I just played with streaming a bit the other day on my old P4 storage box at home. Since I have apache on it, I opted to try some streaming of sort so I can access the ripped movies I’ve got stored on there from my Samsung Galaxy Tab.
I used these links to get it done:
Music in general (.mp3, .ogg, .mp4) : http://ubuntuforums.org/showthread.php?t=34359&page=1
Really just notes on what did, so if you’re looking for a howto, follow the links. Or leave a note.
