I am seeking for working file output that uses external lame encoder.
That will allow me to use standard ubuntu packages with MP3 encoding
of the archive of my stream.
I wrote something like this:
def output.file.lame(
~id="output.file.lame",
~start=true,
~restart=true,
~append=true,
~restart_delay=3,
~description="OCaml Radio!",
~public=true,
~dumpfile="",
~lame="lame",
~bitrate=128,
~swap=false,
~restart_on_crash=false,
~restart_on_new_track=false,
~restart_encoder_delay=3600,
~headers=[],
~perm=438,
~quality=5,
~dir_perm=777,
~reopen_when={ false },
location,
s)
samplerate = get(default=44100,"frame.samplerate")
samplerate = float_of_int(samplerate) / 1000.
channels = get(default=2,"frame.channels")
swap = if swap then "-x" else "" end
mode =
if channels == 2 then
"j" # Encoding in joint stereo..
else
"m"
end
def lame_p(m)
"#{lame} -b #{bitrate} -r --bitwidth 16 -s #{samplerate} \
--signed -q #{quality} -m #{mode} --nores #{swap} -t - -"
end
output.file.external(id=id,
process=lame_p,
start=start,
append=append,
restart_on_crash=true,
restart_encoder_delay=restart_encoder_delay,
header=false,
perm=perm,
dir_perm=dir_perm,
reopen_when=reopen_when,
location,
s)
end
But it always resamples to 32000 KHz and does not reopens the file
(reopen_when argument). What I had made wrong?
Thank you,
Marcin
