[Flashcoders] flv lagging when changes the frame via code
Hello all! I'm doing a kind of navigation application using a flv embedded on flash. When I use a command to play it, it runs well.. But if I go to to a specific frame backwards the current frame, it gives a small lag before plays again... Is it a codec restriction? Any way to avoid that lag, using only a big flv, like my situation?

Re: [Flashcoders] flv lagging when changes the frame via code
Hi, might not be your issue, but are you telling the timeline on which the flv is embedded to go back, or the flv itself? greetz JC On Fri, Jul 25, 2008 at 7:18 PM, Fabio Pinatti [EMAIL PROTECTED] wrote: Hello all!

Then, if I play it goes well.. but if in frame 100, I call a gotoAndPlay(50), for example, it backs to frame 50, give a small lag, and then plays. -- Fábio Pinatti :: web.developer www.pinatti.com.br :: 19. 9184.3745 / 3342.1130 ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

I've experienced the same with movies on timelines, and never found a great way to overcome the performance lags.

Then, if I play it goes well.. but if in frame 100, I call a gotoAndPlay(50), for example, it backs to frame 50, give a small lag, and then plays. That's because when you go to a frame that does not contain a keyframe for the movie it has to actually go back in the movie until it finds a keyframe, and re-render it until the frame you want to see. Makes a backward playback impossible, for example. If you just have a few moments where you need it - ie, skipping to the middle of the movie - and you want to make the skipping performance a bit better, increasing the number of keyframes on your movie helps. Just export with 1 keyframe every second and see how it works. This will probably make your movie file bigger. There's no perfect solution, however. The only way to fix it completely is making all frames keyframes, which pretty much defeats the purpose of using a video file. You can only hope that a few more keyframes will work well enough.

I know at least that is not possible do miracles with flv encoding. Thanks so much for clarifying me..
