Doods person deception RTSP camera Pi4

Hi All,
I’ve been having a play doods on my Pi4. I can only get RSTP stream from my cameras, the only way I have found to make this work is to use Motioneye and then stream the video from Motioneye out as Mjpeg, this works, but Motioneye eats the CPU is there another way to convert RTSP to Mjpeg

my Cameras are EZVIZ Mini O Plus ( Yes I know but I already have them)
