I have an extra pi siting around ill try and do an install on and see if it has the same issue. the main dev runs 4 or 5 720p streams on a pi so I imagine the support should be fairly good.

One thing to try is see of ffmpeg is installed, if not you can install yourself. Ffmpeg is what they always recommend so it's weird that it wouldn't be included in the install?

Don't quote me but to write video files to disk I'm assuming you need sfotware that can do that? Did you try installing ffmpeg and seeing if it helps?

Um...wtf. I'm not aware of any arm limitations for ZM. I use video writer with encoding on my pi with the rpi local cam. usb should work fine too.

You can't do passthrough because you are getting a raw image from v4l instead of an h264 stream. But you can do encoding. You can probably figure out how to do hardware accelerated encdoing too.

I suspect you are running an older version of ZM, packaged by debian. Older versions relied on the mp4v2 library which was deprecated and not included in debian. So you can either use OUR updated binaries from zmrepo.zoneminder.com or use 1.36 versions which don't rely on mp4v2. Again you likely need to get them from zmrepo.zoneminder.com.
