I'm trying to troubleshoot the scrubber for a custom video player and I'm coming across an issue with the scrubber being dragged past the progress bar fill if the flv hasn't fully loaded.
The player is here:
http://mindfilemultimedia.com/stage/portfolio.html
If you play the video you will see that while the flv is still downloading, when you move the scrubber past the yellow progress bar into the white part of the line, the video player will freeze. It is doing that because the user is telling it to seek to a part of the video that has not been fully downloaded yet. What I want it to do is determine if the flv is still downloading and restrict the user to only be able to drag the scrubber up until the width of the yellow progress bar. Right now I have set the code to retrieve the bytesLoaded and bytesTotal and what I want to do is to say something like (in actionscript 3):
if (videoPlayer.bytesLoaded < videoPlayer.bytesTotal) {
var newBounds:Rectangle = new Rectangle(0, 0, (videoPlayer.bytesLoaded/videoPlayer.bytesTotal) * MovieClip(root).SeekBar.SeekProgressBar.width, 0);
MovieClip(root).SeekBar.SeekBarHandle.startDrag(false, newBounds);
}
I am by no means an actionscript person, so that was my attempt at doing what I needed. I have a feeling that it is not working because I'm accessing the classes incorrectly for the progress bar and the scrubber handle, but I am just taking the default classes as the seekbar was a flash components. Well, I can just be completely wrong. Any help here would be appreciated.
Where are you putting this code? It needs to be put somewhere, where it is updated regularly. Depending on what type of video player you were using you could see what events it dispatches and use an event listener to regularly check how much has been buffered. You could also use the enter frame event although you would need to make sure you stopped listening once the buffer is complete as it would add extra overhead on every frame.
As a side note SeekBar and SeekBarHandle should probably be seekBar and seekBarHandle respectively, as it's standard practice to start instance names with a lowercase letter in actionscript.

OK, I have seen a lot of questions and answers on how to code pause/resume buttons, but none of them fit my specific need. First let me explain what I have:
I have made a tutorial video for my job. It consists of screens shots and sounds. I have a forward button that skips to the next section (usually the start of the next audio file) and a back button that goes to the previous section. However I need a pause button.
Now let me explain how I have built it:
I have made the movie at 1fps. I have a layer for Audio, a layer for the screen shots, a layer for each button, and various other layers for highlighting things in the screen shots. On the Audio layer I placed my audio file on the stage and then dragged out the number of frames until the entire audio file could play uninterrupted. So if the audio was 10 seconds long, it lives across 10 frames. I can then put my screenshot on its own layer and do the same so that the image displays the same length of time as the audio. When the frame ends, it automatically skips to the next frame and continues on until the end. Since the audio is on the stage, the viewer doesn't need to do anything to get the audio to play.
After viewing many tutorials, it seems like most people use code to get the audio to play rather than putting it on the stage. I am not this skilled.
So my question is, with my current set up, how can I make a toggle button that basically says "If audio is playing, stop the whole show when clicked- if audio is not playing, resume show from last position when clicked"?
Thank you so much if you can help! Also, this is my first time asking a technical question like this, please let me know if you need any other specific details.
First make sure all audios on your timeline are set to "Stream". To
do this click on the frame where your audio lies, find the sound
panel, change it from Event to Stream. this will ensure that when
the timeline is stopped the audio stops and resumes when the
timeline is played.
As for the buttons simply make one that calls stop() on the timeline and one that calls play(). This will stop the timeline wherever it is and resume it on play.
var myTimeline:MovieClip;//link to the movieclip where your timeline animation lies
var btnPause:SimpleButton;//link to your pause button
btnPause.addEventListener(MouseEvent.CLICK,function(event:MouseEvent):void{
myTimeline.stop();
});
var btnResume:SimpleButton;//link to your resume button
btnResume.addEventListener(MouseEvent.CLICK,function(event:MouseEvent):void{
myTimeline.play();
});
I am playing audio through the background audio player agent. How do I display a progress bar in the foreground indicating what position is the track currently add, like the built-in music player.
At Rob Crocombe blog you can find how to make a progressbar and use it with Background audio player. It works basing on Dispatcher Timer, which you start along with play button - the music is playing in background, timer is working in main UI and it's updating progres bar.
On the other hand, if you want want to make a slider (to be able to jump to selected position) you can use (as it's showed in blog) SuperSlider from Toolkit or you can customize your own slider as it showed here.
