Hello all,

i am now running a test server to stream audio that csound generates.
The streaming server is publicly accessible by using
VLC player (http://www.videolan.org/vlc/) or TuneIn Radio (http://tunein.com/get-tunein/)
at mms://54.248.254.55:8080/ (mms: should be changed to mmsh: if you use VLC player for Linux).
Feel free to access it to listen :-)

On Ubuntu Linux and Android 4.1, VLC Player works fine to play the sound.
On Windows7, you have to wait for a minute or so for VLC Player to start playing the streaming.
(i do not know why. Is there some negotiation before receiving data?)
On iOS and Android, TuneIn Radio seems to work fine to play the mms streaming.

The server also accepts interaction via OSC if you use
andOSC (https://play.google.com/store/apps/details?id=cc.primevision.andosc) .
In andOSC setting you need to set IP as 54.248.254.55 and Port as 56789 (same as default).
By drawing some patterns on the screen of andOSC you can modulate the sound in semi-realtime (with latency of seconds),
as the csound csd file is designed to receive the Touch data from andOSC.

# At NIME2013 i will present some demonstration using part of this as a way of sonification of access log of a Web-based tool.



FYI, following is how you can set up the steraming server using Ubuntu 64bit 12.04 Server.
In the server, Csound, Jackd and VLC are installed and used.

sudo apt-get update
sudo apt-get -y install csound
# Following libs are used by csound
sudo apt-get -y install liblo7 libfltk1.1 libportmidi0 libportaudio2 libfluidsynth1
sudo apt-get -y install jackd2 vlc-nox vlc-plugin-jack
# During installation of jackd2, just press Enter (use default configuration).

jackd -d dummy &
csound myfile.csd &
cvlc -v 'jack://channels=2:ports=.*' --sout-keep --sout '#transcode{acodec=mpga,ab=128,channels=2,samplerate=44100}:std{access=mmsh,mux=asfh,dst=:8080}' &

# i am using an Amazon EC2 micro instance. In that case, you need to set accessible TCP and UDP ports like
# Security Groups - Inbound : All TCP and All UDP. (Do not forget to click Apply Rule Changes after clicking Add Rule)

Very interesting! Thank you!
As I mentioned before, this could be used for educational purposes to
showcase csound, without the need to install it.
One could think of an intertactive web-GUI to make changes to the .csd
file...

To add to the non-streaming csound server that has been active for years.
Perhaps it is time to take this version down

Wow!

That's great! I could listen to the sound from commanline with 
 
mplayer mmsh://54.248.254.55:8080/

(opensuse linux) without any problems.

Thanks for the tips about the cSoundServer!

Hi,

could you give us the list of message addresses and types, and ranges accepted by your server, so we
could try using any OSC (e.g. csound) controller?

Regards

Victor

Hi Richard and John,

Thank you for your ideas.
Though it is a kind of dirty quick hack, i set up another server:
http://54.247.70.51/csound-or/
This can accept a csd file (that does not require user's GUI operation) from anyone to be streamed.


For setting up a server like this,
in addition to the installation i mentioned in my previous mail, you need:

sudo apt-get install apache2 php5
# run jackd and vlc as the same user of php process
sudo -u www-data jackd -d dummy &
sudo -u www-data cvlc -v 'jack://channels=2:ports=.*' --sout-keep --sout '#transcode{acodec=mpga,ab=128,channels=2,samplerate=44100}:std{access=mmsh,mux=asfh,dst=:8080}' &
# see the Jack port name of VLC (to edit $VLCportname in conv.php)
sudo -u www-data jack_lsp  | grep -i vlc

Full description is found in readme.txt in the zip file ('php code' link).

Oh, i missed that point.

Is there any quick way to disable possible holes, for example with a command line option or something?
Or must i recompile csound?

for avoiding malicious command by system opcode, i am now thinking to run csound as a user with more limited permissions.

i found a quick way.
i just removed these two libs:
/usr/lib/csound/plugins64-5.2/libpy.so
/usr/lib/csound/plugins64-5.2/libsystem_call.so

After that, i checked pyinit and system opcodes result in error.

Thank you for pointing out the security problem! > Andrés

Hi tarmo,

Yes, i use mplayer too on my Ubuntu.
mplayer is nice as it accepts --cache option to adjust the time lag due to buffering.
i am thinking about somehow introducing audience interaction as inspired by what you did in the concert in Hannover.

Hi,

Thank you for checking.

i am also curious about how one can receive and play the streaming on MacOS.

At least delete libsystem.so to remove the system opcode

wrt python, the default is not to byuid them.

I think the python opcodes are in libpy.so but I am not totally sure.  I
would recommend deleting that library

==John

Yes, i found that, and deleted
/usr/lib/csound/plugins64-5.2/libpy.so
/usr/lib/csound/plugins64-5.2/libsystem_call.so

After that, pyinit and system opcodes fail. Now the security problem seems fixed.
Thank you very much for your advice, John.

Hi Oeyvind,

i am not sure how many clients it can serve.
it seems at least 5 clients at the same time are OK for this case (micro instance is the least powerful server).
i think that totally depends on the server performance and network bandwidth at the server side.
If i get a more powerful server and network, more clients can connect to it.

Amazon EC2 is one of the most popular services providing cloud computing servers.
http://aws.amazon.com/ec2/
That is 'Linux machine in a minute', your own virtual linux machine that you can make and throw away anytime.
so it is the best for this kind of experimental purposes.
The pricing in this case (micro instance) is 0.027 US$ per hour, that is approx. 20 US$ per month.

If you make some mistakes in setting up a server, you can just delete it and create a new one.
What you have to pay for is the time duration (in hours) of only the running servers (not of stopped nor deleted servers).

Of course, you can setup this kind of streaming servers using your own computers at your university or home.
