the instructions say that it is better to use 'ffmpeg' than 'remote' as the source type. Can someone explain the difference here?

I have 4 Reolink that work fine with 'remnote', but with 'ffmpeg' have the known lubricate effect.

Remote uses its own code for Connecting to camera, aka RTSP etc, then hands frames to ffmpeg to decode. Ffmpeg uses ffmpeg libs to do that.
Probably points to transport side being your problem, maybe a translation error here as known lubricate problem doesn’t seem correct. Do you mean picture turns to vertical lines or smears? Like it got some of the picture and then melted? That is ffmpeg missing frames, have you tried TCP?

i use an i5@3.2Ghz with Zoneminder in the dlandon-Docker and actually 7 Cams for testing and learning. But if i use modect for more than 2 Cams, htop shows me 100% on every cpu. i think, this is way to much cpu-usage, even for this "old" cpu.

i think (as a newbie) that the cams are not properly set up and the conversion of the events to jpeg might be the problem. so i found the setting "Video Writer" at Storage, but H264 Passthrough seems only possible if i use ffmpeg. so i changed my cam-setting from remote to ffmpeg and recieve smearings.
i dont know, where to start looking for the problem.
i will post some pics with settings from 2 cams.

2 more pics...

... and the last 3 from the cam with remote-settings

the best pictures without loss at montage review do i have with the remote-setting.
And the Cams are reolink 410 5mp...

This being a reolink, you might want to check viewtopic.php?f=10&t=25874&hilit=reolink

I don't use these cameras myself, though.
