Description

I'm using mythtv svn 22834. When I start Live-TV, it start playing fine (1001 - channel 1). If I change the channel to (1002 - channel 2) the backend crashed. Even if I change to another channel, it always crash.

I've attached a log with -v record,channel,siparser options.

dmesg shows: mythbackend[12283]: segfault at 190 ip 00007f9447f30e3a sp 00007f9431ff9e20 error 4 in libmyth-0.22.so.0.22.0[7f9447d31000+444000]

Can you please get and attach a backtrace with debug symbols, as described in the TicketHowTo and at http://www.mythtv.org/wiki/Debugging ?

I've attached a debug file. I hope i've did it the right way.

I have the same problem. I have found a workaround. I only have segfault when switching to channels on the same mux. If I switch to another mux and back again there is no issue.

comment:5 by FreddyX, 17 years ago

Yeah, when switching to another mux, channel changing works. On the same mux, backend crash. Very strange. My wife saw it first on last friday-evening. My system build it every morning from svn. But it could be earlier because we don't watch live-tv every day.

The same happend with recordings. The first recording starts fine but the second on the same mux starts but there is no file. If second recording start on another mux it is also fine. Please let me now if you want more information.
