The TV and Radio Ganino promotion for easier success uses Darwin Streaming Server (DSS) by Apple. Darwin Streaming Server (DSS), was the first open sourced RTP/RTSP streaming server. It was released March 16, 1999 and is a fully featured RTSP/RTP media streaming server capable of streaming a variety of media types including H.264/MPEG-4 AVC, MPEG-4 Part 2 and 3GP.

Rachael Bond Saturday, 26 June 2010 Linux

The instructions have now been updated for Ubuntu 12.04 LTS. Homepage for DSS is http://dss.macosforge.org/ also tested on Linux Mint 14

Ensure that you having the following dependencies installed:

~$ sudo apt-get install gcc g++ make patch

You can download the latest version of the Darwin server package from Apple.

~$ wget http://dss.macosforge.org/downloads/DarwinStreamingSrvr6.0.3-Source.tar
or:
~$ wget http://www.ganino.com/files/DarwinStreamingSrvr6.0.3-Source.tar

To additional patches are required to use Darwin on Ubuntu and a custom install script.

Once again, if you prefer to download straight to your server use either:

~$ wget http://www.ganino.com/files/dss-6.0.3.patch
~$ wget http://www.ganino.com/files/dss-hh-20080728-1.patch

Before installing Darwin create its user and group (hyphen may to be change from – to -):

~$ sudo addgroup -system qtss
~$ sudo adduser -system -no-create-home -ingroup qtss qtss

Next unpack the .tar file:

~$ tar -xvf DarwinStreamingSrvr6.0.3-Source.tar

and apply the two patches:

~$ patch -p0 < dss-6.0.3.patch
~$ patch -p0 < dss-hh-20080728-1.patch

Move into the Darwin directory:

~$ cd DarwinStreamingSrvr6.0.3-Source

and delete the Install file:

~$ rm Install

Download the new Install file:

~$ wget http://www.ganino.com/files/Install

and change its permissions:

~$ chmod +x Install

For Ubuntu 12.04 it would appear that there is a compiling problem. This can be resolved by editing line 8 in Makefile.POSIX (in DarwinStreamingSrvr6.0.3-Source) and changing it from:

LIBS = $(CORE_LINK_LIBS) -lCommonUtilitiesLib -lQTFileLib

to:

LIBS = $(CORE_LINK_LIBS) -lCommonUtilitiesLib -lQTFileLib -ldl

After this Darwin can be built:

~$ ./Buildit

and install:

~$ sudo ./Install

To allow Darwin to run automatically on boot, download either:

~$ wget http://www.ganino.com/files/darwin-streaming-server

and change its permissions:

~$ chmod +x darwin-streaming-server

Move this file into /etc/init.d:

~$ sudo mv darwin-streaming-server /etc/init.d/darwin-streaming-server

and then update rc.d to autostart it:

~$ sudo update-rc.d darwin-streaming-server defaults

Darwin requires the ports TCP: 554, 1220 and UDP: 6970-6999 open in order to work. If you are using Shorewall edit /etc/shorewall/rules and add these lines:

ACCEPT net fw tcp 554 ACCEPT net fw tcp 1220 ACCEPT net fw udp 6970:6999

Finally direct your browser to http://yourserver:1220 to check that Darwin is working and to enter your admin passwords. If your server is going to be exclusively for RTSP streaming then select port 80 for use by Darwin – otherwise leave blank as this will interfere with Apache.

You are now ready to upload .mp4 and .mov files for streaming…. however, make sure that your .mp4 files have been correctly encoded and hinted.

Broadcasting a professional image ensures success and easier acceptance. It is accessible from any device that has internet anywhere and at anytime globally. Keep broadcasting.

Encoding is key, encoding videos to specifications that server expects. For example encoding video in h264 and audio in aac. You will need to re-encode all files so that they are identical in every way. I use Wondershare Video Converter Ultimate.

The profile is Mp4:

Video Codec: H.263 Audio Codec: AA2 Video Size: Bit Rate 512Kbps (means every user that downloads the stream at 512kps will get smooth video, the server must also be able to stream @ 512kbps to every user.

After re-encoding you must hint the video. The file will not play until you hint the file.

~$ apt-get install gpac

will provide the MP4Box command

~$ MP4Box -hint thefiletohint.mp4

a check on the video will now show the rtp streams section that a non-hinted video does not have.

~$ ffmpeg -i file-we-require-info-on.ext

To extract Audio From A Video Using ffmpeg

~$ ffmpeg -i “whatever.format” -vn -ac 2 -ar 44100 -ab 320k -f mp3 output.mp3

starting the server point your browser to

http://www.ganino.com:1220

to access the stream use standard rtp port

rtsp://www.ganino.com/tv.sdp

to access the mp3 stream

http://www.ganino.com:8000/radio

SELinux and Firewall will not let it through. Disable SELinux for this test by editing /etc/SElinux/config and setting it to disabled. /etc/init.d/iptables stop to stop the firewall, later adding the exceptions rather than disabling.

QuickTime Streaming Server 4 and Darwin Streaming Server 4 use the following TCP ports:

• 80: HTTP
• 554: RTSP
• 6970 -9999: used for dynamic (announced) UDP broadcasts
• 7070: RTSP
• 8000, 8001: MP3 streaming
• 10,000-20,000: buffer space
• 20,000-65,535: static SDP default range (user defined)

the comments relating to chkconfig are important as chkconfig will read them regardless of the hash usually meaning comments are ok to disregard.

$ chkconfig --add myscript 
$ chkconfig --level 2345 myscript on 
$ chkconfig --list | grep myscript

/etc/my.cnf bind-address = 127.0.0.1 skip-external-locking This also prevents MySQL from listening on the external network interfaces; note: the skip-external-locking directive should be used instead of the deprecated skip-locking.

As a first step after basic configuration, we then need to install the default databases, change the password of the MySQL root user (don't take my passwords as an example!) and answer a few questions:

# /usr/local/bin/mysql_install_db [ … ] # /usr/local/bin/mysqld_safe & [ … ] # /usr/local/bin/mysql_secure_installation [ … ] Enter current password for root (enter for none): <Enter> OK, successfully used password, moving on… [ … ] Set root password? [Y/n] Y New password: root Re-enter new password: root Password updated successfully! [ … ] Remove anonymous users? [Y/n] Y … Success! [ … ] Disallow root login remotely? [Y/n] Y … Success! [ … ] Remove test database and access to it? [Y/n] Y - Dropping test database… … Success! - Removing privileges on test database… … Success! [ … ] Reload privilege tables now? [Y/n] Y … Success!
