[mythtv-users] One particular recording segfaults - trunk

[Stephen Robertson]

Hi all,

I've got a recording that was made last night that the frontend refuses to
play.  I have also tried running it through mythcommflag which gives the
same results.  The file plays happily with VLC 0.9.9.a

The last thing that mythfrontend and mythcommflag log is [mpegts @
0xb7399800]max_analyze_duration reached.

This log message is coming from mythtv/libs/libavformat/utils.c

The recording that won't play has ten streams whereas the "normal" recording
has one with four "sub-streams" (Not sure of the terminaology)

Unfortunately this build wasn't built with debugging symbols but I can try
rebuilding my own build if that will help.

Any clues or anything I can do to track down the problem.
Stephen
