I have a buildroot based image from which I can successfully stream.
On boot up RkLunch.sh runs and I can connect with VLC on: rtsp://192.168.1.206/live/0

I can then stop the streaming service with RkLunch-stop.sh:

RkLunch-stop.sh
Stop Application ...
killall: udhcpc: no process killed
rkipc exit
ls: /oem/usr/etc/init.d/S??*: No such file or directory

However, if I try to restart streaming the system hangs

Code: Select all

Is there a way of safely stopping and restarting streaming?

Hello. Using RkLunch.sh and RkLunch-stop.sh is a relatively safe way to start and stop the streaming program rkipc. By default, RkLunch.sh will be executed once when starting. If it is executed repeatedly, errors may occur due to resource allocation issues. Please check if automatic execution of RkLunch.sh has been disabled.
