Re: PiKrellCam: motion vector detect + OSD web interface

I am seeing the occasional h264 file in the videos file and when I do a conversion using ffmpeg I see this warning Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly Is this a problem waiting to happen ...

Re: PiKrellCam: motion vector detect + OSD web interface

Just updated to V5 of PiKrellCam (using the Upgrade button in the web interface), and now the camera view will not show up. It's stuck on "Waiting for first image". VNC/SSH-ing into the Pi works fine. BTW this is on a RPI 3a+, but that really shouldn't matter. I have 3 other cameras running 4.3.2 j...

Hello, Hopefully somebody can tell me why the h264 file is being deleted. I'm still getting thumbnails but no videos.

Any idea why I can't delete files through the web page?
The www-data user needs write permission for the web page to able to delete, so recheck that.

From the command line, a quick test that www-data can delete is:

Code: Select all

sudo -u www-data bash -c "rm /path_to_samba_file"
Does that work?

The HQ camera photos look like a great improvement. If only I had tried to get an order in before they sold out. But I'll eventually get an HQ camera and have a pikrellcam update then. In the meantime, if you care to try it, bypass the GUI and edit pikrellcam.conf by hand after quitting pikrellcam. ...

Re: Outdoor Security Sensors

I have several PIR sensors around my house that signal back to a Pi wireless. They are 433MHz PIR modules that are read by a SDR dongle on the Pi. I bought these a while back and at least at the time they transmitted their codes on 433 MHz: https://www.harborfreight.com/search?q=driveway%20alert%20s...

Is there any way to "artificially" trigger a motion event after a motion video has reached its time limit?

@billw, Just for entertainment, I'm fooling around with the html.

It looks like command_process() is unable to get to the "config[]" entry because...

Re: PiKrellCam: motion vector detect + OSD web interface

@billw - Is pikrellcam using mostly GPU or CPU for the motiondetection and video conversion? Perhaps I am setting the memory split to high (256mb on Pi0) I remember a block diagram of the program that I saw but I cannot find it anymore, though I think a lot of processing went on in the GPU? I am al...

Re: Combining PIR and normal motion detection?

You could run pikrellcam without enabling motion detect videos because it always writes motion detects to a FIFO regardless if it is enabled to record videos. There is an example script example-motion-detects-fifo that reads this motion detect fifo to get all motion detects and you could combine you...

Does having the "check_*_diskfree" lines in that order in the .conf file, mean that it first checks the current day's media and deletes that, before even checking the much larger archive/* media folders?
