#11859 closed Bug Report - Crash (Fixed)

mythcommflag seg faults in ff_put_pixels16_sse2.loop

Reported by: Jack Perveiler <perveilerj@…> Owned by: Jim Stichnoth
Priority: major Milestone: 0.27.2
Component: MythTV - Mythcommflag Version: 0.27-fixes
Severity: medium Keywords:
Cc: Ticket locked: no

Description

Backtrace attached.

My executables come from mythbuntu 0.27 repositories, version file attached.

To reproduce (if you had my .mpg file): mythcommflag -f (my_file.mpg).

Let me know if you need the file, I'm not sure that chopping a piece of it will be sufficient to reproduce the bug.

This should already be fixed in the latest Ubuntu packages. The version you are running is a few days old now.

I would be grateful if you could update and confirm?

I updated just before getting the backtrace and update manager says I am still up to date. Maybe my repos are wrong? Here they are:

deb http://ppa.launchpad.net/mythbuntu/0.27/ubuntu precise main deb-src http://ppa.launchpad.net/mythbuntu/0.27/ubuntu precise main

Apologies, I was looking at the wrong branch when comparing the version information. That version isn't as old as I thought.

The first 3 MB of Jack's sample - https://docs.google.com/file/d/0BxETmfuHvGPQdUxLdFVVd3J2YWs/edit?usp=sharing - show a (different) crash under mythcommflag. Import into Video Gallery, then run

mythcommflag --skipdb --method logo --file 2743_20130916110000_short.mpg

The complete file and the short version both segfault immediately at the start of logo detection. This seems like an upstream ffmpeg bug, but I could be wrong.
