After a long time working on private projects and without post, im back. Now I'm working on gmyth library and gmyth-stream server with Arthur, gmyth-stream is a nice project to provide you access your desktop media using your 770/n800 the server will convert requested file to resolution and format necessary for being able to play on your device. Eg. you can watch you HD movie in your device, the server will make a stream of hd movie contents and convert to device format. Now I'm working in gmyth-stream gstreamerer plug-in because the server will work with another tools like memcoder.
