When trying to play audio using wx.MediaCtrl in the Demo or otherwise on Linux Mint 18.1 with wxPython Classic 3.0.2 an error comes up stating,
“Could not initialise AV output”
wx.Media is installed plus gstreamer and required plugins. Also, the Linux app, xPlayer, which also uses gstreamer will play audio so the issue must be with wxWidgets or wxPython.
Any suggestions?
I doubt that anyone will fix anything on Classic anymore.
I would suggest to try with wxPython 4.0 and maybe even on Python 3.
Have a look at the download page about binary installation: wxPython Downloads | wxPython
(be aware that "pip" proabably will install for Python 2; you may want to use "python3 -mpip" instead)
If it still fails, then bug reporting makes sense....

Dietmar

Is that EXACTLY what it said? Because that message does not appear in
the wxWidgets source code. The Unix wxMediaCtrl source has two
instances of "Could not initialize GStreamer", but nothing about "AV
output", and indeed no British spellings of "initialise".

Sorry, the error message said “XV output” instead of “AV Output.” I misstyped. Attached is a screenshot.
Also, this issue was brought up on the wxWidgets forum last year here,
https://forums.wxwidgets.org/viewtopic.php?t=43791
MediaCtrl used to work well on Linux with earlier version of wxPython, but this one doesn’t. Seems like it may be a missing driver or plugin, but I can’t tell.
By the way Phoenix is not an option right now. I must use Classic until our app can be upgraded for Phoenix.
Thanks,

Did you build wxPython Classic yourself, or are you using the Linux Mint distribution packages?

I’m using the Mint packages which are really the Ubuntu packages.

OK. I can reproduce this on Debian Unstable as well, and in wxWidgets, so it's not a wxPython issue per se. I'll look into it.

OK, I do definitely see the problem on a VM but not on a bare-metal Ubuntu 16.04. What happens when your users on bare metal run 'xvinfo'?

Scott,
Thanks very much for your help.
I got a chance to install Linux Mint bare-metal and saw that the error was not the same. The error there was a plugin was not loaded. (It seems the repositories have discontinued the gstreamer0.10 plugins expecting apps to use the 1.0 version instead. Fortunately, the gstreamer1.0 plugins will work. From what I gather, wx still uses 0.10, so the plugins must still be compatible).
Anyway, this is the first instance I have had where a VM failed.
Thanks again,
Tim

It depends on which version of Linux Mint you're using (really which Ubuntu version it's based on) whether gstreamer 1.0 is supported in wx. But yes, the version you're using must be supporting gstreamer 1.0.
