Streaming video on a NSLU2

    Just got a NSLu2 with a Maxtor One Touch 500 GB attached

    I copied over a 12 GB video file (a straight copy off my MINI DV camcorder) on to that drive

    My intention was to use the combo as a media server.

    I tried to play back the file on my laptop wirelessly but it was extremely slow and jittery.

    Am I using this device in the incorrect manner, or do I need to reduce the size of the files(I can convert these files to divx or mpeg4)

    The nslu2 is not wireless so you have a router/ap in the mix. The slowest bit should be the wireless ~20MB/s throughput but you may have to tweak the basic TCP/IP setting to maintain this throughput with the latency of the devices. Also you should be able to increase buffer size in the video app (I had to dig to find this in vlc recently, to get smooth video from nslu2 to hard-wired PC).

    Thanks mstombs - do you have more information as to where to tweak? I have a WSRT54g(old one, like ver 1.1)

    Just for kicks last night, I tried it from my wired desktop as it was just as choppy

    Thanks!

    For your PC's TCP/IP settings see

    I have in the past 'tweaked' to make full use of internet downloads which need a big Receive Window (RWIN) or else there are pauses where sender waits for an acknowledgement. Shouldn't be needed for lan wired connections, but wireless may use a different set of defaults. Wireless must go through the Router and the Linux OS, but wired on local network should just bounce off the switch in 'hardware', which suggests it is the nslu2 I'm afraid.

    In VLC the caching time is only visible when you tick "advanced options" under

    Input/Codecs -> Access Modules -> File (I also increased FTP, SMB, TCP as not too sure which applies for windows shares!)
