mythfrontend.real crashed with SIGSEGV

[Sven Sprengel]

Binary package hint: mythtv

Was not shutting down properly, so I had to kill the app.

The crash seems to be related to the fglrx drivers.
I tried using mythfrontend (remote) using the ati driver and everythings working fine. Then switched back to fglrx and mythfrontend will not shut down properly.

I think this will be another bug, but with fglrx the sound of of tv is shoppy and video is not playing on after a few seconds. Here also no problem with ati driver.

This is the output what happens now, when I try to watch tv via my notebook, which is the remote frontend, fglrx driver enabled.
On my backend/frontend combo with mythbuntu 7.10 and the latest weekly builds and nvidia card everything is running fine.

Frontend is still crashing, when I try to shut it down properly. You need the dump of it, tell me.

[Bryce Harrington (bryce)]

Can you try either of the following options and see if it resolves it? If so, then perhaps this is just a dupe of 197639.

Option "VideoOverlay" "on"

Option "TexturedVideo" "on"

[Sven Sprengel (svenauskr)]

This really fixed the problem.

Thank you very much Bryce.

Greetings

Sven: Is the crashing on quit fixed? Or just the choppy playback?

I've been victims of both. Adding the suggested bits to xorg.conf certainly cures the choppy playback, but I still get a crash upon exiting the recordings menu after watching a recording.

I notice bug #206156 is from Sven as well... if that's the crash mentioned in this ticket, can we change the summary/description for this one to deal only with the choppy playback?

[Sven Sprengel (svenauskr)]

Choppy playback is gone. Works fine now for me.

Yesterday, the app didn't shut down porperly again, so I had to kill it again. But today it shut down well, but I guess this is due to the update of the kernel and the fglrx-modules from today.

You can change the the topic name as you like, because I don't know how to do it.
