MythFrontend SEGFAULT'ing on LiveTV

[anonymous]

Ah silly me. I decided to update my box to latest subversion and now I can no longer watch TV or recorded content.

Ubuntu Dappper box, using svn 11636

Make distclean on compile.

Re-compiling with debug to get back trace now.

Oh and my compile time settings...

./configure --enable-xvmc --enable-opengl-vsync --enable-dvb --disable-ivtv - -enable-proc-opt --disable-dbox2 --disable-hdhomerun --xvmc-lib=viaXvMC --disabl e-freebox --disable-firewire

Backtrace of segfault

[michael@…]

So using xvmc, it seems that this line might be of interest, (complete lack of mythtv programming knowledge revealed here):

tmppicture = {data = {0xa090a10 "avlib should not use this private data in XvMC-VLD mode."

Or is this normal ?

[michael@…]

After updating my libviaxvmc libs and -devs on ubuntu and recompiling, these seems to have disappeared. Unless anyone else is having issues, then I seem to have fixed this myself, not related to mythtv.

Appears to have been an external library problem.
