Jetson Nano password issue

[luizvaz]

We had a viseron setup working fine with a ubuntu machine running docker. After moving the setup to a Jetson Nano, the cameras didn't connect.

After trying FFmpeg we changed the password. Voila!

The password was something like "blablah!" with an exclamation mark. After changing it to a command-line friendly password it worked.

To make sure it works, I checked if FFmpeg can successfully connect to the stream like this:

ffprobe -v debug -show_error "rtsp://viseron:12345abc%@192.168.0.123:554/Streaming/Channels/102"

I hope it helps!

Could you explain a bit more what your issue is? Is the problem that you cannot use a password with special characters for your camera?

[luizvaz]

Yes, my camera was something like 12345Abc! with an exclamation mark. After changing the camera password to a command-line safe password it worked.

[roflcoopter]

Will see if i can escape the password somehow to allow for special characters

[roflcoopter]

I tested this just now with the password 123!123! and it worked fine for me, not sure if something has changed Closing this, please feel free to reopen if it is still an issue, and if you do have issues please provide the log so i can troubleshoot since i cant replicate
