Question

FMS Static HD Video Playback buffering issues

HELP!

I have downloaded and installed the Flash Media Server (FMS) trial version.  Just purchased the software today and waiting for the activation serial number. 

I created a video gallery - http://www.usedgymequipment.com/videos3.cfm

My goal is for these videos to stream just like vimeo.com

I am only using HD 1280 x 720 video. All videos are between 25 to 125 MB in size, originally .mov files converted to .flv using FFMPEG.  Videos are between 30 seconds to 58 seconds in length.

I am using ColdFusion to upload and organize my videos and I have configured FMS to work with CF.

The Issue is that these videos buffer the same way they did when I didn't have FMS installed. Press play, the video buffers, the video plays, then stops to buffer again. Stop and Buffer, Stop and Buffer.  I can understand if there is buffering at the start of the video but not throughout.  When I start the video over from the start, it has to buffer all over again!

I cant get any help from Adobe when I call for support, they just re-direct me to call some one in LA that never answers his phone.  So any help or point in the right direction would be much appreciated.

    What bitrate did you encode the flv files at, and how much bandwidth is available at the server side and client side? Constant buffering often indicates that the video is encoded at a bitrate higher than the network can handle.

    The bitrate is set like this:

    <cfexecute name = "#ffmpegPath#"
        arguments = "-i ""#inputFilePath#"" -y -b 15000k -f flv -ar 44100 ""#ouputFilePath#"""
        timeout = "0">
    </cfexecute>

    so - 15000k

    My server's current bandwidth is set at 40mbs, I will be upgrading to 190mbs in 48hrs.

    One other issues is also "smart seeking" or "trailing buffer"

    I need to be able to have  it where the videos buffer and the buffer stays in the memory after the video has played
    so you can jump to any part of the movie (seek). Right now, after a video buffers completely, if you just move the play timeline back to the start, the video will start to buffer all over again.
