RTSP cam in octoprint workaround

General
1

Hi guys, I was struggling with rtsp cam in octoprint for some time and today I've found good solution. All is done one machine where octoprint is.

Build this https://github.com/horgh/videostreamer
Then run it

/path/to/Go/bin/videostreamer -input rtsp://camIP/stream_name -fcgi=false -format

in octoprint's settings set cam url to http://octopi_ip:8080/stream

Last step is to modify template at /home/pi/OctoPrint/venv/lib/python2.7/site-packages/octoprint/templates/tabs/control.jijnja2
at line 17 change this

<img id="webcam_image" data-bind="css: { flipH: settings.webcam_flipH(), flipV: settings.webcam_flipV() }, event: { load: onWebcamLoaded, error: onWebcamErrored }, visible: !webcamError()">

to this

<video style="width: 100%" autoplay id="webcam_image" data-bind="css: { flipH: settings.webcam_flipH(), flipV: settings.webcam_flipV() }, event: { load: onWebcamLoaded, error: onWebcamErrored }, visible: !webcamError()"></video>

If you use dashboard plugin you need to modify its template too.

Instead of modifying the code you could use this plugin I wrote that replaces the img tag with an iframe maybe.

That is exactly what i was looking for.
Just got a cheap cam and found out it only supports rtsp and no http streams. Spend quite some time :smiley:
As soon as my print finishes i will try this out.
Really looking forward to this, thanks.

You may want to look over at this post. It is re-encoding rtsp stream into mjpg to work with OctoPrint by default.

I'm really struggeling right now.
Installed everything and it should work.
Which ip should i use? I tried the loopback ip and the ip of my pi.
The rtsp link is correct, i tried it before several times.

I don't know where the problem ist.
The output is always the same:
"Waiting for clients..."
"Starting to serve requests on 0.0.0.0:8080 (Fast CGI)."

I hope you have some suggestions. Thanks!

Hi you have to run it with command i provided
/path/to/Go/bin/videostreamer -input rtsp://camIP/stream_name -fcgi=false -format

Just edit path to compiled videostreamer, camIP and stream name

Ok. It's not a octoprint plugin. As I wrote earlier you have to build it. Please read instructions in that git repo :slight_smile: If it's ok I could help you figure it out via teamviewer later today:)

ohh ok, sorry! I'll try! thanks a lot!

I was also able to use _ instead of & maybe this will help

rtsp://192.168.1.125/user=admin_password=_channel=1_stream=0.sdp?

rtsp://192.168.1.125/user=admin_password=_channel=1_stream=0.sdp?

after tryin to connect within octoprint i only get:

2020/05/03 19:43:41 Serving [GET] request from [127.0.0.1:36566] to path [/] (0 bytes)
2020/05/03 19:43:41 Unknown request.

@igor_quagliato Try it as @nuetim wrote

@nuetim As I can see you are requesting / it should be /stream

( /webcam/?action=stream)?

also tried http://octopi_ip/stream with this i dont even get a request notice
