Re: [Flashcoders] FPS question
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.

Re: [Flashcoders] FPS question
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?

You need to use an event listener, (or if it's as2 assign an
onComplete function). Not to be rude, but you should probably go out
and buy a book on ActionScript -- this is a very basic question, and
where I can answer this in depth, it really won't do you much good in
the long run without a good grasp of basics.

Use a timer like this:

function time_tick(e:TimerEvent):void{

Re: [Flashcoders] FPS question
I believe the standard way of handling this is to have three different versions of your movie. low, normal and high quality (how you down the file size is totally dependent on you, could be dropping frames, could be lower rez, whatever). Which one gets loaded in can be determined by connection speed, I think this is pretty much the norm way of doing it, and while Anthony's solution is good in theory, I think it would be too much of a pain in the ars, not to mention a butt load of server-side processing every time a user loads your site. - Taka On Wed, Apr 1, 2009 at 6:44 AM, Paul Andrews p...@ipauland.com wrote: default your mechanism?

Re: [Flashcoders] how can I set the end of a dynamic tween
Sorry Cor,
Don't mean to contradict you, but there is also a
TweenEvent.MOTION_CHANGE event which gets fired whenever the tween
value changes.
Of course, a Timer would work as well.

I guess it depends on what you are trying to achieve.
With the Timer option you could trace every position of the tween and
interact on values.

Hi Coders I have this code, is for a dynamic tween., pretty easy
actually but when the logo hits floor(645 value y) I would like to
have something else, because the logo is a movie clip, there is the
code.
stop();
import fl.transitions.Tween;
import fl.transitions.easing.*;
var ballXTween:Tween = new Tween(logoCacao, y,Bounce.easeInOut,
logoCacao.y,
645, 2, true);
//here is my problem when I try to calculate, when it hits the floor
(645)
if(logoCacao.y=645){
trace(I'm here);
}
it would work with =, but no with = or ==
any ideas, I've been trying to resolve this too much time, I rather
have some fresh ideas or pointer what am I missing.

Well I did, but was a Event.On_Complete, instead of the one you
mentioned later, anyway thanks for your help.

You need to use an event listener, (or if it's as2 assign an

Re: [Flashcoders] how can I set the end of a dynamic tween
Since the Tween ends with y=645, the test is superfluous and also a bit mad
since the easing is set to Bounce, so it may reach 645 more than once during
the course of the motion.

The IF statement is over before your logoCacao is on 645 so it is never

Use a timer like this:

Thanks Taka and Cor, I did the TweenEvent.Motion_Change or

The tween event are not in any part of my book, or should I look

I guess it depends on what you are trying to achieve.
With the Timer option you could trace every position of the tween and

Re: [Flashcoders] FPS question
Hi Paul, I agree. I suggested my methods with regard to movie downloading. Doing what Karl wants with an swf would mean that you would have the capability to isolate frames of the swf server side before sending, and I don't know enough about the swf file structure and how it is read by the player to say if its even possible. Anybody know something I don't about this, which wouldn't be hard, please tell me. Thanks, Anthony Pace Paul Andrews wrote: 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?

(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. :) Karl DeSaulniers Design Drumm http://designdrumm.com On Apr 1, 2009, at 2:50 AM, Anthony Pace wrote: 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
Re: [Flashcoders] FPS question
Hello Taka, I agree with you; as well, with regard to the swf, it would take a ton of in depth knowledge and understanding about its file structure, and how it handles tweens, that I don't have right now, in order for me to say if its even possible.

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
Re: [Flashcoders] FPS question
Back to the original issue at hand. I think that is is definitely not optimal to be relying upon somebody's connection speed/bandwidth to determine fps and/or how to display content. I believe that's why people use preloaders.

Re: [Flashcoders] FPS question
Yes you are correct about the preliaders and the different versions of sites per connection speed. Here is what I am experiencing and why I am lookijng for this solution. I have a preloader on my site and it preloads fine. But even with the preload I still get a lag when it starts playing. There is no way I am building three sites every time I make a site. So I wanted to have a streaming script watch the stream and adjust accordingly so that there would be no lag. I have been to many flash site that load significantly faster than mine and they have more in them. Alas too a lot of my animations are animations and not tween animations. I am not the best coder (as you can tell) so I am relying on animation to suffice. This is not the best practice I know, but bills need to be paid and I have no time to go back to school. I am self taught and so the industry standards on how to do this, I have not been introduced to. I don't mean to sound like the biggest idiot, but in AS I guess I am. Thanks for your input on this.

Re: [Flashcoders] FPS question
Alright, well my two cents is that the problem isn't what you think it is, and here's why: I build a lot of sites and the reason it's chugging is not anything to do with streaming... if you truly do have a preloader, and it does load in 100% before playing, it's not a streaming issue. It seems to be a CPU issue. If the computers with slower connections you are testing on are older computers (which for some reason is usually the case) then it may seem like it's the connection speed, where in fact it is the CPU chugging. The idea that animating on the timeline is x amount slower than doing it through code is a myth that's not true. It is true that you can optimize some thing through code, but unless you're doing some crazy animation stuff then that's likely not the issue either. The proper solution: bring down the cpu usage, which isn't an exact science you'll just have to futz around with things and use common sense, such as using blank keyframes when things are off the stage, making sure you aren't animating a lot of vectors (and if you are use bitmap caching), etc. - Taka On Wed, Apr 1, 2009 at 2:27 PM, Karl DeSaulniers k...@designdrumm.com wrote: Please excuse the auto correction of my email client.