I done this same using Media element there i used a progressbar and Dispatcher timer on dispatcher timer tik event i updated the status of progress bar
Windows Phone Background Audio with Slider and Timer

So, I'm pretty much a beginner in Flash and Actionscript (using AS3, as I said in the title), and I'm trying to make a basic escape the room game. I haven't gotten far, and right now that's because every time I test my game (or publish preview it) the graphics get this annoying outline. Here it is when tested: http://i305.photobucket.com/albums/nn228/chokingondrama/flash.png
Every outline corresponds to some object present in the game, most of which have an alpha component of 0 since they're on different sides of the room. This didn't happen before, but once I added the code that allowed the player to change their view with the arrow (each viewpoint/wall is a different frame) these appeared.
It's a little different when published to HTML, basically it just gives each image a white background: http://i305.photobucket.com/albums/nn228/chokingondrama/html.png
Also, it would be nice if somebody could give me advice on how to make sure importing to flash won't result in lower quality.
Thanks in advance. If needed, I'll post any part of the code.
Some tips:
Don't set alpha to 0, instead use the visible property, setting movieclip.visible = false will make it a lot more efficient.
As for the importing and quality, after you import to stage or library, bring up the library (ctrl + l), and right click on the file you imported, go to properties. If it's an image, set compression to lossless, and allow smoothing.
For audio, go to file-> publish settings, and change audio stream and audio event (whichever you might use) to 128kbps.
As for your main question, I need more info, if you want you can post your source. It might be because of how you are placing your graphics on the stage.
For each of your MovieClips in question:
Try disabling button mode and see if the rectangles go away.
movieClipName.buttonMode = false;
If that doesn't help, or you really want button mode, try setting
movieClipName.tabEnabled = false;
There's a chance that since you added keyboard interaction each of your MovieClips are now expecting to be selected by the user when they press the tab key, much like any normal web form.
tabEnabled in the docs
You could also try
movieClipName.focusRect = false;

I'm trying to create an EXE projector using flash 5.5 AS3 where I have a few videos (FLVs) to show (their location is right next to the exe file in the same directory) - each load in a different frame, and all of those videos should also have a full screen option to them. Those are original videos that people WILL want to watch in full screen. It's essential for the experience...
The problem(s) I currently have (after fixing the sound that didn't stop after going to a different video) are hard to describe, but I'll try really hard.
Ok, so when I click the full screen button on a video and watch it in full screen, I will eventually want to exit the full screen, so I click on the same icon at the bottom to exit full screen (or ESC button, it's the same) and then click the navigation button to go to the SECOND FLV's frame to watch the other video. After watching the second video in full screen and then exiting full screen, flash takes me to the FIRST video's frame and that is a big problem. Also, now the button that takes me BACK to the second video's frame won't work. It's like flash is stuck.
I use the Components --> FLVPlayback 2.5 from the componant menu (I don't really know AS3 programming) and I fix its properties in the component parameters.
Also, I don't think that any of the followings are the reason for the bug, but I use these 3 scripts to stop all sound when navigating away from one frame (with an FLVplayback) to
another frame with another FLVplayback:
MyFLV.stop();
SoundMixer.stopAll();
MyFLV.addEventListener(Event.REMOVED_FROM_STAGE,xyz);
function xyz(e:Event):void{
MyFLV.stop();
}
I've found these online where people asked help for the sound bug I described.
The third script was suppose to remove the FLVplayback from the stage before going to another frame, but it works only when NOT GETTING INTO FULL SCREEN. I need something that will COMPLETELY remove the previous video from the stage so after exiting the SECOND viewed video, flash won't take me to a video that from some reason is still in its memory. I have something like 30 videos in my project and I need to remove each and every one of them off of the stage before navigating to the next frame to open a new FLVPlayback.
I tried to add a link to a demo I made with the problem so you can look at it, but it triggered a "oops, something went wrong" error, probably anti spam mechanism...
I would recommend using only one frame and only one flvplayback instance. Otherwise you have to deal with weird bugs like the one you are getting (usually caused by misplaced or forgotten code). Of course, using only one frame requires using more code, but with the number of hard-fixes it looks like you were making for the bugs, you may end up with less code.
Don't worry, I'll walk you through everything!
Reasons to use code (as opposed to multiple frames):
Easier to keep track of:
Know where all your code is so you can easily find and fix any problems.
Make changes more easily
You want to switch an existing video? edit a file reference and you are done.
Want to add a video? no more dragging a new flvplayback instance onto a new frame just add some very simple code and a button and you're done.
