ReadyMedia multicast discovery on bridge iface

When running a ReadyMedia (aka MiniDLNA, but it could be the case for any application using multicast) server on a bridged interface (like br0), multicast_snooping must be disabled on the bridge:

echo 0 > /sys/devices/virtual/net/br0/bridge/multicast_snooping

to make the change permanent:

echo 'net.br0.bridge.multicast_snooping=0' > /etc/sysctl.d/98-minidlna_no_snoop.conf


Install Arista Transcoder on Fedora 18

aristaArista Transcoder (http://www.transcoder.org/) is a useful transcoder tool build upon Python and GStreamer. It’s not available in Fedora yum repositories, but the installation from source is quite easy.

Let’s go.

First: download the sources from its website and untar them

[daniele@sam ~]wget http://programmer-art.org/media/releases/arista-transcoder/arista-0.9.7.tar.gz; tar xzvf arista-0.9.7.tar.gz

Second: install the dependencies required to build and install Arista and the extra GStreamer plugins (if not already installed) via yum

[daniele@sam ~]sudo yum -y install python3-devel gstreamer-ffmpeg gstreamer-plugins-good gstreamer-plugins-bad-free gstreamer-plugins-bad-nonfree gstreamer-plugins-ugly

Arista uses HAL which is deprecated since Fedora 15 and removed from Fedora 16, so to run Arista you also need to install python-gudev which uses udev instead of HAL.

[daniele@sam ~]sudo yum -y install python-gudev

Third: build and install the software and remove install sources

[daniele@sam ~]cd arista-0.9.7
[daniele@sam arista-0.9.7]$ python setup.py build
[daniele@sam arista-0.9.7]sudo python setup.py install
[daniele@sam arista-0.9.7]$ cd ~; rm -Rf arista-0.9.7

Fourth: run Arista from command line or from your application menu!

[daniele@sam ~]$ arista-gtk
