| ===== Player Program ===== | ===== Player Program ===== | ||
| + | Mplayer has well support for LIRC, but we still need do some work to make it functional like a music box. We intend to make mplayer scan some specified directory (on Cubieboard or network-sharing directory), picking out those supported music files, like ape, flac, mp3, ogg etc., and play them in a shuffle way. Here goes the shell code snippet. | ||
| + | <code bash> | ||
| + | #!/bin/bash | ||
| + | # start_mplayer.sh | ||
| + | # Set this line in your case. A play.list file will be created in this directory, so make it writable. | ||
| + | MUSIC_PATH="/data/share/music" | ||
| + | PLAY_LIST="play.list" | ||
| + | MUSIC_TYPES="mp3 wav ape ogg flac"; | ||
| + | |||
| + | if [ ! -e "${MUSIC_PATH}/${PLAY_LIST}" ] || ( [ $# -gt 0 ] && [ $1 == "rescan" ] ); then | ||
| + | echo "" > ${MUSIC_PATH}/${PLAY_LIST} | ||
| + | for music_type in $MUSIC_TYPES ; do | ||
| + | find ${MUSIC_PATH} -type f -iname "*.${music_type}" >> ${MUSIC_PATH}/${PLAY_LIST} | ||
| + | done | ||
| + | fi | ||
| + | |||
| + | mplayer -lircconf /etc/lirc/lircrc.conf -vo null -shuffle -playlist ${MUSIC_PATH}/${PLAY_LIST} | ||
| + | </code> | ||
| + | Assign this script with an executable bit, and test it. | ||
| + | # chmod +x start_mplayer.sh | ||
| + | # ./start_mplayer.sh rescan | ||
| + | If mplayer is starting playing the music, good to go. | ||
| + | |||
| + | ===== Run LIRC with mplayer ===== | ||
| + | You can test LIRC with mplayer right now, with //**irexec**//, a convenient tool for running programs via LIRC. | ||
| + | # irexec -d /etc/lirc/lircrc.conf | ||
| + | Now, press your IR remote key, enjoy the music comes from Cubieboard. | ||
| + | |||
| + | If you would like the program running in a daemon style, add the fowlling line into //**/etc/rc.local**//, right before "exit 0". | ||
| + | <file> | ||
| + | sudo /usr/bin/irexec -d /etc/lirc/lircrc.conf | ||
| + | ## If there is no "sudo", irexec won't work, which is weird. | ||
