WSLのUbuntuでPC内の音楽データをGoogleHomeで操作する(shuffle再生)

Last updated at Posted at 2019-09-09

#はじめに
「WSLのUbuntuでPC内の音楽データをGoogleHomeで操作する」のshuffle再生バージョンです。
【追加】2020-5-1
playlist作成とmplayerの再生で同期が取れず、playlistが未作成で再生しようとするので、
setTimeoutで遅延をいれました。
#プログラム(node.js)
●grep検索で抽出した音楽データのプレイリストを作成する。
●mplayerのオプションでshuffle再生する。(mplayer -shuffle -playlist)
●音楽データのリストを予めフリーソフトで作成してください。(list.txt)
