Hang in Live TV channel change
|Reported by:||skd5aner <skd5aner@…>||Owned by:||danielk|
|Component:||MythTV - Video Playback||Version:||0.24-fixes|
|Severity:||medium||Keywords:||Live TV, channel changing, hang|
mythfrontend will sometimes hang while attempting a channel change within live tv. While I'm not exactly sure how to replicate this on demand, it is something that occurs frequently enough that anytime I have guests over who use Live TV, I inevitably have to restart the frontend due to this issue.
Simply, while watching live tv, when attempting to switch to another channel, the screen will turn black (if changing from the guide, you'll see the theme background image for several seconds before turning black), and become unresponsive to any input via lirc, keyboard, or otherwise. No dialog boxes or OSD information is displayed. The OS will respond to keyboard commands such as alt-tab in which I can bring focus to a console and kill the frontend that way. This occurs "randomly", at least from what I can tell as successful channel changes occur about ~85-90% of the time.
I've attached a backtrace (compiled source in "profile"), a mythfrontend -v playback,channel, and a master mythbackend -v file,channel,record. I also have a slave mythbackend log as well, but I do not think it's necessary to attach yet since none of the tuners attached to it were used while attempting to watch Live TV. If asked, I can attach it upon request.
If there are any additional details needed, please let me know and I'll do my best to provide/test whatever I can.
Thank you in advance!
