Subject: [Icecast] static noise while streaming
Message-ID: <18143.17069.441226.766620@hetman.ua>

Hi all,

I'm very new to audio streaming, so please excuse my ignorance.

I'm using icecast2 server and muse source client on gentoo linux. Some
mp3 files that I'm streaming exhibit severe static noise, in fact, the
noise is present always but is most noticeable for the records that
are currently playing,

http://24.57.213.147:8000/aha.m3u

(I'll keep this alive for a while)

I don't know where to start looking for causes of the problem. Is it
muse?.. icecast? Thank you for any hints. If more info is needed, let
me know.

Thanks,

Icecast does not change the encoding so check the source client. If the 
original material does not have the problem then you'll know what is 
causing it.

Thanks a lot Karl for the prompt reply.

What I suspected, something is wrong with encoding in muse... Their
website looks very much abandoned but I'll try to get some help there.

I had some hardware trouble earlier in the year, so there was a pause, 
however there has been various updates to my branch work (moved to 
http://www.icecast.pwp.blueyonder.co.uk) and many of them have worked 
out well.

Over the last few weeks I've been filtering some of the updates and 
merged them into trunk so feel free to try the trunk code. Tarballs are 
available at http://people.xiph.org/~brendan/snapshots/icecast/

Hi

I'm new to this list, so please forgive me if I ask a dumb question!

I know that AACplus is a dirty word here but....

I'm trying to make comparisons between live streams of OGG and AACplus at
different bitrates. The only way I've found of streaming AAC+ so far from
Linux is by running Winamp under wine and sending this to my Icecast2
server. This sort of works, but is hardly optimal!

Ezstream is my preferred way of doing this (hopefully using the Linux
neroAacEnc coder) but there is no support as yet in the distributed version
of ezstream. Has anyone managed to get anywhere in putting AAC+ (MPEG2
container I guess) support into ezstream? Of course Ezstream works great
with OGG, but I'm not so happy with the OGG quality at q=-2 compared to AAC+
at 32kbps as far as I've got in my tests so far. Music is not too bad but
voice seems pretty rough and rings and echoes a lot. I'm using
oggenc-aoTuVb5 with ezstream, however Winamp has only got aoTuVb4.

Thanks

Subject: [Icecast] playlist generator
Message-ID: <195F195F-6E73-4BFF-87C8-0C9D0479A92B@unaradio.com.ar>

Hi,

I've been doing some scripts to generate playlist through some rulesets
They are written in php, but run from the command line.
I've used em with ices and sc_trans

the script takes an xml configuration file with a list of folders,  
each with some priority, and makes a shuffled playlist with songs  
from higher priority folder having more chances to play than others.

I put very high priority to an "Announcements" folder and get my  
announcements playing every 3 or 4 songs.

the features i've been thinking of adding are:

-adding a specific hour to some folders, making them play at that time
-adding a no-shuffle setting so that a folder runs in the exact order  
it has inside
-an expiration engine, which allows some songs or folders to stop  
playing after some specific date/time
-having the system id every file and counting how many times each  
song plays in a mysql or flat file db
-being able to set up the system so it rotates the songs, avoiding  
repetition
-set up announcements to run at specific intervals
-a user feedback mechanism so that listeners can vote for or against  
a song, which will add or remove points from a song and from a  
folder, which will count in the priorities for playlist generation (i  
currently have one folder per dj, so 12-15 djs add music in their  
folders, with the voting, popular djs will have more air time than  
others)
-artist cloud generation for the website, with a list of most played  
artists of the last weeks

the features will probably be split in several different commands,  
following unix fashion

if anyone has interest on helping, or has suggestion for other  
features, mail me

thanks
nicolas

Subject: [Icecast] libshout: shout_get_error() returns SOCKET ERROR
Message-ID: <BAY111-F2694E6344F18E657AB0CB9DDBD0@phx.gbl>

Hello

I've configured the 'example.c' with the right SERVER, PORT, SHOUT FORMAT 
and all the required stuff, it works fine (the setup shout_set...() calls) 
but when reaching shout_open() it returns a socket error.

