Is it working with other software like mjpg-streamer?

mdevaev avatar Jun 15 '24 04:06 mdevaev

I honestly don't know how to use mjpeg-streamer. But I for example wrote a script in python and translated it to browser. it works but not for klipper. (but for example in telegram addon the same link works)

Wait a moment. Before you're hitting Ctrl+C, do you have a video stream?

mdevaev avatar Jun 15 '24 09:06 mdevaev

no

Foxius avatar Jun 15 '24 11:06 Foxius

Did you try --debug?

mdevaev avatar Jun 15 '24 14:06 mdevaev

No feedback, closing.

Did you try --debug?
