1. Make sure that much of the video is downloaded first. This is a drawback
of progressive downloaded video.
2. Seek() only works to keyframes. Make sure you have keyframes encoded in
the video at those points.

Subject: [AFFUG Discuss] NetStream and Video Problem
I have recently encountered a problem with the netStream.seek() method.
I have built a video application for my doctoral dissertation that
extensively uses the seek function with a "scrubber bar" and buttons that
allow the user to move through a video in 10 second and 1 minute
increments.
When I pilot tested the application this summer, I used a 20 minute flv
video that was loaded into the application and everything worked just
great. Now I am having problems with the seek() method. When I use the
scrubber bar, or any button to move forward through the video, the video
'snaps back' to a location that is nowhere near where I need it to go.
For example, if I move the playhead position to 23 minutes and 14
seconds, the video might snap back to 9 minutes and 34 seconds and never
allow me to jump to that spot in the video. I have to let the video play
to that spot.
I think that the root of all of my problems is that I have built the
application around progressive downloading of the video rather than
streaming. Now that I am using larger videos of 45 and 55 minutes, this
may be the root of all of my problems. Is this my problem or is there
another aspect that I need to troubleshoot?
Thanks for any help that you can provide,
Kevin Shorner-Johnson