$ ./example
Error connecting: Socket error

The configuration of the server and example.c is right, at least the server 
is up and running, and tried it with the winamp/shoutcast and the linux 
shoutcast transmitter and it works...

What can be the problem? I thought it could require root UID to work but not 
it still don't work. Am thinking it could be the kernel headers/structures, 
am using Linux with kernel 2.6.18 and libshout 2.2.2

Don't know if the mailing list supports libshout, but didn't find nothing in 
the forums, sorry if it is not the right place for my problem.

Regards

The beauty of Ezstream is that it shouldn't require built-in support for 
these sorts of things.  It uses external encoders and decoders to get the 
job done, which in theory should mean that it can support anything.

I'd not heard of this encoder, so took a look at it.  You'll need to do a 
few things to get it to work, but it should be able to.

first, Ezstream reads and writes data in raw PCM format.  The docs don't 
seem to say which format though.  I'm going to assume 44.1kHz 16-bit stereo 
for these examples.  You might also have issues with byte order, if you 
hear loud static then you'll need to swap it somewhere.

since neroAacEnc seems to only support reading in wav file formatted audio, 
we need to convert it on the way in.  sox can do this nicely.

sox -t raw -r 44100 -c 2 -s -w - -t wav -

We can write this in a slightly simpler way:

sox -t sw -r 44100 -c 1 - -t wav -

Then we can pipe it into neroAacEnc.  NeroAacEnc can be told to take audio 
from standard input, though curiously it can't be told to send it to 
standard output (we'll have to do that via /dev/stdout).

sox -t sw -r 44100 -c 2 - -t wav - |neroAacEnc <options> -ignorelength -if - -of /dev/stdout

As I mentioned, if you hear loud static then you'll need to swap the byte 
order.  This is done by using the -x option to sox on the input side.

You need to use -ignorelength because raw PCM data carries no length info 
so sox won't be able to supply a meaningful value for the length field in 
the wav header.

NOw you have the line for including in the encode section of your encdec 
stanza.  Decoding is a similar process - we'll need to decode to wav then 
convert to raw PCM.  But we won't need to specify sample rate or channels 
as these will be included in the wav header.  If you need to swap the byte 
order, it goes on the output side of the sox command.

I can't provide an exact line as the readme only provides usage for the 
encoder and the built-in help doesn't seem to work, at least for me.

Then all you need to do is create a stanza like the ones in the sample 
config, telling ezstream how to encode and decode your format.

The only reservation I have about all this is that the impression I get is 
that the audio will be in an MP4 container.  Is this what you want?  I'm 
not real up on all this new MPEG stuff so am not sure what the implications 
are of this.

Since you can plug in any kind of encoder/decoder, I'de thought that you'd 
be able to use something from the faac project.

I've not tried it in a while, but have you tried downsampling to 32kHz?  It 
may improve things with little noticeable difference.

I was thinking about this one.  It occurs to me that ogg bitstreams contain 
timing data (similar to timecode).  You could develop a player that used 
this ogg-based timecode in conjunction with accurate PC clocks to develop 
some kind of sync protocol (matching ogg timestamps to time-of-day).  I 
guess you would have to have a master/slave setup where one system was 
authoritative and others would sync to it.  I guess you could also have 
mechanisms where the master was declared unsound if say it lost the stream, 
and another master would be "elected" or something.

The parallels I see here are the ways that MIDI sequencers and audio 
devices can sync with SMPTE et al.  It's used in video too I think.

Of course, you would have to have accurate time, but NTP is capable of very 
good time-keeping.  YOu'd also have to be able to ensure the same latancy 
for the actual playing of the audio... but that's more complex than I'm 
qualified to speculate on.

Geoff.

Just curious why such an old version of Icecast?  The current version is 
2.3.1 and that's been out for awhile.  You can get a precompiled binary at 
http://downloads.xiph.org/releases/icecast/icecast2_win32_v2.3.1_setup.exe 
and sources at 
http://downloads.xiph.org/releases/icecast/icecast-2.3.1.tar.gz

There's also a newer libshout - you can get 2.2.2 from 
http://downloads.us.xiph.org/releases/libshout/libshout-2.2.2.tar.gz

Hope this helps.

Geoff.
