Motion differences


Hi, sorry if this is a silly question.

Is it possible to get motion to only store difference files whist motion is being detected? in other words, motion is detected; that image is stored; then for all files that get created after that only the differences are stored?

Thanks in advance

I believe the configuration parameter for this is to specify pictures or movies as "debug". This will then save the difference files.

Thanks MrDave, but I do not see any information about that config parameter?? frown, sad smile Can you be a bit more specific?

It may depend on the version that you using. This initial message indicates version 3.2.12. If you run motion -h it will show the version to confirm. In 3.2 I believe it was called output_motion. This was then renamed in the later versions to output_debug_pictures. Sorry for the confusion, it has been quite a while since I've worked with the 3.2 config names. I "think" this is what you are looking for with the storing of differences described.

Thanks MrDave, output_debug_pictures on works a treat. Now, can I have motion simply store the first full image and then ONLY the difference images for a motion detection?

Thanks again
