All YLE (FBC) recordings crash on 0.24

[jrauti@…]

Every recording from Finnish Broadcasting Company (YLE) crashes mythfrontend immediately after playback starts. I have recordings going back couple of years and every single one crashes. All other channels work without any problems. If I watch channels live there is no crash. This started in late 0.23-fixes but I was bit too busy to file a bug. This might be related to closed ticket #9007. Output from mythfrontend --version:

Is this DVB-C or DVB-T ? I'm using myth 24 succesfully on Welho DVB-C network. I have no experience on DVB-T though, which is national wide terrestial broadcast. Just saying this problem doesn't exist in local cable with YLE Teema or YLE TV2, by doing quick test. I'm now running mythtv 24 fixes -r27210. I'm running it on ubuntu lucid.

Did you do 'make distclean' before compiling, and cleaned compiler cache by doing 'ccache -C' ?

[Kenni Lund [kenni a kelu dot dk]]

Please read the TicketHowTo. It would have told you not to set the milestone, not to change the priority and to include a backtrace whenever you have a segfault.

Please provide at least a backtrace (http://www.mythtv.org/docs/mythtv-HOWTO-22.html#ss22.2 or http://www.mythtv.org/wiki/Debugging) and if possible, a small sample.

[jrauti@…]

Here is whole backtrace. Sorry it took while but learning how to do debug version on program in ubuntu took while. This is also slightly newer version than in first report: Please attach all output as a file in bug reports. Example file can be downloaded from ​http://www.kati.fi/jrauti/test.mpg (10 MB)

This appears to be a bug in libmpeg2. Why are you using libmpeg2 as the decoder instead of ffmpeg? What happens when you do?

[anonymous]

Thanks. Switching to ffmpeg fixed this. I have Nvidia 7200GS in my machine and I tried to activate xvmc in summer but results with OSD were visually degraded (this was 0.23-fixes). Somehow when I switched profile back I chose libmpeg2 instead of ffmpeg in my profile. Can't tell difference in CPU consumption in 1.73 GHz Pentium-M both work in 800 MHz mode consuming around 20% of CPU. Everything else worked so I never connected that test to this problem. Sorry for bother. This ticket can be closed.
