Karl,
Despite what has been suggested, this will still only have a chance of
working work for some flash Movies written in a certain way. Many of my
flash movies are only one frame, sometimes just a handful of frames, so your
attempt to smoothly run a high-bandwidth movie on a slow connection would
fail for movies like mine - either because they load a lot of assets at a
particular frame, or because they load assets via code during the movie.
Either or both of these scenarios would default your mechanism.
Maybe I have missed this somewhere - is a pre-loader out of the question?
Paul

Anthony,
I am going to have to buy you a steak dinner for all the input you have
given me. (unless your vegetarian, then make it a shiitake steak)
Your input is right on the money. ;)
You basically have said what I was trying to, but my lack of terminology
and experience made it sound like some unfathomable procedure.
The only thing is your getting it backwards on how my movie was going to
play. Oh and I am talking about a Flash swf movie (not video
necessarily). The theory about sending some sort of packets to the server
and bouncing back what an how to play the swf is what this is really
about now that I have read your reply. Thanks. My theory was to set up a
code to read the stream of data coming in to the browser, interp. it,
talk to the swf and play the swf faster (skipping frames as you
suggested) if the connection was slow and playing at regular frame rate
when the stream was good. Never playing slow. That is exactly what I am
trying to defeat. The skipping of frames or increase in fps, which may
produce the same, was to give the effect that nothing had happened when
presented with a slow connection. But, I see what you are saying with
combining with a server language to implement it. Maybe coldfusion? I
don't think that PHP could handle that, but, I know PEARL could. But I
would like to see a flash server engine sometime in the near future.
Something that launched and controlled your own applications for your
website and/or a built in flash database.. hello Adobe!!! I wouldn't
even mind a component for that... :P
Thanks again,
I think your suggestion has put me on the right path.. once again. :)

Hi Karl,
The only way to make 30fps play consistently on a lower bandwidth
connection, would be to send a message to the server, telling it to send
the stream at a reduced quality; thus, the size and quality of each
frame would be greatly reduced on a slow connection. Yet, if a pause is
acceptable, creating a buffer for the content and playing the buffered
content, while waiting for new content to download and be placed in the
buffer for later playing, would be an option. Your suggestion, sounds
like it would result in you playing the stream in slow motion.
Another idea would be to tell the server to reduce the amount, or
"drop", the frames sent; yet, this would not be 30fps, as the fps would
drop based on the users connection.
E.G. if 30 fps plays well on 300KB downstream, but the user can only
download solidly at 100KB, you could only send approximately 1/3 (maybe
less to be safe) of the frames safely allocated for that second while
ensuring no delays in matching frames to audio; therefore, frames
1..4..7..10..13..16..19..22..25..28.. would be sent per second out of
the regular 30fps. (I hope I am not missing something and sounding
stupid here)
This is really just theory, and is easier to say than to put into
practise; yet, it is not so difficult to figure out, that you couldn't
pull it off if you were somewhat decent with a server side language like
php and know how to manipulate files by searching for index of frame
identifying start and end keys in the hex to flush out as video stream.
When I say it sounds so easy; yet, making it stable enough not to crash
a server with multiple simultaneous connections might be something
different. Now that I think of it, can php even handle this? or would a
c module be needed to make things run totally stable?
I know this won't really help other than to see why your logic is off,
and maybe give you some ideas of how video is really transfered; yet, I
hope you can make use of it. I have worked a little, very little, with
video in the past; thus, I am not an expert, so if anyone has any ideas
that would make my statements look stupid, I hope he or she will speak
up.
Thanks,
Anthony Pace

How would you equate bandwidth with FPS?
Seems to me that a loading Movie will need to load different assets at
different times, so You may need 100K loaded at one frame followed by
no new assets until 200 frames later when 150K needs to be loaded for a
particular frame.
How can you possibly balance the load?

Close. I am trying to basically see if I can control how fast my movie
plays according to the type of stream it is receiving. If slow on
bandwidth play faster, if normal or high bandwidth play at normal fps.
So that when their is low bandwidth while loading page, the user never
knows or sees it. No "lag" if you will.

I'm pretty confused by your requested, so I've probably got this
wrong.
You're trying to slow down a playing movie because it's not
streaming it's content fast enough to play at the true frame rate?

Sorry I guess I was not clear on my first post, but I am looking to
find out how to ready how much stream I am getting and adjust my
frame rate of the movie (swf) accordingly. Main part of my question
is to figure out how to get the stream info so to be able to adjust
the FPS to it. Better?? Thanks for any input.
Anthony, thanks for the FPS link, that will come in handy.
BTW I am still coding in AS2 for this project.

i am not necessarily asking about just a moviclip but the whole

Hope that clarifies.

First you say swf, and yes, controlling the frame rate for an
swf is doable; yet, then you say movie... do you mean movie
clip, or stream?
Karl DeSaulniers wrote:
Ok here is a new one. Is there a way to control the way your
swf plays according to the bandwidth it's getting?
For eg: control how fast FPS your movie plays according to the
stream of info it's getting from the server? If the stream is
low play fast and if the stream is good then play regular fps?
All of this to simulate "no lag".
