Hi,
Most of my streams are talk, in mono, with
output.icecast(%mp3(samplerate=44100,bitrate=64,stereo=false),...).
However, while preparing the playlists quite a few songs were left in
stereo, which had not been a problem with ls 0.93. We have since upgraded
to ls 1.0.0 which barfs on a mix of mono and stereo streams. As a result,
now our streams are non-functional, and we've been offline over a week.
LS 1.0.0 does not like a mix of mono and stereo files, and will barf with
error 'incompatible number of channels. Having to convert all the stereo
streams to mono manually and upload them is a rather daunting task. Is
there any way of adding some ls code to do this conversion automatically
on a as needed basis (that is, something like 'stereo_to_mono()' when the
stereo programs are called and processed)?
An example where I mean with this program block (under 'b'):
# === MMEL ===
a =
single("/usr/local/www/rcr/mp3/announce/opener/opener-mmel.mp3")
b = playlist.safe(mode="random",
"/usr/local/www/rcr/mp3/music/Phillips/")
mmel = sequence([a,b])
# Fill-in Title for ID3 Tag
def fill_in(s)
# the function f takes a list of pairs m representing
the metadata
# and it maps an anonymous function on each pair
# replacing empty title definitions by title=filename
def f(m)
print("\n\nFor metadata: #{m}\n\n")
list.map(fun (key_value) ->
if key_value==("title","") then
if m["filename"] ==
"/usr/local/www/rcr/mp3/announce/opener/opener-mmel.mp3" then
("title", "Welcome to Morning Melodies")
elsif m["filename"] ==
"/usr/local/www/rcr/radio/current/mp3/today-mmel-mp3.pls" then
("title", "Morning Melodies - see
www.RuralCatholicRadio.com for
details")
elsif m["filename"] ==
"/usr/local/www/rcr/mp3/announce/CLOSER.mp3"
then
("title", "Thank you for listening to
Morning Melodies")
elsif m["filename"] ==
"/usr/local/www/rcr/radio/current/mp3/mmel-mp3-end.pls" then
("title", "Morning Melodies - see
www.RuralCatholicRadio.com for
details")
else ("title", "Morning Melodies - see
www.RuralCatholicRadio.com
for details")
end
else key_value end,
m)
end
map_metadata(f,s)
end
mmel = fill_in(mmel)
Your advice will be greatly appreciated!
