This appears to work, but I'm curious if those of you more familiar with
this scripting see a more efficient solution?
set("server.socket",true)
set("server.socket.path","path/to/socket")
# points to a single blank .mp3 file
silence = mksafe(playlist("./silence.m3u"))
# If there is anything in the queue, play it. If not, play the silence
defined above repeatedly:
radio = fallback([ request.queue(), silence])
# Connect to icecast and play the radio object defined above:
output.icecast(%mp3(stereo=false),
host="192.168.1.1", port = 8000,
user = "test", password = "test", mount = "/test",
radio)
Then, this works to push items into the queue and they appear to play
immediately:
echo "queue.push /path/to/file" | socat ./socket -
So some questions:
- Is there a better in-script way to generate silence until the queue is
populated without having to reference a file?
- Does anyone have any perl, python or php examples for connecting to the
socket that work? Struggling with that.
- Is there any overall better way to accomplish what I'm doing?
- What is the best way to define the meta data for each file I am placing
on the queue?
- Why would I be generating these just looping the blank mp3 file but not
appear to actually be out of sync:
2017/01/21 02:50:44 [clock.wallclock_main:2] We must catchup 43.84 seconds
(we've been late for 100 rounds)!
Some back story:
I am generating audio files off of SDR dongles and each .wav file belongs
to a specific police/fire talk-group. I want to selectively stream certain
files towards a broadcastify.com stream in sequence and if possible I want
to define the metadata with the name of the agency each audio file belongs
to, and some of these transmissions are really brief so defining it in a
timely manner is important.
Thanks
