ActionScript 3.0 :: Performance - Videos Play Slow Using FLVPlayback
Feb 25, 2009
My scene has a video background which scales to the stage size. Then, each section has another video when transitioning in. The problem is that the videos play really slow than they should, very low fps. When there are 2 videos on the stage, it goes even slower. I've tried with embedding videos, using FLVPlayback, wrapping in movieclips, but still the same result. The videos are exported at 30 fps, same rate than the flash movie.
I recorded videos using fms and i want to play them using FLVPlayback component. I've done some research but i cant find somethinguseful, I tried this code :
I've read the reference here,but it seems to me that I can only make it work with live OR recorded videos.How can I make it work with both live AND recorded videos?
I have created an app in CS5.5 for Android and iOS. I have tested on two Android devices and everyingthing works fine. However, on an iPad and iPhone the animations are really slow. Here are some more facts:
1) My project has many scenes and in the problems scene there are upwards of 1,200 frames. But even simple animations run slowly.
2) The frame rate is set for 24 fps.
3) I have created a universal app (iphone and ipad), publish resolution is standard at full screen.
4) Ironically, I have already tried caching as bitmap. That actually slowed my animations even more. I am truely at the end of the line here and don't have any possible solutions.
I have a DataProvider object which loads an XML object during instantiation. I set my datagrid.dataProvider to the DataProvider object. There are 13 columns, and approximately 40 rows.
Scrolling the datagrid, and resizing columns has alot of lag. Is this to be expected when using the DataGrid component with larger datasets?
for the past couple of weeks I've been learning AS3, and for a school project I'm doing a remake of the popular DOS game Liero. Everything is working fine, I got a layer of dirt that I am shooting away, but the problem is that after a few hundred bullets, the game starts to lag heavily whenever a shot is fired.I'm using a simple bitmap and a brush to erase the parts where the bullets hit.
// Drawing stage bmap = new BitmapData(1100,800, true, 0); dispBmp = new Bitmap(bmap);
I have 500 small objects, I would like for them each to rotate (spin) constantly, I have seen a few methods for doing this, but what would be the best way to do this so performance doesn't slow down?
when I create a medium or large text block, Flash (cs4) starts to work very slow, only a objet move or a click on stage takes a lot of time to process. My computer features should be ok... 4gb ram, intel 2 core duo 2.4 hz... The only thing that I think can be a problem is that I'm using Windows Vista 64 bit.
I'm curious when Adobe are going to repair the performance issues inside component inspector panel in CS5? Scrolling through the properties of some components is ridiculously slow, 486 like slow...
I have a Flash movie that runs full screen, but with StageScaleMode.NO_SCALE so that the actual movie size is the same as it would be if I ran it not full screen.
There is a huge difference in performance between full screen and no full screen. This is despite the movie taking up the same screen space.
In a SWF file, when I am using the following code to move backwards to a previous frame, it is incredibly slow -- Taking around 2 seconds. Where as moving forward to next frame takes 30-40 milli seconds.
In terms of performance, does loading .swfs into a flash movie have any implications. I've been experimenting with loading complex swfs into a simple movie and the complex .swf seems to perform a lot slower within the .swf than as a standalone. The host movie has no other funcitonality other than as a simple container. Is it in general terms better not to load .swfs into a movie but to code everything inside 1 movie ?
I am using a custom Flex skin to create an active blur/frosted glass effect on the background of floating Panels, TitleWindows, and other containers (similar to http:url....). There is a background image in the Application skin, and potentially any number of other components above and below the active blur component. Here's some relevant code within the skin:
public static const BLUR_FILTER :BlurFilter = new BlurFilter(16, 16, BitmapFilterQuality.HIGH); private var _bitmapFill :BitmapFill = new BitmapFill; private var _matrix :Matrix = new Matrix;[code]....
Unfortunately, the performance of this when the component is being resized, and especially when moved, is poor. There is noticeable drag delay and overall slowdown, and this is with only one popped-up TitleWindow in the test application. There is especially poor performance when components inside the TitleWindow are changed (button hover states, etc.)I've attempted to optimized a little bit by avoiding reinstantiation of the blur filter, bitmap fill, and matrix, but this has had little or no effect. I removed the blur at one point, just drawing the Application to a bitmap, and the performance is still poor, so it's clear that it's mostly the BitmapData.draw() call.
I've read about using scrollRect and cacheAsBitmap, but I'm not sure where to apply these properties (or other optimizations I'm not aware of) within the Application or its components.
I am building a video player which should load multiple videos in a FLVPlayback. When the loading of the first video has finished, the second one should start, using the VideoProgress Event.
