Mythfrontend crashes on "scene changes".

[j2@…]

(Trunk 27105, Ubuntu 10.04, PVR-500)

Right, this problem started appearing for me about two weeks back in trunk. I am honestly not sure which rev i was on before. (And I am not sure if it is possible to check?)

I mulled it out on the users-list, but didn't get any applicable feedback, so I decided to give it a trac-run.

The problem now is that in most "scene changes", as in if the show goes to "all black screen" or you come "in or our" of a commercial... Or even moving from one commercial segment to another, Mythfrontend just crashes. Not all recordings behave this way, but I would say that all recording from some channgels DO behave this way. (THey are all recorded from the same STB to composite on the PVR).

Below is a log dump of me starting to watch a recording, until it crashes. SOmetimes (very rarely) I also see

"pure virtual method called terminate called without an active exception "

Anything I can / need to do to help with more info. Let me know.

dupe of #9166 ?

Ok, I just noticed something.

The channel that does NOT cause this broadcasts all their content in 16:9. THe channel(s) that DOES cause this changes between 16:9 and 4:3.

Please attach a backtrace at the point of the crash, as described at http://www.mythtv.org/wiki/Debugging . Thanks.

Since I have no idea how such a file _should_ look, I hope i rebuilt MyhtTV correctly.

ONe slight change. When running via gdb, mythtv doesn't crash to desktop, but just "locks up" when the problem occurs, but maybe that is as expected?

And my comment in "Comment 2" just went out through the window. I just got the same behaviour on the "16:9 only" channel.
