Linux Audio Streaming / Icecast
Omdat linux en audio nog steeds ZUIGT en de documentatie OOK heb ik hier zelf maar een info dump plek :-)
VLC en streaming faalt ook hard omdat je geen deugelijke info kunt achterhalen/instellen.
Korte versie :
ICECAST - Server
DARKICE - Client
ALSAMIXER - Instellen input
INPUT :
root@ACK:/etc/icecast2# arecord --list-devices
**** List of CAPTURE Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 2: ALC662 rev1 Analog [ALC662 rev1 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Live [SB Live! Value [CT4832]], device 0: emu10k1 [ADC Capture/Standard PCM Playback]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Live [SB Live! Value [CT4832]], device 1: emu10k1 mic [Mic Capture]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Live [SB Live! Value [CT4832]], device 2: emu10k1 efx [Multichannel Capture/PT Playback]
Subdevices: 1/1
Subdevice #0: subdevice #0
root@ACK:/etc/icecast2#
Als je de line in van de SBLive wil hebben, kies je in dit voorbeeld hw1:0, de rest gaat uit van dit device.
Met alsamixer kun je record devices en niveau instellen
root@ACK:/etc/icecast2# alsamixer -c 1 -V capture
Met spatie kun je device kiezen en met pijltjes volume instellen
ICECAST
Als je zelf streaming server wil draaien
apt-get install icecast2
info/handleiding volg
((standaard config /etc/icecast.xml))
DARKICE
Streaming Client
Nodig om line in door te zetten naar icecast server.
apt-get install darkice
Er is een gui-iets genaamd darksnow, maar die is oud en geeft geen juiste config.
Gebruik man darkice.cfg voor de commandos/opties
Starten :
darkice -v 10 -c <config>