More customization
Reasons to use multiple frames (and multiple flvplayback instances):
easier to place visually
Some people find it easier when they have an actual movieclip that they can visually place on the stage
Less code
Here we go:
//import flv library
import fl.video.*;
This allows you to use ActionScript to manipulate the flv player
//video playback code-----------------------//
var myVideo:FLVPlayback = new FLVPlayback();
this creates an instance of FLVPlayback called myVideo (referenced from now on in the code as myVideo)
this next chunk shows many of the customizable features of the flv player. It is not necessary to include them.
//places the video player on stage at x,y
myVideo.x = 115;
myVideo.y = -10;
//uses SkinOverPlayFullscreen.swf for controls
myVideo.skin = "SkinOverPlayFullscreen.swf";
//color of controls
myVideo.skinBackgroundColor = 0x333333;
//hide controls and time it takes controls to fade and reappear (milliseconds)
myVideo.skinAutoHide=true;
myVideo.skinFadeTime=300;
//add the player to the stage
addChild(myVideo);
And now comes the important part. I have made buttons and added them to the stage. I gave each of the buttons a different instance name (box1_btn, box2_btn, and box3_btn). When someone clicks on a button, an "event" will occur.
//button listener code-------------------------//
//when button 1 is clicked throw button 1 event
box1_btn.addEventListener(MouseEvent.CLICK, clicked1);
//when button 2 is clicked throw button 2 event
box2_btn.addEventListener(MouseEvent.CLICK, clicked2);
//when button 3 is clicked throw button 3 event
box3_btn.addEventListener(MouseEvent.CLICK, clicked3);
//play different videos for different buttons---------//
//when button 1 event is thrown
function clicked1($e:MouseEvent):void
{
//play video 1.flv
myVideo.source = "1.flv";
}
//when button 2 event is thrown
function clicked2($e:MouseEvent):void
{
//play video 2.flv
myVideo.source = "2.flv";
}
//when button 3 event is thrown
function clicked3($e:MouseEvent):void
{
//play video 3.flv
myVideo.source = "3.flv";
}
This code will not have any sounds that keep playing because two videos cannot play at the same time in one instance of the player. Nor will it have any mess-ups when you come out of fullscreen because there is only one frame for the video to go back to.
Some possible problems you may run into:
It doesn't work at all:
Make sure you have added an instance of FLVPlayback to the library by adding an instance to the stage from the components menu (window>>components or ctrl+F7) and then deleting it from the stage (it should still appear in the library).
The playback buttons I want aren't showing up:
There is a great explanation of how to use As3 to manipulate FLVPlayback here:
http://www.republicofcode.com/tutorials/flash/as3flvplayback/
find the section about "Applying a Skin to the FLVPlayback Component" and follow it to use an adobe playback skin. If you want to make your own unique skin I would recommend opening and editing one of the pre-made skins. I found mine in
C:\Program Files (x86)\Adobe\Adobe Flash CS6\Common\Configuration\FLVPlayback Skins\FLA\ActionScript 3.0
I hope this helps!
Below would be simplest way to unload the FLVPlayback
removeChild(MyFLV);
it works fine for me
flvPlayBack.stop();
removeChild(flvPlayBack);
stops the sound and removes the playback.
Is it possible to get and set seek position of a swf file (either in ActionScript 2/3 or ActiveX API of Flash Player) ?
I tried to use frame number at first (to determine which part of the movie is being played) however sometimes whole animation has 2 frames and it does not help.
Any ideas?
Thanks.
if your loaded SWF contains all animation on the stage timeline ( i mean the top level ) then the progress you are seeking is:
var progress:Number = swf.currentFrame / swf.totalFrames;
if you want to set seek:
swf.gotoAndPlay ( progress * swf.totalFrames )
Also it can be that the all animation is not on the top level, but in the movieClip, which address you know, i mean stage.getChildByName ( 'something ).getChildeByName ('something )...
but if you have an swf where are multiple movieclips, and they are playing independantly, then nothing i can help....
Not without coding something in to the SWF as far as I know. Because animations in Flash can be in embedded MovieClips, or entirely scripted in a single frame, there is no easy way to detect the total playing time or how far an animation has progressed. Any get/seek functionality, or even a progress broadcast, would have to be scripted in the SWF and accessed through ExternalInterface.
Please be more specific about your problem. If your swf file is only 2 frames, then what is it that you are trying to seek through? Does your swf load a video, for example, and this is what you are trying to seek through? (In which case you can get properties of a video object's playback position and state).
Without more information, it's hard to provide a clear answer.
