Comment (by WilliamDeRieux@…):

 Replying to [comment:5 michael@…]:
 > I have this same problem with recordings performed on a composite
 device.  LiveTV works normally, with exception of when changing channels,
 sometimes get an errors like #12903 - But that happened in 0.27 as well.
 >
 > When running normally, backend segfaults soon after a recording is
 started.
 > When running mythbackend under gdb, backend does not segfault, but get
 streams of messages:
 >
 > mpeg4 @ 0x7fff20007800 AVFrame.width or height is not set
 > mpeg4 @ 0x7fff20007800 AVFrame.format is not set
 >
 > Recording completes and file is watchable.


 ----
 '''The fact that you are getting a segmentation fault in
 TryWriteProgStartMark -- even though you experience the same
 bug at I have....the segfault is actually something new.
 I have never had a segfault occur in RecorderBase::SavePositionMap /
 TryWriteProgStartMark.'''

 What distribution are you running?

 I see your version of mythbackend is: fixes/0.28 [v0.28-97-ge9d0543]
 and that it was compiled against: Qt 5.2.1

 -- Did you compile this your self or are you using a version from your
 distribution?

 The version that i use was from commit
 7f8f1688e882cd0587097fe4867e20d8fa122cce (Oct 22, 2016) (Frontend and
 backend changes to support music choice.)
 https://github.com/MythTV/mythtv/commit/7f8f1688e882cd0587097fe4867e20d8fa122cce
 I also compiled it against Qt 5.6.1

 you could use this command to test that revision and see if you still get
 the segfault.
