problem : "display is not visible"

[yangranger]

Hi,

I use libvlc-qt in my program, and it works on a pc but it doesn't on another.
this program is a client to a H264 stream.
I think it's not a libvlc developping problem but a "standard vlc mode" so I posted it here.

here is the debug of the problem

I don't understand why the display works on one of the two PCs but not on the other.


thank you

Hi

No data received from the network.

this is when I stopped the test, (when I realize it will not work)

this means I receive a normal stream ; I can see this error "error while decodind" on the working other client, but it works well on the other client.

[Sébastien Escudier]

maybe you have too much packet lost, and vlc can't decode the pictures.

my first post was not clear, I mean, I don't understand why in these lines, my display is not visible.

[Rémi Denis-Courmont]

That message is coming from the X server. Normally, it means the entire surface of the window is obscured by other windows.

[yangranger]

it's weird because I use the same sources, and i don't launch any window manager.
there is only the application (which worked on another pc) in the .xinitrc . it is launched directly by X server, no kde no gnome....
