tapo annoyingly is also one of the only cameras that doesn't have a still snapshot url after all these years and endless requests from many

someone needs to make replacement firmware

ffmpeg can fake it but takes a few seconds to grab from the video stream and of course you can't run ffmpeg from your browser (or wait, can you now?)

     ffmpeg -rtsp_transport tcp -i "rtsp://cameraname:camerapass@192.168.1.23:554/stream1" -an   -y  -vframes 1 -f image2 -vcodec mjpeg  "snap.jpg"