My code looks like this, videos is an array with the paths to the videos:
flvPlayback.addEventListener(fl.video.VideoProgressEvent.PROGRESS, progress); flvPlayback.addEventListener(VideoEvent.COMPLETE, onComplete); private function progress(e:fl.video.VideoProgressEvent):void
[Code]....
Now I have the problem when I test this locally, the first video is invisible sometimes when starting to play. This is not happening everytime, but sometimes the video is not shown, but I can hear the sound, and I can see the scrubber on the seekbar moving.
I already tried to check in the progress function if the video is already playing, and if not, set a timer that will call the progress function again in 1 second.
I am currently working on a project (AS3), where I have 2 frames, with 2 videos (using the FLVPlayback component) and I want to switch from one video to the next video, however the catch is when I switch to the next video I want the new video to play at the previous video time. Example: Video 1 plays, 10 sec later, you click a button to go and see the next video (in another frame) and that new Video starts 10 sec into it.
This is the codes I been using so far: import fl.video.VideoEvent; import fl.video.MetadataEvent; video1.addEventListener(VideoEvent.PLAYHEAD_UPDATE, timer); function timer(e:VideoEvent):void { var newTime = video1.playheadTime; [Code] .....
I imported multiple flvplayback videos on my file via the Video Wizard Import. After that I removed all videos except one. But it's still trying to load those old video and the skin of their player when I preload the file. I am sure there's no player on the stage except the one I need. And when I need to play the file, it's working well, the only problem is the extra loading for 6 skins that I don't use anymore and the time to look for 6 videos that are not there. So here're my questions;
1- When you import a video via Wizard, it there a script hidden somewhere that can be found? 2- When you import a flv to the stage, there's a loading bar saying getting metadata. Is there a place to edit or erase this metadata? 3- Any other ideas of where I could look to find this hidden data or trace or ghost that needs to be remove from the file ?
I'm now working on a flash website, i need to play a youtube video inside my flash movie. In this Flash file i have a FLVPlayback component and i tried to link the youtube video into this but did'nt work.
I'll start by saying that I'm in the process of learning actionscript. That said, I'm wanting to play two videos with actionscript. I went through a tutorial and using a pre-built flash player I used the following script
[Code]....
Which worked fine. That said, that was just a test. We are wanting to use the F4 Player. I opened up the player and looked at the actionscript (which is below). I had some trouble, so I posted on here and this was my response..
I am trying to make a swf with one FLV playback player and 6 buttons. I've got 6 different videofiles that I want to have linked to this swf. Some of the videos are quit large.When starting the Swf, the first video has to start, after playing it, it has to stop. Then you must be able to choose which video to play by clicking one of the buttons. I don't want to have small thumbnails of the video, just plain and simple buttons.I have to have all my files, both fla, swf and xml files in the same directory (I cannot have them stored in different folders, since I have to upload this to a cms system which has limited upload properties).
I've tried to find the right script on the internet, I'm not very good at scripting myselve, actually rather poor educated there.It seems to me that I have to make an xml file with a list of all my videos, I have my default swf ready, with a FLVplayback and buttons.Now there's just the coding part....
If I create a .swf video and then embed it in my webiste the video doesn't play. The placeholder for the flash player is blank on the screen. But if I load a .swf file that is a slideshow or has animation then it plays in the flash player just fine. I am creating in an ASP.net environment using Visual Studio 2008. I have tried everything. I've published using Flash CS4, I've tried using the SWFObject, I ve tried javascript and its all the same. Videos just don't play but any other .swf file will.
i am using soundmanager to order sounds. my site preview, in home page, square shapes comes into stage and you can drag drop them, all shapes binded its own sound. if they are colliding binded song will play.
the problem is i have 3 second timer to control sounds. every timeout i have to stop sound and play again for synchronous issue, that is my solution for that part. but sometimes before loop, there is an annoying little silence.
I had to reinstall my flash cs3. I have downloaded all the updates. But applications I made prior to my reinstall that were playing mp4 videos will no longer work. I keep getting an error in the output window:VideoError: 1005: Invalid xml: URL: "dave boushey video reel_1mb_768k.mp4" No root node found; if url is for an flv it must have .flv extension and take no parametersat

I'm working with flowplayer and accordingly ActionScript. This project has slowmotion plugin, but there are two imperfections: it uses the special stream server and no sound in slow motion. Is there possibility to play flash video and audio in slow motion by just add something in ActionScript?
how to play videos randomly? For example, if I have 5 videos in a flash file, how can I make the player play the 5 videos randomly on every page refresh?
I have created a loading video that plays on top of the main FLV until it is done buffering and then disappears. This should be straight forward, however, it does not work for me.[code]...
