video only in the primary screen

[Nicolò Chieffo]

Binary package hint: totem

I'm using a double screen config, through the new xrandr protocol. laptop LCD + external CRT.
Totem uses overlay to show the video, and this causes the fact that the image is only displayed in the primary screen, while in the secondary I get a black window.
I think that totem should force to not use overlay on the secondary screen. is it possible?

totem-gstreamer 2.19.90-0ubuntu3

The overlay can only be sourced to one crtc at a time (it does not draw directly to the framebuffer like 3D does). To switch which crtc the overlay is displayed on in clone mode, use an app like xvattr to change the value of the XV_CRTC attribute. For dualhead modes, the overlay will automatically follow the video window from head to head.

Don't you think this is a limitation?

[Daniel Stone (daniels)]

Yes, it's a limitation, but the hardware literally can't do it. It's not a driver issue.

[Nicolò Chieffo (yelo3)]

Ok, so to which package should I file this bug?

[Daniel Stone (daniels)]

Your video player should be able to force software colourspace conversion, instead of using the overlay.

[Nicolò Chieffo (yelo3)]

I am using totem-gstreamer. Can it do this?
And is colourspace conversion more "heavy" for the CPU, than overlay?

[Daniel Stone (daniels)]

Yes, Totem can do it, but it's very slow.

[Nicolò Chieffo (yelo3)]

All right. does it mean that I should file a bug to totem? and could you please tell me how to enable colourspace conversion in totem? thanks!

Thank you for your bug. I'm not sure if that's possible. Do you get the same issue with other xine for example?

[Nicolò Chieffo (yelo3)]

If I'm not wrong, this happens with kaffeine which is xine!

[Sebastien Bacher (seb128)]

That's not really clear, do you get the bug or the correct behaviour using it? What about xineui?

[Nicolò Chieffo (yelo3)]

I get the bug, even using xineui.

[Sebastien Bacher (seb128)]

Could you give the bug number of this comment?

[Nicolò Chieffo (yelo3)]

sure, http://bugs.freedesktop.org/show_bug.cgi?id=12281
it is not totem upstream, but xorg radeon upstream (and they tell it's
not their fault, because the hardware can't do overlay on more than
one screen)
I wonder how windows xp handles this

[Pedro Villavicencio (pedro)]

Did you reported this bug to the totem developers? For instructions on how to do it you can read: https://wiki.ubuntu.com/Bugs/Upstream/GNOME ; setting this as incomplete until it gets forwarded upstream, thanks.

[Sebastien Bacher (seb128)]

the comments indicate that's an hardware or driver limitation and not a bug, closing this task, feel free to open a new bug against the driver if you still get the issue though
