Plan 9: Share Media Content with TV via UPnP


 

Share media content with UPnP / DLNA capable players.

This is a proof-of-concept of network programming (TCP and UDP) in Plan 9. For information, man udp is a useful place to get started.

 

Device Quirks

VLC

VLC looks for "urn:schemas-upnp-org:service:ContentDirectory:1" instead of "urn:schemas-upnp-org:device:MediaServer:1" during M-SEARCH.

 

LG WebOS TV 

LG WebOS TV needs the services "urn:schemas-upnp-org:service:ConnectionManager:1" and "urn:microsoft.com:service:X_MS_MediaReceiverRegistrar:1" in addition to "urn:schemas-upnp-org:service:ContentDirectory:1" in device.xml. 

It also seems to remember the UUIDs for a particular IP address. If you change the UUID of our application and it doesn't appear in the TV, restarting the TV might help.

Plan 9 : The Infinity Notebook

  Plan 9 is an Operating System (OS) from Bell Labs which is a successor to UNIX. It builds on the learnings from the previous Operating systems. Network computing and graphics is an integral part of the OS rather than an afterthought. It is modular and portable - it comes with a cross compiler . It is available, under MIT License , which anybody can use, learn and tweak. Features Everything is a file. Singular Grid: All the computers running Plan 9 OS and connected together act like a singular grid. So there's no need for remote access solutions like VNC or RDP. This cool video shows a small glimpse of the possibilities. Process Isolation: Processes run within their own namespaces and are isolated from each other. So you can run rio (the window manager) within rio. Applications like Browsers don't need complicated sandboxing. And a crashing program is unlikely to bring down the OS. No DLL Hell : Binaries are always statically linked. So there's no DLL hell and there...
