I am unable to play any RTSP-Stream from any XUbuntu/Ubuntu/Debian Live-Stick or my XUbuntu which is running on my Laptop and Desktop.

I have several rtsp-sources:

  • an RTSP-Stream on my local RaspBerryPi (authentication is not needed)
  • a stream from the internet (authentication is not needed)

Both streams can be played with VLC on:

  • my other RaspBerryPi (RaspBerryPi OS)
  • my Windows-Laptop
  • the Android Tablets, my mobil-phone
  • XUbuntu 20.04 Laptop and Desktop-PC

Both streams can not be played with VLC/mplayer/ffplay on:

  • my XUbuntu 21.04 Laptop, XUbuntu 21.04 Desktop
  • with Debian 11
  • Ubuntu 21.04, XUbuntu 21.04 Live-Version (which I have tried to have a clean system)

The problem must be the new base of Ubuntu, the new Debian 11, because there it is not possible too, to open the stream.

I get a error-mesage like this in VLC:

satip debug: try to open 'rtsp://192.168.178.2:8554/video0'
satip debug: connect to host '192.168.178.2'
main debug: net: connecting to 192.168.178.2 port 8554
...
main debug: no art finder modules matched
main debug: connection succeeded (socket = 37)

satip error: Failed to setup RTSP session
main debug: net: connecting to 192.168.178.2 port 8554
main debug: connection succeeded (socket = 36)
access_realrtsp warning: Cseq mismatch, got 1, assumed 0
access_realrtsp debug: rtsp connected
access_realrtsp warning: only real/helix rtsp servers supported for now
main debug: no access modules matched
main debug: dead input
qt debug: IM: Deleting the input

I have tried it with mplayer, vlc (3.012 in the Pi and Linux, the App version is 3.3.4 ), ffmpeg ... but the result is the same.

This means, the problem is not VLC.

Are ports blocked in Ubuntu/Debian or is there something special I have to do, so that I can play rtsp-steams?

Please note that Debian VLC builds do not support RTSP by Debian policy decision. Use the Flatpak if you need RTSP.

Maybe "use the Flatpak" or "Snap, but not .deb's" helps.

Using snap package

As the other answer said, problem is that RTSP was disabled on the default Ubuntu/Debian VLC versions because liblivemedia constains non-free code. Read more about this on: Debian Bug report logs - #982299 RTSP streams are not displayed with version 3.0.12 on Debian Sid. So, to play RTSP streams, you need the snap package, not the one installed by the apt.

Remove the apt version

sudo apt remove vlc
sudo apt autoremove

Install the snap version

sudo snap install vlc

Play the stream

vlc rtsp://192.168.178.2:8554/video0

Troubleshooting

If you are still getting errors (that was my case), you may need to restart your machine:

sudo reboot
