PyGIWarning: Gst was imported without specifying a version first #1181

Closed totaam closed 8 years ago

Issue migrated from trac ticket # 1181

component: server | priority: major | resolution: invalid

2016-04-20 18:08:25: urzds created the issue

When starting an Xpra server, I see the following warning:

sys:1: PyGIWarning: Gst was imported without specifying a version first. Use gi.require_version('Gst', '1.0') before import to ensure that the right version gets loaded.

The only location where we import the gstreamer 1.x bindings (aka "Gst") in the whole source tree is found here: [/browser/xpra/tags/v0.17.x/src/xpra/sound/gstreamer_util.py#L224] and looks like this:

    import gi
    log("import_gst1() gi=%s", gi)
    gi.require_version('Gst', '1.0')
    from gi.repository import Gst           #@UnresolvedImport
    log("import_gst1() Gst=%s", Gst)

And I have never seen this warning since the require_version line has been added a long time ago.

What distro and version are you running on? Maybe you want to run with -d sound,gstreamer or even -d all to find out where this is happening.

Full Xpra output [[BR]] I would need the debug output to figure out when this is firing. Or better yet, you can just run xpra/sound/gstreamer_util.py -v, it will probably fire the warning and show that it is bogus. Maybe a rawhide bug.

BTW, for a cleaner server startup:

  • Warning: webcam forwarding is disabled can be avoided with --webcam=no or by loading the kernel module
  • Error: lpinfo command failed to run... can be avoided with --printing=no or adding the commands and permissions
  • OpenCL Error:... Error: no devices found error message will look quite a bit cleaner as of r12450

Closing as invalid: this warning is bogus, it shows up straight after import_gst1 which does the required version call. Also it doesn't fire on any other distro, and they all have the same checks - which is why that check is there in the first place.
