No recording, Mode Record, Analysis/Decoding disabled

Post by trumee » Sat Jan 23, 2021 8:45 am

Hello,

I want to record 24x7 a 1080p camera with Decoding disabled to save CPU. I have disabled Analysis and Decoding in the camera settings. Unfortunately, the camera does not record at all. There is no event appearing in the webui. The log file seem to indicate that it is recording, however there are recording in the events folder.


Code: Select all

If i change the camera to Modect then it works correctly. So i am guessing there is some issue in Record mode.

Read the description.
MoDect is what to use, if I got what you want.

With 1.34.x I used to use zmrecord script as described here.

@iconnor mentioned that the script is no longer required in 1.35.x. Thus i setup a camera in 'Record' mode and disabled decoding. I dont want to use Modect on this high resolution camera, and only want to record a stream 24x7 without analysis/decoding (akin to directly storing using ffmpeg).

Nevermind, i had a filter which was deleting the events. Upgrading from 1.34.x to 1.35.x messed up my filter logic.

Also, I enabled 'Analysis' on the cameras. They seem to be behaving now.

One thing, I miss from the 'zmrecord' script is that you could directly download the mp4. In 1.35.x method, i have to first download a zip/tar and then extract it to get to the video.
