Raspberry Pi3にmjpg-streamerを入れる - Qiita
https://qiita.com/lobmto/items/c31e0c8136c16f75b1cd■動画の回転

以下のように「-rot 180」を指定すれば、上下回転して表示できる。

$ sudo /usr/local/bin/mjpg_streamer -i "input_uvc.so -f 30 -r 640x480 -rot 180 -d /dev/video0 -q 80" -o "output_http.so -p 8080 -w /usr/local/share/mjpg-streamer/www"
