hello,
I'm playing some videos tonight and was planning on using my pure:dyne
laptop to do so. However, though my projector screen is working fine (its a
DIY LCD monitor on overhead projector) when I try to play a video in VLC or
the GNOME movie player, it just stays black. The video plays on my laptop
screen but not the other. When I use AVIdemux it will play, but that isn't
really a very elegant option, and I can't go fullscreen it seems.
This isn't really a pure:dyne question I suppose, more general Linux, but
everyone here has been so helpful I thought I'd ask. I might figure it out
myself, but I've got less than 8 hours til showtime and thought I'd pool my
resources.
The problem is not all drivers/hardware supports video overlay on two
screens, and afaik there's no standard way to configure which screen you
want. Not really a Linux-specific problem either, I've heard users of
other operating systems complaining of the same thing. The workaround I
usually use is:
mplayer -vo x11 myvideofile.ogv
This won't be hardware accelerated like the default xv video out, but it
should at least display something. You might find you need to add
options for software scaling too, if it displays too small or at the
wrong aspect ratio. For full screen 800x600 you might use:
mplayer -vo x11 -fs -vf scale=w=800:h=600 myvideofile.ogv
Hope this helps to some degree, maybe there are options in the other
players to adjust overlay or acceleration settings as well.
