Follow up

Please try latest svn -r438 , pay attention that motion.conf has changed,

after generate motion-dist.conf copy to motion.conf and edit , don't change v4l2_palette

that is only needed if you want to choose priority of palettes however autodetection

should work better most of times. So try to setup in your motion.conf :

setup_mode off
v4l2_palette 11 
width 320
height 240
ffmpeg_output_movies off
target_dir /tmp/cam1

Answer

No feedback from user . Probably issue was fixed in svn trunk.
