Comment(by romeodeepmind):
i have occasionally discovered that faad decodes aac+ streams and started
to test it.
now i'm checking such setup
this is the main script. it recieves aac+ stream from sam broadcaster and
steams it to icecast and harbor input of the other script
{{{
%include "/home/vko/conf/settings.liq"
set("server.telnet",true)
set("server.telnet.port",8091)
set("harbor.bind_addr","0.0.0.0")
set("harbor.port",8090)
set("harbor.password", playlistPasswd)
system(liveScript)
################### [Callbacks] ###################
def liveStart(headers)
log("[LIVE-START]: live source goes up! Switching from playlist...")
system(liveScript ^ " " ^
quote(headers["ice-name"]) ^ " " ^
quote(headers["ice-description"]) ^ " " ^
quote(headers["ice-genre"]) ^ " " ^
quote(headers["ice-url"]) ^ " " ^
quote(headers["ice-bitrate"]) ^ " " ^
quote(headers["ice-audio-info"]) ^ " " ^
quote(headers["content-type"]) ^ " " ^
quote(headers["user-agent"]))
title = headers["ice-name"] ^ " | " ^
headers["ice-description"] ^ " | " ^
headers["ice-genre"]
log("Live-meta: " ^ title)
ignore(server.execute("liveMeta.insert title=\"#{title}\""))
end
def liveEnd()
log("[LIVE-END]: live source goes down! Switching to playlist...")
system(liveScript)
end
def playlistStart(headers)
log("[PLAYLIST-START]: playlist source goes up! Switching from
noise...")
end
def playlistEnd()
log("[PLAYLIST-END]: playlist source goes down! Switching to
noise...")
end
################### [Live Sources] ###################
#Live Sources
liveInput = input.harbor(
id="live",
liveMount,
buffer=harborBufferSize,
password=livePasswd,
on_connect=liveStart,
on_disconnect=liveEnd
)
#make source active
output.dummy(mksafe(liveInput))
liveInput = insert_metadata(id="liveMeta", liveInput)
################### [Playlists] ###################
playlistInput = input.harbor(
id="playlist",
playlistMount,
buffer=harborBufferSize,
password=playlistPasswd,
on_connect=playlistStart,
on_disconnect=playlistEnd)
#make source active
output.dummy(mksafe(playlistInput))
################### [Noise] ###################
noiseInput = noise(id="noise")
noiseInput = amplify(id="noiseAmp", 0.05, noiseInput)
noiseInput = rewrite_metadata([("title","no signal")], noiseInput)
################### [Master Input] ###################
#Master Input
input=fallback(
id="mainFallback",
track_sensitive=false,
[liveInput, playlistInput, noiseInput]
)
################### [Mount Points] ###################
out_aacplus(
masterHost,
masterPort,
masterMount,
masterPasswd,
masterBitrate,
input
)
out_aacplus(
"localhost",
8092,
masterMount,
masterPasswd,
masterBitrate,
input
)
}}}
second script polls icecast stream via input.http (now with disabled
metadata)
{{{
%include "/home/vko/conf/settings.liq"
################### [Input] ###################
input = input.http(
masterUrl,
new_track_on_metadata = false
);
input = mksafe(input)
################### [Output] ###################
out_aacplus(
masterHost,
masterPort,
"rvk32a",
masterPasswd,
32,
input
)
}}}
third script recives stream from the master script via harbor
{{{
%include "/home/vko/conf/settings.liq"
set("harbor.bind_addr","0.0.0.0")
set("harbor.port",8092)
set("harbor.password", masterPasswd)
################### [Input] ###################
input = input.harbor(
id="live",
masterMount,
buffer=harborBufferSize,
)
#make source active
input = mksafe(input)
output.dummy(input)
################### [Output] ###################
out_aacplus(
masterHost,
masterPort,
"rvk64a",
masterPasswd,
64,
input
)
}}}
i hope to find out in what situation faad fails.
but if you say it supports only aac streams - that could be a reason of
segfaults
