[Motion-user] Segmentation fault following re-compile w/ FFmpeg

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello,

I'm getting a segmentation fault after re-compiling motion (Mr. Dave's fork
at 9b4c16c, revise version number to 3.4.1) to use FFmpeg.

Some particulars:

   - I'm running on a Raspberry Pi Model B, PCB revision 2.0 with Raspbian
   Jessie.
   - I downloaded the FFmpeg source and compiled it overnight. Many
   warnings, but no errors. It runs when passed --version, but I've not done
   anything with it standalone beyond that.
   - I had previously compiled motion with libav (and it worked, though
   some things were missing, which is why I wanted to try FFmpeg).
   - In preparation for the re-compile with FFmpeg, I saved my old binary
   and ran make clean.
   - Configure --with-ffmpeg=$HOME/ffmpeg seemed to indicate it found what
   it needed, since I think it output "FFmpeg yes," or something similar.
   - I've pasted in the log below. Even at level 9, there's not much there
   prior to the crash.
   - The second line in the log makes me wonder if libav has snuck in: [0]
   [NTC] [ENC] [May 07 11:12:17] ffmpeg_init: ffmpeg LIBAVCODEC_BUILD 3745636
   LIBAVFORMAT_BUILD 3744868
   - I did not get the "YUV420P" warning with the version compiled with
   libav.

I did not remove the various libav packages before the re-compile is that
necessary?

Thanks,
Alex
