Question

FMS 3.5 extrememly slow stream/buffer

Hi All,

First, apologies about my nickname - I tried everything under the sun and kept getting rejected, so I just mashed the keyboard and it worked.

Anyway, I'm a complete noob at Flash Media Server. I installed it on my development PC and it worked out of the box with VOD, but when I install it on our live server (Windows 2003 Standard SP2), it is so slow to buffer anything, even on the local network, it takes 45 minutes just to play the sample video.

Can anyone suggest anything I can look at to see why it would be taking so long? The server is a Dual-Quad-Core Xeon with 8gb of RAM, so I don't think it's the hardware at fault (the development server is a Core 2 Duo with 3gb of ram and it was perfect).

I've looked at the logs, and it looks like the following:

session connect 2009-01-21 16:19:40 1032 127.0.0.1 3073 3073 - - - - 200 -

stream play 2009-01-21 16:19:40 1032 127.0.0.1 3160 3451 sample1_1000kbps.f4v 0 14129426 112.384000 200 -

As you can see, each "log" only has about 500kb of data in it...

Regards,

Mark

    Odd indeed. I've only tried streaming the sample videos, and the 3-hour FLV. I might try your suggestion when I get back to work (Saturday here) to see if videos in any other formats stream successfully.

    It's interesting to note that when I watch the admin console, it detects the session, but the bandwidth stays on 0kbps, with the occasional spike up to about 1mbps.

    Yeah... that does sound odd. Does this happen with all h.264 videos, or have you gotten some to play smoothly? Also, are you able to stream VP6 encoded video without issue?

    Hiya,

    I suspected it might have something to do with the metadata in the video, however, this is even happening with the sample videos! And when I play the video on my local machine it's all A-OK, starts streaming within about 5 seconds.

    But even the 150kbps sample video that comes with FMS takes forever to stream, even when viewing on the local server.

    Sounds to me like the atom is at the end of the file (or the file is fragmented with multiple atoms). If the atom is not at the beginning of the file, the whole thing has to be read before the video can start playing.

    There are some tools on the Adobe site to process your file to get the atom in the right place.

    Try running the file through the f4v post processor:

    Hi Techeye,

    It's the same thing. It takes forever. It doesn't matter where the source/destinations are.

    We have a 3 hour video we're trying to stream over it, and I left it for over an hour and I got about two frames out of it, when I was on the local server.

    What happens when you try to play it back locally on the server?
