PVR-350 LiveTV: not responding to input
| Reported by: | Owned by: | danielk | |

Description
Using svn versions from 8527 until 8605.
System details:
Pentium 4, 256 Mb RAM
combined front/backend
pvr-350 ivtv 0.4.1
FC3 kernel 2.6.11
qt-3.3.5-11
kde-3.5.0
After viewing LiveTV on a single channel for varying amounts of time, the frontend fails to respond to remote, keyboard, or mouse. LiveTV continues playing fine on that single channel indefinitely. The only possible recovery method is a cold reboot. There isn't anything obvious that stands out in the myth debug logs or syslog, but I have attached the myth backend and frontend logs using -v all,noaudio,nodatabase.

gdb trace of frontend hang on exit from LiveTV
comment:3 Changed 14 years ago by
I have attached a gdb trace, hopefully in the correct format, of the frontend going black on exit from LiveTV. This isn't the exact problem described in this ticket but I included it here are part of the troubleshooting of this issue. Let me know if I should open this as a new issue.

gdb trace when frontend does not respond to input
comment:4 Changed 14 years ago by
I've added a gdb trace for when the frontend stops responding to input. No error was thrown in gdb and as far as I can tell, nothing interesting is included in the trace. I've only debugged the frontend, I'll try the backend over the coming weekend.

You need to compile MythTV with debugging symbols to make useful backtraces. See: TicketHowTo and http://www.mythtv.org/docs/mythtv-HOWTO-22.html#ss22.2
Preliminary results indicate that this doesn't happen when using xv, just when using the 350's decoder. I've only let LiveTV go on xv for half a day, so it is still alittle early to say for sure.
