Error: gst_rtsp_server_attach_failed

[Moodsh00]

Trying to get rtsp stream from hi res camera of sentinel voxl2. I dont have doodle labs or 5g. Can someone please help as im getting above error. Camera server connected. The pc is connected direct to voxl wifi. In rtsp-streamer it seems to get 0 from gst rtsp server attach after creating rtsp server main loop source for callback. Cannot find any info online to get past this.

Hi @Moodsh00 ,

Have you tried using voxl-streamer ? This would be the preferred way of using gst

Thanks for reply. The error message referred to is actually from voxl-streamer. I enter the shell; then type voxl-streamer. It responds saying:
using config file etc/modalai/voxl-streamer
Camera server connected.
ERROR: gst rtsp server attach fail

If you run voxl-inspect-cam -a do you have hires showing up?

Can check out this config file: /etc/modalai/voxl-streamer.conf

Here's hires example config: https://docs.modalai.com/voxl-streamer/#high-resolution-hires-camera-example

Yes it shows up. 480X640 with 11.90ms exposure and gt =2

It also shows up fine in the web portal

I figured it out this weekend. It had to do with a swap file in streamer config. I deleted the file and rtsp showed up. However now im trying to get rtsp stream quality to match the quality on voxl portal. Its really grainy. I tried the config files in streamer at 1920X1080 and increased the bitrate by a factor of 5. Will try the camera server today.

Also; is there a way to stream to both vlc and gcs at same time. The feed cuts when i try a second viewer.

Lastly; is there a way to keep the rtsp stream connected to gcs from bootup. It seems like when i close the shell; the rtsp stream to gcs gets lost.

Many thanks again.
