RTSP stream not workning in Windows

[mrXypleX]

Thank you for a realy great program!

but im having problem connection to a rstp camera in Windows
it says "Error: Unable to play stream" and command line output (print) "[ WARN:1@35.335] global cap.cpp:206 cv::VideoCapture::open VIDEOIO(DSHOW): backend is generally available but can't be used to capture by name"

OBS virtual camera is working great, but whit some lag. (due to OBS Studio)

@mrXypleX can you share the entire log? and also a screen of the rtsp dialog?

Unfortunately I've the same problem. Fresh Windows 10, May 2024 installation.

Here is everything I can tell you about the RTSP stream:

It comes from a MediaMTX server (https://github.com/bluenviron/mediamtx), started with this config:

flir.yml.txt

I capture a part of the desktop and stream it via RTSP. It's a window that reads the temperature from a FLIR USB cam. With ScoreSight I want to extract the temperature values and give it somehow to my Home Assistant instance.

ffprobe.txt
scoresight_std_2024-06-17_15-20-57.log
scoresight_2024-06-17_15-20-57.log

VLC is able to open this stream on the same machine without any problems :)

hm
do you have any details about the rtsp stream you're serving? like what encoding etc

[mrXypleX]

its h264 MPEG-4
did a network sniff. cant see a single tcp package from my computer to the webcam. Should at least try to start some sort of handshake... (my windows FW is off btw)

Check the ffprobe.txt :)

[mrXypleX]

ffprobe:
