Description Michael Smith 2006-11-30 17:19:55 UTC
This patch changes it to:
 1) If we've received no-more-pads, getting caps on our sinks makes us finish
 2) otherwise, add success cases to the timeout (for formats like mpeg that can't send no-more-pads)

This makes it work for more cases.

(not proposing to break the freeze for this)

Better patch!

This patch doesn't race, unlike the previous one.

what's up with this?
Comment 4 Michael Smith 2007-03-06 09:58:14 UTC
I dunno, I guess a gst-python hacker should review it. Mr Hervey?

I still have it in my gst-cvs tree, and have been using it since I wrote it.

looks fine to me. Might want to talk to sebastien for race-related issues in discoverer, I think he has some patches too.
