Segmentation fault: when starting livetv with ExternalStreamHandler using jpoet Colossus2 support

[ibedonc]

was asked by jpoet to open this

my dump is to big so here is a link to my cloud server ​https://www.roosterclaw.net/owncloud/index.php/s/yyDXrduT3l3to7l

recordings work , just not livetv also using hdhrrecorder blackbox works with livetv

[jpoet]

ibedonc, is that attachment a back trace? A back trace should not be near that big -- it is just a text file.

[jpoet]

Hi ibedonc. Thank you for creating the ticket. Please attach a backtrace. You can find instructions here:

Thanks.

sorry first time I have ever done this , creating the back trace now

[ibedonc]

that link is a zip (179M) file of /var/crash/_usr_bin_mythbackend.110.crash that is not what you need ?

Hi ibedonc. I am available again, and can work on this.

The file you have linked to seems to have a core dump embedded in it. There is not much I can do with that since my system is not identical to yours. A back trace is a textual representation of what all the threads in the program where doing when it crashed. That combined with a log file should allow me to figure out what when wrong.

I did try and reproduce the crash on my own system, but LiveTV with the hauppauge2 external recorder worked okay -- within the limits of LiveTV and MythTV. In other words, I did get some "Could no open decoder" errors, but when it got past that, everything worked as expected.

ubuntu puts crash files in /var/crash , that is where that came from

I was out of town for a week , I have a new system that I have not had the time to put in place , I plan on putting .30 on it and I will test it with that

Original reporter has not commented in 11 months, so assuming this is now working for them.
