Hi,
Motion JPEG (mjpeg) isn’t supported in Wowza; you have to use h264. Check if the camera can send h264 instead of MJPEG. If not, you may use separate software to convert from MJPEG to h264. You can read an article about conversion options here: MJPEG to Wowza
Don’t hesitate to contact me if you need help with the configuration.
Kind Regards,
