I installed with this guide and updated my zoneminder.conf file to reflect this post.
Most things are working now but I'm having an issue recording from my remote monitor with my Video Writer set to X264 Encode. It looks like JPEG capture is somewhat working. I can see some images in events but also see NO DATA in the montage tab.
I do notice the following error in the logs when motion recording should be triggered:
ZoneMinder was not compiled with the X264 MP4 video writer, check dependencies (x264 and mp4v2)
I quick checked what packages are installed via "dpkg-l |grep 264" and see that I have:
ii libx264-155:amd64 2:0.155.2917+git0a84d98-2 amd64 x264 video coding library
This is very new to me so lmk if I'm leaving out any details. My installed version of Debian:
Linux ZoneMinder 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5+deb10u2 (2019-08-08) x86_64 GNU/Linux
