setting up zm on raspberry pi
|
|
|
|
installed raspbian,
|
|
|
|
installed zm per docker steps
|
|
|
|
using entrypoint.sh in docker utils
|
|
zm wouldn't start, because zmsystemctl is not working via this docker script
|
|
|
|
i migrated to devuan
|
|
(change apt repos, then apt-get install sysvinit-core, then reboot)
|
|
|
|
and it now doesn't try to run zmsystemctl and it actually works
|
|
|
|
|
|
next error:
|
|
failed to open vchiq instance
|
|
|
|
this reportedly has to do with www-user not having permissions to video group
|
|
let's change that...
|
|
usermod -a -G video www-data
|
|
usermod -a -G wheel www-data
|
|
|
|
edit: that was not it. dead end.
|
|
let's try
|
|
https://raspberrypi.stackexchange.com/questions/19436/how-can-i-permanently-fix-dev-vchiq-permission-errors
|
|
|
|
chmod 777 on /dev/vchiq worked.
|
|
NOTE: it looks like a reboot would've worked for the video group as well.
|
|
need to log out and back in the www-data user...
|
|
|
|
but i 777'd it.
|
|
|
|
|
|
|
|
Now, on to testing the RTSP path for H264, and use passthrough.
|
|
|
|
I tested the path in Mplayer and it does work from my laptop, so the path
|
|
is correct. ZM doesn't seem to work. Something with ZM is broken...
|
|
|
|
i tried to run the onvif probe...
|
|
seems there are a couple dependencies not installed on
|
|
this install for onvif probe
|
|
i'm giving up for now on configuring onvif probe.
|
|
This is no doubt due to it being a docker script.
|
|
|
|
|
|
rtsp://admin:@192.168.1.138:88/videoMain
|
|
this path works in mplayer but not in zm ffmpeg.
|
|
let's try changing to tcp or udp or something else...
|
|
OK
|
|
this time it seems to work sorta
|
|
except

I rebooted the camera, tried mplayer again and it worked.
|
|
|
|
I set the zm rpi to videoSub and resolution 640x360
|
|
and it didn't work, but then two minutes later it worked... hm..
|
|
|
|
Load is good. I've taken a picture. very low. Looking at 3%
|
|
wow.
|
|
|
|
OK, but that's 640 x 360. Let's try HD, and then let's try both without
|
|
mmal to see if there's a difference. See if the mmal is implemented in
|
|
this zm.
|
|
|
|
tcp by the way, on ffmpeg.
|
|
tcp, ffmpeg, the path above, and videoSub worked.
|
|
trying videoMain now, let's see if it suddenly catches after a few minutes.
|
|
|
|
I didn't have any luck with HD.
|
|
I tried rebooting camera, no luck.
|
|
|
|
I set it back to 640 x 480 and it caught near immediately (within a minute)
|
|
this seems to be what the rpi wants. It looks like HD isn't working with the RPI.
|
|
|
|
Load is low. I'm going to take this device on the road, and try it with
|
|
a couple more cameras. Let's see how many SD cameras we can get running
|
|
on it.
|
|
|
|
Load is about .7, though htop shows no more than 5% on any given core (more
|
|
around 1-3.3%.
|
|
|
|
So for rpi3, I'd stick with SD for now.
|
|
|
|
TODO: try more cameras, try ffmpeg without mmal...
|
|
|
|
just as a reminder there is
|
|
armel (32 bit arm without hardware floating point peripheral)
|
|
armhf (32 bit with fp peripheral)
|
|
arm64 (64 bit arm)
|
|
|
|
Although each device has its own requirements beyond that which is why
|
|
arm is shit and not nearly as compatible as x86. I digress.
|
|
|
|
|
|
After looking a bit more, I realized that they aren't using the binary ffmpeg in ZM. I've never really
|
|
investigated much. I have used MJPEG up to this point.
|

|
|
dev@raspberrypi:~/ZoneMinder/src $ less zm_ffmpeg.cpp
|

dev@raspberrypi:~/ZoneMinder/src $ grep -r mmal

Ah, so it is working. but I don't know where the decoders are found....
|
|
|
|
|
|
|
|
However, I'd like to disable it, to see what the difference is.. How do I do that?
|
|
|
|
And even with all this success, the foscam, still has too slow of a h264
|
|
stream. My cheaper Amovision camera gets better FPS than this... 3.5 vs 15fps.
|
|
|
|
At least CPU is low.
|
|
|
|
|
|
here's an idea. Let's change it to remote, which doesn't use mmal
|
|
and see what the resource usage is.
|
|
not exactly the same, but similar.
|
|
|
|
hm.. getting a no rtsp sources error. Will give up on that for now.
|
|
|
|
|
|
looking at the code
|
|
and this forum post:
|
|
https://forums.zoneminder.com/viewtopic.php?f=34&t=26112&p=100221&hilit=avcodec_find_decoder_by_name#p100221
|
|
ffmpeg libavcodec
|
|
includes mmal codecs. Let's see if I can get an older one without libavcodec.
|
|
|
|
https://packages.debian.org/stretch/libavcodec-dev
|
|
this is the package we want to get an older copy of .
|
|
|
|
Hm.. well as long as I know mmal is being used, I don't really need
|
|
to test the old one, but I would like to.
|
|
|
|
Question is, how to get the old version, without mmal installed...
|
|
|
|
http://snapshot.debian.org/binary/libavcodec-dev/
|
|
has it
|
|
but when was mmal added, and it is compatible with stretch...
|
|
Maybe I should just install 1.30.4 and compare that... Might be easier
|
|
in this case.
|
|
|
|
That is the end for now.
