That is not happening with previous snapshot ( motion-3.1.18_snap7 ) so maybe is related to last patches i guess that ffmpeg ones.

Environment

Motion version: 3.1.18_snap8
Shared libraries: curl, xmlrpc, ffmpeg, mysql, postgresql
Server OS: debian Sarge, kernel 2.6.8

Follow up

Fix record

It happens if you compiled ffmpeg with the option --disable-risky , so avoid to run configure with this option if you compile ffmpeg from source.
