Ah, not what I was expecting! ext4 is a proper file system. Good. Direct SATA connection -- Good -- this rules out flaky USB enclosures and CIFS/SMB networking devices that don't know how to work properly. The wide permissions being deliberate I can understand, please make sure to re-attach the door...

Need more information about the external drive -- most importantly, is it using a FAT filesystem, or a proper one like ext4? How is it connected (USB, network?) Model number etc. (so others can Google what you've got). It is possible that the drive is using a FAT file system (which is pretty clueles...

You may want to search the forum for posts regarding keywords: FFMPEG and "streaking, smearing, blurring" ... to see if you can optimise how you are handling the video streams.

Reducing resolution and frame rate can relieve some of the stress on the system, making it appear stable

My guess is you changed the thing that needed to be fixed, but it didn't get picked up by Zoneminder/MySQL/Apache which was already running and happy being 4 hours adrift.

Until something caused one of [ZM/MySQL/Apache] to re-read its config, restart, reboot, at which point it "fixed itself"

Well that's even worse, because that collection of horizontal resolutions are ALL indigestible by 16

As in -- I would hope they all make something feel unwell!

Why would divisibility by 16 matter in one dimension but not another? As per iconnor's post -- I just discovered that when batch transcoding videos at their "supplied size" into xvid/mp4 formats, I would get a hard "segmentation fault" refusal from FFMPEG for some of them. The only thing in common ...

It may be that 1920 divides exactly by 16, yet 1080 does NOT divide by 16.

I've come across general video-handling-with-FFMPEG problems when using X-resolutions that are not exact multiples of 16, so have become sensitive to that one

Can you check and edit this post, as it looks like part of the printf got munched away (here AND in your other posting of it) -- there's an unbalanced quote which made me notice ...

"E.AlarmFrames < -2 weeks " This makes no sense to me, it might to you :) If AlarmFrames is a count of how many frames are "alarmworthy", then what is the meaning of "< -2 weeks"? It would be odd to have less than -2 alarmed frames, wouldn't "0" be a real-world minimum there? I think maybe something...

Where is zm_ffmpeg.cpp located in a standard zoneminder install? I was gonna investigate line 70 of that file to see what's up with it. For future general Unix reference ... if you have locate or slocate installed, you can do this :- # locate "zm_ffmpeg.cpp" /usr/local/src/zoneminder/ZoneMinder-1.2...

Although the USB spec does allow a tolerance under/over 5v, and other devices may well work with that PSU, a lot of the "Raspberry Pi approved" power supplies are set for the upper end of the voltage range to help with this.

Definitely sort out your power supply -- if you are getting under-voltage reports, and the CPU is throttling, you have an overloaded, defective or poor quality power supply. ZM crashing is a likely consequence, so is the whole system hanging, data corruption, and destruction of the contents of the m...

'-filter:v crop=1000:740:640:480' perfectly Could anyone give me a hint how can i crop the source video stream (before processing by zm)? Two things :- Your command line seems to cut a 1000x740 box out of the source video, positioned 640 along and 480 down. Is that really what you meant? It's an un...

... but the way I see it, these modes just replaces the start/stop states anyways. Then there would be no point having "states" if they are just other ways of saying start and stop. The normal "start -> running" state and "stop -> stopped" state are in addition to any you define, not instead of, or...

great feature if all or selected cameras could be turned on/off based on time of day. Only way I found so far is to set up a cron task that in effect stop or start zm based on my cron schedule. There is a way to do this, you've nearly got it already. Instead of accepting the default "run states" of...
