One time, I must deal with sound on some area in specific time.
\nSo I created a raspberry based server, which runs, control’s and deal with radio stream. I used rpi1 – raspberry 1.
\nMaybe this can help someone.
\nFirts, we download Raspbian Jessie Lite and burn this image on sdhc card (of 2GB capacity at least):<\/p>\n

wget https:\/\/downloads.raspberrypi.org\/raspbian_lite_latest\nunzip 2017-01-11-raspbian-jessie-lite.zip\ndd if=2017-01-11-raspbian-jessie-lite.img of=\/dev\/sdb bs=4M\n#make sure, that \/dev\/sdb is your sdhc card, free to format<\/pre>\n
After first use, make some enhacements and customizing:<\/p>\n
sudo tune2fs -c 1 \/dev\/mmcblk0p2\n#this force to check sdhc card every reboot for errors<\/pre>\n
Edit \/ets\/fstab and force to use some log destination to ramdisk and with less write operations.
\nBecause after some time, the sdhc card may fail because of many writing operations on it. In my case, I deal with three bad shdc cards in two years.
\n– option noatime (Do\u00a0 not\u00a0 update\u00a0 inode\u00a0 access\u00a0 times on this filesystem)<\/p>\n
\/etc\/fstab:\nnone\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/var\/log\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 tmpfs\u00a0\u00a0 size=1M,noatime\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 00\nnone\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/var\/tmp\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 tmpfs\u00a0\u00a0 size=1M,noatime\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 00\nnone\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/tmp\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 tmpfs\u00a0\u00a0 size=1M,noatime\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 00<\/pre>\n
Next, I disabled swap, because I didn’t need it:<\/p>\n
dphys-swapfile swapoff\ndphys-swapfile uninstall\nupdate-rc.d dphys-swapfile remove\n#check:\nfree -mh<\/pre>\n
And finally, install some software, create some scripts, to deal with the music itself.<\/p>\n
#I prefer omxplayer\nsudo apt-get install omxplayer\nmkdir \/home\/pi\/stream<\/pre>\n
First script, that will be used in cron:<\/p>\n
cat stream\/script_audio.sh\n#!\/bin\/bash\nif ps x |grep -v grep |grep -c \"omxplayer.bin\"\n\u00a0then\n\u00a0 echo \"everything is ok\"\n\u00a0else\n\u00a0\u00a0\u00a0 echo \"omxplayer missing, starting...\"\n\u00a0\u00a0\u00a0 sh \/home\/pi\/stream\/vlna.sh &\nfi<\/pre>\n
This script starts to play our live radio.<\/p>\n
cat stream\/vlna.sh\n#!\/bin\/bash\nomxplayer --vol -200 http:\/\/stream.radiovlna.sk\/vlna-hi.mp3 &\nexit 0<\/pre>\n
And useful script to kill omxplayer from services and stop playing<\/p>\n
cat stream\/kill_omx.sh\n#!\/bin\/bash\nomx=`ps ax |grep -v grep |grep \"omxplayer.bin\"\u00a0 | awk '{print $1}'`\nkill $omx\nexit 0<\/pre>\n
Every script must have execute permision:<\/p>\n
chmod +x *.sh<\/pre>\n
And use crontab, for enable playing. This option runs script every minute every
\nday in week between 6 am. and 6pm. (from Monday to friday)<\/p>\n
*\/1 6-18 * * 1-5 sh \/home\/pi\/stream\/script_audio.sh &<\/pre>\n
So, if this will help to somebody, i will be happy \ud83d\ude42
\nHave a nice day.
