this could occur for non-lossless transcodes, but that is all I have set
up and care to use for my personal needs atm.

When running a Transcode job from within MythTV the job will segfault.
Upon attempting from the commandline using the command shown in the
backendlog I get said segfault as well. I've run a backtrace, I will
attach apport crash report(s if multiple are needed?) when I get home and
can easily upload the file.

Comment (by adeffs.mythtv@…):

from apport, as per the wiki

https://bugs.launchpad.net/mythbuntu/+bug/962353

if that doesn't work for the devs I can create an "old school" gdb grab.

I've attempted a gdb run of a transcode job, don't know if it will have
any better information though?

Comment (by beirdo):

Umm, when using gdb, we actually need a backtrace.

{{{
thread apply all bt full
}}}

Also, this is dying with qFatal. That means that Qt sent a fatal error
message to the console where this was started, and that message is
critical to figuring out what it didn't like. If you ran this from the
prompt, what were the last few lines after the console logging?

Comment (by Steven Adeff <adeffs.mythtv@…>):

This seems to have been fixed, though only for the master backend, at
least in my system. I still have a few recordings that error, but not for
this reason. I'll open another ticket for that issue.
