Hi!
Ive been running a an external encoder to produce an HE-AAC+v2 stream with
liquidsoap.
I had to patch libshout as well as ocaml-shout, etc and it worked quite well
with aacplusenc (http://teknoraver.net/software/mp4tools/).
Now, since Nero AG released neroAacEnc, which is supposed to be superior in
quality over aacplusenc, I wanted to try that one out.
There isn't much documentation, but neroAacEnc -help gives pretty much
everything you need.
Now I tried with the following configuration among others, using various
encoding option (HE, LC, HEv2), but non of them is giving me what I need.
def highaacenc(_) = "neroAacEnc -hev2 -q 0.5 -if - -of /dev/stdout" end
# AAC+ output
output.icecast.external( restart = true,
restart_on_crash = true,
process = highaacenc,
host = "localhost",
port = 4000,
password = "xxxxxxxxx",
mount = "high.aac",
header = true,
shout_raw = false,
mime = "audio/aacp",
bitrate = 48,
full )
I tried with '-ignorelength', using '-br 48000', as well as '-cbr 48000' none
of that works. Setting shout_raw to true, doesn't help either.
Oddly, the program accepts STDIN by issuing '-if -' but not for '-of' I tried
using /dev/stdout to force output to be to STDOUT. I assume this is the root of
the problem, yet I have no idea how to solve it. The server (Icecast2) is
serving data, but it's not audio, or mangled, at least. Sometimes a player will
play a few sqeaks, before crashing or simply stopping (EOF).
Andy ideas?
