Module: gstreamer-sharp
Branch: master
Commit: 48a5bce6892d9db0be12f0c95f6ad2df4ffd1688
URL:    http://cgit.freedesktop.org/gstreamer/gstreamer-sharp/commit/?id=48a5bce6892d9db0be12f0c95f6ad2df4ffd1688

Fix the Gst.Task bindings

What still needs to be done is to add a way to set
a custom lock to the task, currently a newly created
task can only get a lock by making it a pad task.
