access 'screen' location='', path='(null)' main debug: looking for access module: 0 candidates main debug: no access module matched "screen" main debug: TIMER module_need() : 0,082 ms - Total 0,082 ms / 1 intvls (Avg 0,082 ms) main error: open of `screen://' failed macosx debug: Found 1 capture devices main debug: finished input main debug: dead input main debug: changing item without a request (current 1/2) main debug: nothing to play main debug: TIMER input launching for 'screen://' : 653,169 ms - Total 653,169 ms / 1 intvls (Avg 653,169 ms) macosx debug: no optical media found
any ideas?

Is this on 10.7? If yes, this is the reason. VLC 2.0.x doesn't support screen capture on this OS. A re-written module will be part of VLC 2.1 and re-enable this feature again.

My MBP is running 10.8.2 (Mountain Lion)
Could this be the reason too?

Yes, I should have been more precise. It's about 10.7 and later.

Get a 2.1 nightly build to work-around this limitation.
