Streaming media files via DLNA/UPnP

I'm currently running Raspbmc on my Raspberry Pi and activated UPnP streaming an rendering.

My goal is to write a simple Python to stream a video or music playlist.

I've tried Coherence, but I it's throwing a bunch exceptions and I don't really get the point as the documentation is pretty chaotic. So I'm looking for an easier way/library.

What's the easiest way to stream media files to my TV using Python?

I've had success with nano-dlna, and its source code is rather straightforward too: it serves the file you want to play over HTTP, then issues SetAVTransportURI / Play calls on the specified DMR (DLNA renderer) endpoint.

For audio only, I got good results with rygel. The tricky part is to configure the GstLaunch pulseaudio connector in the .config/rygel.conf. Here is my section, but you can get the right pulseaudio source with the following command:

pactl list | egrep -A2 '^(\*\*\* )?Source #' | grep 'Name: .*\.monitor$' | awk '{print $NF}' | tail -n1

Here is my GstLaunch Section:

[GstLaunch]
enabled=true
launch-items=myaudiowav;myaudiompeg

myaudiowav-title=WAV audio on @HOSTNAME@
myaudiowav-mime=audio/x-wav
myaudiowav-launch=pulsesrc device=alsa_output.pci-0000_00_14.2.analog-stereo.monitor ! audio/x-raw,channels=2 ! wavpackenc

myaudiompeg-title=MPEG audio on @HOSTNAME@
myaudiompeg-mime=audio/mpeg
myaudiompeg-launch=pulsesrc device=alsa_output.pci-0000_00_14.2.analog-stereo.monitor ! audio/x-raw,channels=2 ! lamemp3enc target=quality q

There is a lightweight pure python library dlnap which allows playing media on DLNA/UPnP devices in the same local network

You can use GUPnP binding for python through the gi.repository. Search the documentation for GUPnP and GSSDP, GUPnP AV.

You can couple them with something like a mini webserver running django+SQLite database to define a kind of content directory service (CDS) also you can use Gstreamer (a python binding exist called Gst). With those elements you can build a custom server using SSDP for the discovered stuff; from gstreamer you can get metadata about each media item, and can also use "rtspsrc" of gstreamer for streaming.
