Software to Post Process MPEG4 (h264) for motion detection?

I'm sure it can be written, but is any aware of software free to download

that will extract motion detection events from an existing mpeg4 (h264)

video file?

No. The video files are not continuous pictures like JPEG.

You might be able to do this capturing every 5th one, or so as that would give you a "picture" rather then parts of a picture.

You would have to buy SDK for Java, and perhaps other software, and you would need a JAVA decompiler.

The rest is above my paygrade.

If you could convert it to AVI (perhaps using HandBrake) then using VB6 (or other) you could convert it all to images:

There is one utility you can try. Here is the link,

Just grab the SafeMotion utility.

It's a console mode program and works on AVI and MPG files with MJPEG, MPEG4 and H.264 encoded video clips.

Hope it helps!

i've downloaded this tool and played a little, but the tool can't seem to read my backup files, what should i do now?

you need to convert the backup videos to avi or mpg files for the post processing. most dvrs should come with a video converter program.

moreover, it could turn your pc cam into a single channel dvr with motion detection, and its free.

got it working for my backup footage. it works great for my front yard analysis by applying grid mask. now i get to see who, or actually what is visiting my yard messing up the grass.

Thanks jj!
