Запись нескольких радиостанций.

Потребовалось вести запись нескольких радиостанций. Были куплены три автомобильных приемников с линейным выходом, со склада взят старый комп и в него воткнули две старых pci звуковых карты.

1. Установил debian и установлены дополнительные пакеты:
icecast2
darkice
alsa-base
streamripper

2. Настраиваем звуковые карты с помошью amsamixer
3. Настраиваем icecast2, там все стандартно. Добавляем в автозагрузку используя update-rc.d
4. Настраиваем darkice, тут интереснее (почему и родилась статья).

4.1. Создаем три конфигурационных файла:
# cat /etc/darkice.cfg | grep -v ^# | grep -v ^$ | grep -v ^\ *#
[general]
duration = 0 # duration of encoding, in seconds. 0 means forever
bufferSecs = 1 # size of internal slip buffer, in seconds
reconnect = yes # reconnect to the server(s) if disconnected
[input]
device = hw:0,0 # OSS DSP soundcard device for the audio input
sampleRate = 44100 # sample rate in Hz. try 11025, 22050 or 44100
bitsPerSample = 16 # bits per sample. try 16
channel = 2 # channels. 1 = mono, 2 = stereo
[icecast2-0]
bitrateMode = abr # average bit rate
format = vorbis # format of the stream: ogg vorbis
bitrate = 128 # bitrate of the stream sent to the server
server = 127.0.0.1
port = 8000 # port of the IceCast2 server, usually 8000
password = mypass # source password to the IceCast2 server
mountPoint = radio1 # mount point of this stream on the IceCast2 server
name = Radio 1
description = Radio1
genre = my own # genre of the stream
public = yes # advertise this stream?

# cat /etc/darkice2.cfg | grep -v ^# | grep -v ^$ | grep -v ^\ *#
[general]
duration = 0 # duration of encoding, in seconds. 0 means forever
bufferSecs = 1 # size of internal slip buffer, in seconds
reconnect = yes # reconnect to the server(s) if disconnected
[input]
device = hw:1,0,0 # OSS DSP soundcard device for the audio input
sampleRate = 44100 # sample rate in Hz. try 11025, 22050 or 44100
bitsPerSample = 16 # bits per sample. try 16
channel = 2 # channels. 1 = mono, 2 = stereo
[icecast2-0]
bitrateMode = abr # average bit rate
format = vorbis # format of the stream: ogg vorbis
bitrate = 128 # bitrate of the stream sent to the server
server = 127.0.0.1
port = 8000 # port of the IceCast2 server, usually 8000
password = mypass # source password to the IceCast2 server
mountPoint = radio2 # mount point of this stream on the IceCast2 server
name = Radio 2
description = Radio2
genre = my own # genre of the stream
public = yes # advertise this stream?

# cat /etc/darkice3.cfg | grep -v ^# | grep -v ^$ | grep -v ^\ *#
[general]
duration = 0 # duration of encoding, in seconds. 0 means forever
bufferSecs = 1 # size of internal slip buffer, in seconds
reconnect = yes # reconnect to the server(s) if disconnected
[input]
device = hw:2,0 # OSS DSP soundcard device for the audio input
sampleRate = 44100 # sample rate in Hz. try 11025, 22050 or 44100
bitsPerSample = 16 # bits per sample. try 16
channel = 2 # channels. 1 = mono, 2 = stereo
[icecast2-0]
bitrateMode = abr # average bit rate
format = vorbis # format of the stream: ogg vorbis
bitrate = 128 # bitrate of the stream sent to the server
server = 127.0.0.1
port = 8000 # port of the IceCast2 server, usually 8000
password = mypass # source password to the IceCast2 server
mountPoint = radio3 # mount point of this stream on the IceCast2 server
name = Radio 3
description = Radio 3
genre = my own # genre of the stream
public = yes # advertise this stream?

4.2. Создаем пользователей darkice, darkice2, darkice3

4.3. Скрипты запуска (стандартный не может запускать несколько копий под разными пользователями):
# cat /etc/init.d/darkice

Аналогично для darkice3.

4.4. Добавляем скрипты в автозагрузку используя update-rc.d

5. Скрипты для записи.
$ cat rec.radio1.sh
#!/bin/sh
DATE=`date +%Y-%m-%d_%H-%M`
cd /home/air/radio1
/usr/bin/streamripper http://127.0.0.1:8000/radio1.m3u \
-a /home/air/radio1/$DATE -A -s -z -l 3720 -i --quiet
/usr/bin/find /home/air/radio1 -name "*.ogg" -ctime +35d -delete

$ cat rec.radio2.sh
#!/bin/sh
/home/air/radio2
DATE=`date +%Y-%m-%d_%H-%M`
/usr/bin/streamripper http://127.0.0.1:8000/radio2.m3u \
-a /home/air/radio2/$DATE -A -s -z -l 3720 -i --quiet
/usr/bin/find /home/air/radio2 -name "*.ogg" -ctime +35d -delete

Аналогично для rec.radio3.sh

6. Прописываем cскрипты записи в crontab
$ cronatb -e
# m h dom mon dow command
59 * * * * /bin/bash /home/air/rec.radio1.sh
59 * * * * /bin/bash /home/air/rec.radio2.sh
59 * * * * /bin/bash /home/air/rec.radio3.sh

Все 🙂
