Subject: Sync new GStreamer element to parent state
X-Git-Url: https://git.stderr.nl/gitweb?p=projects%2Fchimara%2Fchimara.git;a=commitdiff_plain;h=9e5621c12a6c21c24a5b1e7829a9f37a50aca389

Sync new GStreamer element to parent state

In GStreamer 1.0, when adding a new element to the pipeline in a signal
handler, its state has to be synced to the pipeline's state, because the
handler could be called in the middle of a state change which would
cause the state change to hang.

This was supposed to be done in GStreamer 0.10 too, but it never caused
any problems.
