Description Jan Schmidt 2008-05-27 12:18:33 UTC 
It used to be possible to close the current segment and open a new one with a  basesrc based element by sending a non-flushing seek to itself in the chain method.

Since around 0.10.15, this deadlocks due to changes in basesrc internal locking (it deadlocks on the live-lock) and makes it hard to implement a source element that supports autonomous output of a sequence of seamless segments.
Comment 1 Jan Schmidt 2008-06-04 22:07:19 UTC 
This has been broken since last year sometime -  and since noone complained, I doubt anyone else is relying on it, so I don't really think it's a blocker. It'd be nice to fix it at some point though.
Comment 2 Wim Taymans 2008-06-05 09:19:32 UTC 
We should probably add a method to basesrc to perform this functionality from the streaming thread.
Comment 3 Wim Taymans 2009-12-11 17:08:32 UTC 
Fixed with this commit.
