Convert rtsp: stream to ???

I have a cheap IP web camera, that provides a stream that looks like this:
This is openable in VLC, but not RS.
I can setup VLC under linux or Windows to convert and re-stream, but I've been unable to find a combination that works.

While posting this, I did get it figured out somewhat, thanks to this page:

Here is the command under windows that works for me:
vlc.exe -R "rtsp://" --sout "#transcode{vcodec=mjpg,vb=2500,scale=1.0,fps=10,acodec=none}:standard{access=http{mime=multipart/x-mixed-replace; boundary=7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8888/videostream.cgi}

Then on RS, I put in:

I just need to run one copy of VLC per camera, to re-stream so RS can understand it.

It takes a good amount of CPU-  Totally pegs a dual core VM, 10-15% of a 12 core hyperthreaded desktop.

Any chance of directly supporting the rtsp protocol, or is that too much trouble for too little effort?



  • That is too much trouble. I would need to include vlc or ffmpeg to do exactly your conversion. So it does not really gain anything except that you do not set the command. But then I would need to add configs.

    Interface shows webcam using img and that does not support rtsp not would I know how to split that into multiple streams.

    Most IP cams also support mjpg natively. Have a check here

    and see if you find your webcam. It contains a link generator for jpg/mjpg images.
  • I have a similar issue. The TP-Link Tapo C-200 cameras have some great features and the picture is also great, but rtsp only, there is even no http/web interface on them. 

    If I wanted to use the Tapo for timelapse videos, I would need to add the and url to a static image. Let us assume I would be able to get a JPG from RTSP on the same computer that is running the server. Can I point to a local file? Or do I need to have some sort of server running on localhost? I have the nginx installed and working, if that is of any help. Thanks.
  • You need always a web url. But with nginx you could add a host with some port that points to the directory where you save it and use that as url. But that means many writes and if we talk about a pi bad for sd card, so use a ramdisk as target in that case.

    Maybe you can do it with ffmpeg which can convert a lot. But can't say if it works and what cpu usage that would cause.
  • I am running the server on a HP T620 controlling 3 and in future 4 printers over USB. So this looks like a possible solution. I will definitely not do timelapse videos for every print, it is more likely to make one and then forget about it:)
