In the source tab of a camera source there's a field for options to pass to ffmpeg. However the examples aren't command-line flags, and if I enter a CLI flag there I get either a parking error or an error that ffmpeg doesn't recognize the option. So, what options are intended to be passed via that ...

i3-4130T is just a dual core Haswell @ 2.9ghz. High CPU utilization would be expected for an 8MP 32bit h264 stream @ 30fps. If your goal is to stick with the CPU but achieve a lower load, then I don't see how you could avoid dropping the frame rate and perhaps the resolution too. I replaced it with ...

What is the purpose of decoding the video stream regardless of settings? If it's set to pass-through only, this serves no purpose.

I looked at this thread and disabled the Spectre V2 and page table isolation mitigations (confirmed the grub settings took effect at next boot via dmesg). It actually increased my CPU utilization. A single monitor, no recording, set to h264 passthrough is now taking 80-90% CPU.

I set up a monitor with h264 passthrough for an 8MP camera. CPU usage on an i3-4130T is around 70% of one core: 6937 www-data 20 0 1183804 735668 672544 R 70.4 9.1 0:50.17 zmc Should it be this high when no users are actually looking at the video stream?

That's not quite what I'm looking for, because I want the video files to stay with the events, and get cleaned up by Zoneminder when it's time to expire them, or the disk gets full. All I want is for each event to create an MPEG or AVI and drop the JPEGs after Zoneminder has moved on to recording in ...

I have Zoneminder currently running in continuous record mode. It creates a new event every 10 minutes. For every 10-minute event, I'd like to convert the JPEGs (from the MJPEG stream off my cameras) to a video file, and remove the individual JPEG image files (this should reduce my disk usage by ...

Ok. Now this is probably blasphemy on this forum, but are there any suggestions of free Linux software to save and manage just the MPEG4 streams? For this particular application, a low-power system that just saves compressed video to disk will be fine, I don't plan on using any motion detection or ...

The MJPEG encoders will work with Zoneminder. The compressed stream(s), audio input, on-board motion detection, video / audio output will not be supported. Great, thanks! Next question, for Zoneminder is it more CPU-efficient to use something that provides MJPEG output (such as the Bluecherry ...

Will Zoneminder work with the Bluecherry MPEG4 or H.264 capture cards? I see that the BC-08240A has MPEG4 and MJPEG encoders onboard, I assume if Zoneminder supports this card it would record the MJPEG stream?

Thanks!

To calculate Hours of Operation, the Nominal Capacity of the Battery (in Milliamps) is divided by the Total Current Consumption Rate of the items being powered by the battery. Example: An 800mA battery (.8Amp) is being used to power a black and white board camera that consumes 150mA per hour ...

Gaah! I turned on debugging...and everything behaved normally. Turned it off, and everything looks normal still. (restarted ZM after changing the debug settings each time). Okay...let's try an experiment...4 of the 5 cameras are in the same room, when we shut off the lights the framerates on those ...

That was one of mine and it turned out if i recall to be an overheating northbridge. New mobo fixed it I'm reluctant to suspect the hardware at this point, this box came out of service as part of a MySQL cluster with no problems, and is identical hardware to a number of other machines we have ...

It doesn't help at all. The image is still delayed whether I refresh the window, or close and re-open the monitoring window. I've tried turning off ZM_NETCAM_REGEXPS and setting HTTP 1.0 and then restarting ZoneMinder...the CPU usage of the other zmc processes drop dramatically, but this particular ...
