Description

Hi,

I have a working MotionEyeOS on RPi 3b and a second MotionEye install on Rasbian 10. With both versions the attached USB cam (a PS3 Eye) works fine, but I can't get the RTSP added correctly. I think it has something to do with the characters in the URL which might not be escaped properly and therefor part of the URL gets dropped. Some info:

uname -a

Linux domoticz 5.4.61-v7+ #1339 SMP Tue Sep 1 18:45:30 BST 2020 armv7l GNU/Linux

cat /etc/debian_version

10.10 motionEye Version | 0.42.1 Motion Version | 4.2.2 OS Version | Raspbian 10 Camera is http://www.escam.cn/product/66-en.html RTSP stream URL is syntax as: rtsp://10.6.3.57:554/user=admin&password=&channel=1&stream=0.sdp?

I tried to add the camera as: rtsp://10.6.3.57/user=admin&password=&channel=1&stream=0.sdp? (blank field for user/pass in GUI) rtsp://10.6.3.57:554/user=admin&password=&channel=1&stream=0.sdp? (blank field for user/pass in GUI) rtsp://10.6.3.57:554/channel=1&stream=0.sdp? (filled fields for user/pass in GUI) rtsp://10.6.3.57:554/channel=1&stream=0.sdp (filled fields for user/pass in GUI) and all the above with single and double quotes, but the GUI doesn't accept quotes so you can't add the stream that way.

Log: [1:ml1:Camera1] [WRN] [ALL] mlp_retry: Retrying until successful connection with camera [1:ml1:Camera1] [ERR] [NET] netcam_rtsp_open_context: Normal resolution: Unable to open camera(Camera1): Server returned 4XX Client Error, but not one of 40{0,1,3,4} [1:ml1:Camera1] [ERR] [VID] vid_start: Netcam RTSP failed to open [1:ml1:Camera1] [ERR] [NET] netcam_rtsp_open_context: Normal resolution: Unable to open camera(Camera1): Server returned 4XX Client Error, but not one of 40{0,1,3,4} [1:ml1:Camera1] [ERR] [VID] vid_start: Netcam RTSP failed to open [1:ml1:Camera1] [WRN] [ALL] motion_init: Could not fetch initial image from camera [1:ml1:Camera1] [WRN] [ALL] motion_init: Motion continues using width and height from config file(s)

Does anyone have a clue why this could be happening? VLC plays the stream correct, but I've already read that VLC is very forgiving and motion(eye) and ffmpeg aren't... Should I escape the question marks and/or ampersands for instance?

Cheers!

Research direction
Examine the motionEye source code in the camera configuration module to understand how RTSP URLs are passed to the motion daemon. Look for any URL encoding or sanitization steps, particularly for special characters like '&' and '?'. Review the six existing comments in the issue for any hints or attempted solutions. If possible, reproduce the issue with a known working RTSP camera to confirm the bug.
