Nothing to worry about here: you're disconnecting so the audio will also
stop.

This is completely unrelated to the audio playback and can safely be
ignored.

I have added this to the FAQ:
https://github.com/Xpra-org/xpra/commit/3ee7856363071b4638548b68a0cda8f5245fc72a

[winswitch] Error on disconect

2021-07-09 Thread xpra--- via shifter-users 



Getting the following error when disconnecting from a XPRA server


2021-07-06 23:25:19,020 audio playback stopping
/usr/lib/python3/dist-packages/gi/overrides/Gtk.py:1632: Warning:  
g_object_ref: assertion 'G_IS_OBJECT (object)' failed

  return _Gtk_main(*args, **kwargs)

Thats the last two lines of the log.

Audio playback does work from the server, but get this on any disconnect.

XPRA 4.02rc0 from XPRA repos, *buntu 20.04.2 on server and clients.

Thanks!

I think someone hit this error before, but I can't remember the details.
This is a toolchain problem, you will need to get someone from Odroid to
help you here. This looks relevant:
https://bugs.launchpad.net/ubuntu/+source/gcc-4.4/+bug/503448

Or just disable the ffmpeg based codecs (and maybe others too):
./setup.py --without-dec_avcodec2 --without-csc_swcale --without-enc_ffmpeg

You need the libavformat development headers and pkg-config file.

Hmm, yet another strange build problem on arm. I'm not sure why you have
a static library in /usr/local...
And I'm not going to recommend that you try to fix it because it's very
likely that the libav version is going to be too old anyway.
So the best course of action is probably to just build with:
./setup.py build --without-dev_avcodec2 --without-csc_swscale
And see where that gets you.
Hopefully you won't have to turn off too many things to get a working build.

Ubuntu Trusty will be supported in the next release so this is
definitely possible.
With trunk, unless you build against private ffmpeg headers as per:
http://xpra.org/trac/ticket/1256
you may need to build "--without-csc_swcale".
The v0.17.x branch may require more patching still and is not supported
with trusty.

Try with this changeset for older versions of Cython:
http://xpra.org/trac/changeset/13488
You may also need to apply this patch for building trunk with an old

The problem comes from your "xvfb" option in xpra.conf.
It looks to me like the package is pointing to a suid Xorg binary
("elevate privileges"), and this won't work. For more details see:
http://xpra.org/trac/wiki/Xdummy
Please contact the arch packager for help on this as I have no idea what
arch should be using / doing here.

There are a number of other issues shown as warnings:
* the x265 codec should probably not be built, or if built - the
dependency should be required
* same for pyopencl
* running without lzo or lz4 gives very poor performance
* you should have pygtkglext installed (for opengl accelerated client
rendering)
