VLC: transmisión de video desde la cámara macbook iSight (desbordamiento insuficiente del búfer rc)

Question

Estoy intentando transmitir el video desde mi cámara iSight macbook (Retina de 13 pulgadas, principios de 2015, OSX 10.11.5 EI Captain) usando VLC, pero recibo un mensaje continuo de "desbordamiento insuficiente del búfer rc".

$ /Applications/VLC.app/Contents/MacOS/VLC --playlist-autostart --sout='#transcode{vcodec=mjpg,vb=256,fps=25,acodec=mpga,ab=64}:std{access=http{mime="multipart/x-mixed-replace;boundary=7b3cc56e5f51db803f790dad720ed50a"},dst=:[b]8888[/b],mux=mpjpeg}' qtcapture://
