I've been studying UPnP/DLNA media servers and have written my own media server from the ground up
My reasons for this is speed, my server has over 50,000 files on it and all commercial upnp applications use internal databases that are quite frankly "slow" so mine uses Microsoft SQL server for its database storage
As a comparison, When doing a search, tvMobili takes 9 seconds to return 1000 results, mine takes less than a second and overall works a lot faster with media players
So far Audio is working perfectly and streams very nicely, but im having problems with video, avi's just refuse to stream and players try to download the entire file before playing anything
I've read on a few forums that there are issues when streaming avi files, i must admit i should know more than i currently do (partly why i'm here)
But before anybody tells me that it "cant" be done, please take this into account tvMobili CAN do it, i just want to know how....
One thing i've noticed is that Windows media player makes 2 requests when starting a file (audio or video)
The first request is for the file eg. /stream/12345.mp3
The second request is a little different eg. /stream/12345.smi
I think the .smi extension holds the key, internet searches tell me its a subtitle file, but i think UPnP servers use it differently
Has anyone heard of this extension or is able to give me any clues to its format?
Here are the the 2 sets of headers that media player sends when opening an mp3 file
GET /stream/27776.mp3 HTTP/1.1
User-Agent: NSPlayer/12.00.7601.17514 WMFSDK/12.00.7601.17514
GET /stream/27776.smi HTTP/1.1
Accept-Encoding: gzip, deflate
Can anyone shed any light?
Thanks in advance
