segfault when starting playback / watching tv

Hi

this is on the frontend. I have recompiled with debug enabled here's the
output. I'm on kubuntu hardy. Remote frontend, connecting over wireless.
I'm on a Mobile P3.

Program received signal SIGSEGV, Segmentation fault.

This looks like the ld-linux/libGL segfault that was pretty common with
the Ubuntu builds for a while after 0.21 came out. I haven't heard much
about them, lately, so I'm guessing the Ubuntu packaging wizards got it
figured out. You may want to check in #ubuntu-mythtv on freenode to see
what they did/what they know. Chances are you just need to build it
differently.

Re: segfault when starting playback / watching tv [In reply to]

Forgot to mention the version number - it's
mythtv-frontend_0.21.0+fixes16838-0ubuntu3_i386:
MythTV Version : 16838
MythTV Branch : branches/release-0-21-fixes
Library API : 0.21.20080304-1
Network Protocol : 40
Options compiled in:
linux debug using_oss using_alsa using_arts using_jack using_backend
using_dbox2 using_dvb using_firewire using_frontend using_hdhomerun
using_iptv using_ivtv using_joystick_menu using_libfftw3 using_lirc
using_opengl_vsync using_opengl_video using_v4l using_x11 using_xrandr
using_xv using_xvmc using_xvmcw using_xvmc_vld using_glx_proc_addr_arb
using_bindings_perl using_bindings_python using_opengl
using_ffmpeg_threads using_libavc_5_3 using_live

Please note - and I'm already kicking myself - that it could be unrelated
to mythtv as it doesn't happen using a different (fresh) user account
under a second x session.

thanks

Re: segfault when starting playback / watching tv [In reply to]

Hi and thanks for pointing me into the right direction. I downloaded the
source package and modified the build settings like this:

63c63,64
< CONFIGURE_OPTS
+= --cpu=i686 --enable-mmx --enable-xvmc --enable-xvmc-vld --enable-xvmc-pro --enable-glx-procaddrarb
---
> CONFIGURE_OPTS
+= --cpu=i686 --enable-mmx --enable-xvmc --enable-xvmc-vld --enable-xvmc-pro
> # --enable-glx-procaddrarb
91c92
< --enable-opengl-vsync --with-bindings=perl --enable-opengl-video \
---
> --with-bindings=perl \

Rebuild the package, installed it and now watching or playback dont crash
anymore.

It might be linked to having an ATI Radeon card and some OpenGL issues though
I don't even have OpenGL in use anywhere.

Hope this helps someone in the future.

Regards,

mimo
