Progress bar for player?

Question

Hi All,
I am developing a player,
I not able to get how to create a progress bar  which shows download data and the player
Like YouTube which show the download as well as the player head.
Thanks in advance.

Answer 1

if the video is a live stream, it's impossible to do it.
You can't work out your player position or amount downloaded because the end position and total file size are unknown.
I'm guessing you may actually mean you want the progress bars to be live and not manually controlled, in which case you could use a timer

a function you might find useful in doing this would be the PHP filesize function
http://php.net/manual/en/function.filesize.php
you could send off a script at the begging on the stream calculating the total filesize, and then compare that against amount downloaded in you AS3, what would be download progress sorted.
