IPv6 <-> IPv4 mismatch when subscribing to multicast (upstream patch)
Last modified: 2014-02-05 17:22:34 EST
Description of problem:
There's a bug in glibc that causes gstreamer to fail when trying to use multicast address. A patch was created and it was fixed in glibc 2.35.3
It would be great if we could apply this patch to our current glibc.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. don't explicitly disable IPv6, and
2. from a terminal run
$ GST_DEBUG=*udpsink*:5 gst-launch-1.0 fakesrc ! udpsink host=188.8.131.52 port=1234
(gst-launch-1.0:26827): GLib-GIO-CRITICAL **:
g_socket_multicast_group_operation: assertion `g_inet_address_get_family
(group) == socket->priv->family' failed
Could not join multicast group: unknown reason
ERROR: pipeline doesn't want to preroll.
The pipeline should run.
More details can be found under the associated gstreamer and glibc bug reports
Note that I said glibc in the comments when I really meant glib2.
Also note that this only effects F18 as F19 and above are glib2 >= 2.35.2.
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '18'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 18's end of life.
Thank you for reporting this issue and we are sorry that we may not be
able to fix it before Fedora 18 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior to Fedora 18's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
