"found no video or audio data in input" for everything -- Debian

[lessbones]

hmm, i tried this with both env.sh and env.csh but no difference...

[Selur]

Strange,...
don't have much time today, but I compiled a new dev version (send you a link via pm) which allows to disable library loading by adding:

[General]
vsNoLibraries=true

to a misc.ini file (see: [INFO] *hidden* Hybrid options,... for where the misc.ini can be located)

thank you!

I'll check it out and report back in a little bit--

Now i'm getting


"qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb."


I know I've seen this before, but doesn't happen with the version of the binary that I just replaced...

[Selur]

No clue why the new binary would require something different, since it was build with the same libraries&co.
Have you read https://forum.selur.net/thread-1669.html and the connected threads? iirc the xcb problem was related to the used vnc solution.

In this case I haven't even been trying to launch it through a VNC, just from the command line, even without X11 forwarding (usually that looks like this with the binary from the downloads section:  

qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.)

with QT_DEBUG_PLUGINS=1 I'm getting:

Before it ever tries to connect to the X display...

I think this has something to do with a Qt version problem

[Selur]

Hybrid isn't meant to be used without a display so without any forwarding etc. it's not surprising that it doesn't work.
About the xcb issue, read the other thread. I think the users who had the issue before fixed it by using another vnc / remote desktop solution.

No, of course I realize it's not going to work without any forwarding-- generally I've been using Xpra and it's been working great... on the old binary.  I was just pointing out the differences between the two-- with the one from downloads I can get into the GUI with no problems using Xpra, or forwarding with "ssh -Y user@host" but with the new one it throws the xcb error, and it does so before ever trying to interact with the forwarding method.

I'll see if there's some way I can upgrade my Qt installation.
