Since multicast is used, this can be executed on multiple -soundbox devices to stream to all of them. +Audio can be streamed to \texttt{soundbox} devices with the \texttt{ffmpeg} +command. Audio files or internet stream addresses can be passed as input. \begin{verbatim} - ffplay udp://224.0.0.99:5316 +ffmpeg -re -i <input> -acodec libmp3lame -f matroska \ + udp://224.0.0.99:5316 \end{verbatim} -As soon as the soundbox is listening the stream can be send from another -computer in the same network with this command: - -\begin{verbatim} - ffmpeg -re -f lavfi -i aevalsrc="sin(400*2*PI*t)" \ - -acodec libmp3lame -f matroska udp://224.0.0.99:5316 -\end{verbatim} - -It will send a simple sine wave with 400~Hz to the soundbox device. -Alternatively a MP3 file can be sent like this: - -\begin{verbatim} - ffmpeg -re -i <file-path> \ - -acodec libmp3lame -f matroska udp://224.0.0.99:5316 -\end{verbatim} - -These commands allow to test the \texttt{soundbox} device setup. +More details about FFmpeg streaming can be read from the FFmpeg streaming +guide\footnote{\href{https://trac.ffmpeg.org/wiki/StreamingGuide}{https://trac.ffmpeg.org/wiki/StreamingGuide}}. \chapter{Production} |
