+Con el docker de rtmp no acaba de funcionar.
+Pero con este software si. Paramos el docker y descargamos este software:\\

+Lo descomprimimos y lo ejecutamos:
+  ./mediamtx

-Levanto un servidor de RTMP y lo paso a RTSP
+Y ahora emitimos el vídeo al servidor rtmp:
-  ffmpeg -i rtmp://<ip_del_servidor>:<puerto>/<stream_key> -f rtsp rtsp://localhost:8554/mystream
+  ffmpeg -re -i video.mp4 -c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k -bufsize 6000k -c:a aac -ar 44100 -b:a 128k -f flv rtmp://localhost:1935/stream/test
+Y creamos el proxy:
+  ffmpeg -i rtmp://localhost:1935/stream/test -c:v copy -c:a copy -f rtsp rtsp://localhost:8554/live
+Ahora podemos configurar OBS en la dirección:
+  rtsp://localhost:8554/live
