Unable to install rpos

[jonathan84clark]

Hello,

I am attempting to install rpos on a Raspberry PI3 compute module. The OS on this module was updated to Buster and had a previous install of rpos that was working on Jesse.

Steps to Reproduce

1. sudo apt-get update
2. sudo apt-get upgrade
3. sudo apt install nodejs npm
4. sudo npm install -g n
5. sudo n install 12
6. git clone https://github.com/BreeeZe/rpos.git
7. cd rpos
8. npm install Here is the output I am seeing: npm ERR! Error while executing: npm ERR! /usr/bin/git ls-remote -h -t git://github.com/BreeeZe/node-soap.git npm ERR! npm ERR! fatal: remote error: npm ERR! The unauthenticated git protocol on port 9418 is no longer supported. npm ERR! Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information. npm ERR! npm ERR! exited with error code: 128 npm WARN tar ENOENT: no such file or directory, lstat '/home/pi/rpos/node_modules/.staging/typescript-0a2c1eea/lib/it'

I also verified that this issue occurs on Ubuntu 20.04 LTS npm ERR! Error while executing: npm ERR! /usr/bin/git ls-remote -h -t git://github.com/BreeeZe/node-soap.git npm ERR! npm ERR! fatal: remote error: npm ERR!

Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information. npm ERR! npm ERR! exited with error code: 128

npm ERR! A complete log of this run can be found in: npm ERR! /home/jonathan/.npm/_logs/2022-04-12T21_53_50_440Z-debug.log

Any help on this would be great!

Thanks,

Just checked a few other things. It looks like the BreeeZe node-soap fork is broken. It no longer complies with github' standards as of 1/2022. If you go into the rpos directory and do a npm install soap It will fail. So this is a relatively new issue. I suspect that it can be resolved by modifying either the git or npm settings. It looks like the node-soap repository that BreeeZe was forked from still works and there was a recent commit that appears to have addressed this issue. https://github.com/vpulim/node-soap/commit/94fada0b0b56059c774bc312f662349f8652e6d2 But I'm getting a little out of my depth here.

Looks like the git:// protocol is no longer supported, I changed it to https:// and created a pull request (#136) for @RogerHardiman to look at

HEllo, I too had some issues while installing this newer version. I already have a 3b+ and two zero-s running RPOS. Since a couple of days I-ve been trying to set/up on a zero2. and have it finally sort/of running. I-ll describe my steps to success below>

Some of the steps in STEP 1 I actually did during the entire process but I guess they could just as well be in step 1. Out of the box lite install (A port of debian Bullseye without desktop - autoboot to console)

STEP 1 $ sudo apt-get update $ sudo apt-get upgrade $ sudo nano /etc/apt/sources.list add local mirror: http://raspbian.mirror.garr.it/mirrors/raspbian/raspbian/ $ sudo apt-get install libtool $ sudo apt-get install git $ sudo apt --fix-broken install now libuv1-dev should be installed STEP 2 $ sudo apt install nodejs npm $ sudo npm install -g n $ sudo n install 12 LOGOUT/LOGIN $ node -v v12.22.12 $ npm -v 6.14.16 STEP 3 $ git clone https://github.com/BreeeZe/rpos.git $ CD RPOS $ npm install STEP 4 $ npx gulp STEP 5 $ sudo apt install git gstreamer1.0-plugins-base $ sudo apt install git gstreamer1.0-plugins-bad $ sudo apt install git gstreamer1.0-plugins-good $ sudo apt install git gstreamer1.0-plugins-ugly $ sudo apt install git gstreamer1.0-tools $ sudo apt install git libgstreamer1.0-dev $ sudo apt install git libgstreamer1.0-0-dbg $ sudo apt install git libgstreamer1.0-0 $ sudo apt install git libgstrtspserver-1.0.0 $ sudo apt install git libgstreamer-plugins-base1.0-dev $ sudo apt install git gtk-doc-tools $ sudo apt install git gstreamer1.0-omx-rpi $ sudo apt install git gstreamer1.0-omx some of these give an error... $ sudo apt-get install python3-gi gir1.2-gst-plugins-base-1.0 gir1.2-gst-rtsp-server-1.0 here I had to specify python3 STEP 5.c.1b ~ $cd .. $ git clone https://github.com/thaytan/gst-rpicamsrc.git $ cd gst-rpicamsrc $ sudo apt-get install autoconf $ ./autogen.sh $ make $ sudo make install $ cd .. $ gst-inspect-1.0 rpicamsrc

