Description

Mythbackend segfaulted on me this evening. Some time before the segfault, I had quite a few of these errors in the backend log:

2007-05-13 19:15:24.451 ProcessPAT: Program not found in PAT.

Rescan your transports.

2007-05-13 19:15:24.452 Desired program #8 not found in PAT.

Can Not create single program PAT.

2007-05-13 19:16:53.904 Error: offset>181, pes length & current can not be queried

My system: Fedora Core 2.6.20 x86_64 kernel, AMD Athlon X2 CPU, running the latest 0.20 Myth from ATRpms.net. 1 pcHDTV-3000 and 1 FusionHDTV Lite DVB card, tune to US cable QAM channels.

The backtrace is as follows:

I've had mythbackend crashing a lot with this one

2007-05-13 19:16:53.904 Error: offset>181, pes length & current can not be queried

On 0.20-fixes as well, and it seemed to be to do with corrupt data (I have cheap Twinhan DVB cards which output raw MPEG streams.) I improved up my aerial setup a bit and the errors seem to have gone away for now.

Owner: changed from Isaac Richards to danielk

Please test svn head, we have fixed something like this there.

If the problem persists with SVN head reopen the ticket, but please leave your e-mail, we will need you to help with some debugging.

comment:4 in reply to:  3 Changed 12 years ago by anonymous

Replying to danielk: I'm getting "pes length & current can not be queried" follwed by the subsequent inability to lock to a channel. Restarting mythbackend "fixes" it until the next time it occurs. No segfault though. I get the same behaviour from 0.20 -> latest svn trunk (13705). It is no doubt due to a corrupt stream, I'm having severe tuning issues (is there a known problem with stv0297 QAM64 DVB-C?). I should open a new ticket for that though.

Note: See TracTickets for help on using tickets.
