RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 5 Cole Robinson 2017-03-17 16:41:41 UTC 
For issues like this, please also check if virt-viewer reproduces the issue. If so, it's likely a spice issue. If virt-viewer works and virt-manager fails, probably virt-manager specific.

yes, only virt-manager fails. i didn't describe it clearly.
Comment 7 Pavel Hrdina 2017-03-24 16:51:25 UTC 
This is most likely spice-gtk issue even though virt-viewer is not affected by the updated.

If you run virt-manager --debug you can see that there is a spice warning:

  (virt-manager:29969): Spice-WARNING **: channel-display-gst.c:303:create_pipeline: GStreamer error: no element "avdec_h264"

and the same warning is printed if you run virt-viewer:

  (virt-viewer:30071): Spice-WARNING **: channel-display-gst.c:303:create_pipeline: GStreamer error: no element "avdec_h264"

The rebase to 0.33 version add a new build requirements for gstreamer1 however there is no gstreamer1-libav on RHEL and it probably breaks virt-manager because if I compile spice-gtk witout gstreamer virt-manager works correctly.

Even RPM compilation prints a warning about it:

configure: WARNING: The avdec_h264 GStreamer element(s) are missing. You should be able to find them in the gstreamer-libav 1.0 package.

configure: WARNING: The GStreamer video decoder can be built but may not work.
Comment 8 Pavel Grunt 2017-03-24 17:56:09 UTC 
interesting, I don't see how gstreamer can affect it. I can do a scratchbuild

(it is just an optional runtime stuff for video streaming decompression and these warnings should rather be debugs )
Comment 11 Pavel Grunt 2017-03-27 08:39:48 UTC 
It is related to the gtk version used during the build.

The working build mentioned in the comment 7 uses gtk 3.22 while the original build uses gtk 3.14

gstreamer addition is unrelated to the issue
