change the resolution of the video

You can change the resolution for v4lrtspserver like this:

/system/sdcard/bin/v4l2rtspserver-master -W 640 -H 360

Depending on which way you start the rtsp Server you can add the paramters in run.sh or in /system/sdcard/controlscripts/rtsp-h264 or /system/sdcard/controlscripts/rtsp-mjpeg

If autostart is disabled in the config, the rtsp-server gets started by /system/sdcard/run.sh When you start the rtsp Server via the "Manage Scripts" Website, the Server started by run.sh is terminated and the one from /firmware_mod/controlscripts/rtsp-mjpeg oder rtsp-mjpeg is started