This is how I could make RPOS work on my zero2. however, I must add that its still not running smooth, my older pi zero-s are both capable of 1080 x 1920 10fps without issues, but on this zero2 which is significantly more powerful even overclocked to 1300Mhz, 1280x720 2fps is already difficult. @BreeeZe @RogerHardiman would you have any idea why this lag?

[RogerHardiman]

I don't own a Pi Zero or a Zero 2 and never tried RPOS on these devices.

I would think the best RTSP stream is probably using mpromonet's RTSP server and not Gstreamer on the Zero / Zero 2

[osvikvi]

thanks a lot, I've never tried mpromonet actually I understood Gstreamer was suggested for use with usbcam. I'm installing it now....

Indeed, the pi reports: "Only Gstreamer RTSP is supported for USB camera video"

[RogerHardiman]

oh, I assumed you were using the Pi's camera. the mpromonet RTSP server needs a H264 v4l2 source, eg the Pi camera and hardware encoding, or one of the USB cameras that encodes to h264 in the camera (most return a YUV image or JPEG image over the USB bus). Although mpromonet may be able to use the JPEG streams now.

Now I know you are on a USB camera I expect the issue is the CPU time taken to receive the USB images and re-encode as H264. It may be worth seeing if you can stream JPEG from the USB camera and get gstreamer to stream the JPEG images over RTSP.

[osvikvi]

Thanks for the suggestion, I'll try to figure it out.

Actually I'm using a 10€ UVC - HDMI->USB in combination with Tandberg / Cisco VISCA PTZ camera's.

[RogerHardiman]

I've got one of those USB HDMI capture devices for 10 bucks. I got one with HDMI passthrough so could intercept the image going to a HDMI monitor. Nice idea to use RPOS to turn your camera into an ONVIF device and/or RTSP device. I've done similar with some older Sony kit.

[osvikvi]

that was my idea as well, I have a whole bunch of those Tandberg TTC08 camera's and wanted to benefit the great optics and PTZ functionality. but only one is working on my Raspi3b+ running Jessie, but can't seem to get a proper videostream on my zero2 running bullseye.

do you have any luck getting a stable image from this HDMI source?

[RogerHardiman]

I use a USB HDMI adapter on a Pi4 (actually a Pi-400 running headless) which is on an older Jessie OS release (or maybe the Bullseye legacy release)

The HDMI image was fine. I just need to capture at a lower resolution (set via v4l2ctl I think) as grabbing at full resolution overloads the USB data bus and eats too much CPU reading the raw image in.

[osvikvi]

Success, I could manage to get a decent image STREAMING 1080p @2fps HDMI over usb In rposConfig.json set "RTSPServer" : 2, In camera .js,: disable the line that prevents from using MPromonet server ('yxzusbcam') (this.config.CameraType == 'usbcam') set resolution and framerate to 1920 x 1080

start the server and go!

it's not really stable, i do loose the signal from time to time... ..trying to figure out how to control v4l2...

[RogerHardiman]

that's great news

[osvikvi]

Thanks, I think so too ;D... It's all in camera.js I could enable verbose logging on the bottom and apparently the server still pushes 25fps while higher up, I requested only 2fps. setting -F 2 again helps. Now the stream is stable.

            this.rtspServer = utils.spawn("v4l2rtspserver", ["-v", "-P", this.config.RTSPPort.toString(), "-u", this.config.RTSPName.toString(),"-F", "2", "-W", this.settings.resolution.Width.toString(), "-H", this.settings.resolution.Height.toString(), "-t", this.config.CameraType, "-d", (this.config.CameraDevice == "" ? "auto" : this.config.CameraDevice)]);
