  • What video format works both on Windows and all Apple products out-of-the-box?

    - by Seppo Silaste
    What format and encoding should I use for video that would play out-of-the-box on both Windows and all Apple products (iPad, iPhone, etc.)? I know that the correct way to render an animation, is to first render it as images, but this is overkill when rendering short animations of a work in progress for the client to comment on. I have one client that views the vids on Windows and another that views them on iPad and iPhone. I'm hoping I could render just one video instead of rendering in two different formats.

  • Android Frame based animation memory problem

    - by madsleejensen
    Hi all Im trying to create a animation on top of a Camera Surface view. The animation if a box rotating, and to enable transparency i made a bunch of *.png files that i want to just switch out on top of the Camera view. The problem is Android wont allow me to allocate so many images (too much memory required) so the AnimationDrawable is not an option. Will i be able to allocate all the *.png bitmaps if i use OpenGL instead? then i would store all the *.png's as Textures and just make my own animation logic? is am i under the same restrictions there? Any ideas on how to solve this problem ? Ive made a Custom view that loads the image resource on every frame and discards it when next frame is to be displayed. But the performance is terrible. import android.app.Activity; import android.content.res.Resources; import android.graphics.drawable.Drawable; import android.os.SystemClock; import android.util.Log; import android.widget.ImageView; public class FrameAnimationView extends ImageView { private int mFramesPerSecond = 10; private int mTimeBetweenFrames = (1000 / mFramesPerSecond); private int mCurrentFrame = 1; private String[] mFrames; private Thread mAnimationThread; private Resources mResources; private String mIdentifierPrefix; private Activity mContext; private boolean mIsAnimating = false; private Integer[] mDrawableIndentifiers; public FrameAnimationView(Activity context, String[] frames) { super(context); mContext = context; mResources = context.getResources(); mFrames = frames; mIdentifierPrefix = context.getPackageName() + ":drawable/"; mDrawableIndentifiers = new Integer[frames.length]; } private void initAnimationThread() { mAnimationThread = new Thread(new Runnable() { @Override public void run() { while (mIsAnimating) { final int frameToShow = (mCurrentFrame - 1); //Log.e("frame", Integer.toString(frameToShow)); mContext.runOnUiThread(new Runnable() { @Override public void run() { if (mDrawableIndentifiers[frameToShow] == null) { String frameId = mFrames[frameToShow]; int drawableResourceId = mResources.getIdentifier(mIdentifierPrefix + frameId, null, null); mDrawableIndentifiers[frameToShow] = drawableResourceId; } Drawable frame = getResources().getDrawable(mDrawableIndentifiers[frameToShow]); setBackgroundDrawable(frame); if (mCurrentFrame < mFrames.length) { mCurrentFrame++; } else { mCurrentFrame = 1; } } }); try { Thread.sleep(mTimeBetweenFrames); } catch (InterruptedException e) { e.printStackTrace(); } } } }); } public void setFramesPerSecond(int fps) { mFramesPerSecond = fps; mTimeBetweenFrames = (1000 / mFramesPerSecond); } public void startAnimation() { if (mIsAnimating) return; mIsAnimating = true; initAnimationThread(); mAnimationThread.start(); } public void stopAnimation() { if (mIsAnimating) { Thread oldThread = mAnimationThread; mAnimationThread = null; oldThread.interrupt(); mIsAnimating = false; } } }

  • OpenGl glutIdleFunc(void (*func)(void))

    - by PHENOMERICAN
    I'm trying to design very simple animation in OpenGL such as rotating and translating objects. In the red book, I found that using GLUT's glutIdleFunc() is okay for a simple animation. How many times does glutIdleFunc(...) call the function in one second? Thank you.

  • UIDisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by UIDisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • What is this effect called? 'Grow/shrink'? 'Fly-out/fly-in'? ...

    - by Majid
    Hi all, I have seen links that open modal windows AND have a nice animation effect that create the illusion that the window grows out of the link clicked. On closing the window a similar animation shows that the window shrinks and disappears in the link which originally opened it. I remember I saw it on some jquery page but don't remember where and don't know what this effect is called. Have you seen this? Examples?

  • Disable animations when ending search in iPhone

    - by camilo
    Hi. A quicky: is there a way to dismiss the keyboard and the searchDisplayController without animation? I was able to do it when the user presses "Cancel", but when the user presses the black "window thingy" above search field (only visible while the user hasn't inserted any text), the animation always occurs, even when I change the delegate functions. Is there a way to control this, or as an alternative, to disable the user to end searching by pressing the black window? Thanks in advance.

  • Android: Screen goes black behind interstitial ad while it slides in

    - by Scienceprodigy
    I show interstitial ads in my app, and I have defined a translation animation that is set to slide the ad in from right to left. The ad slides in just fine, but when the animation starts, the underlying Activity becomes completely black while the ad slides in. I would like to be able to see the underlying Activity and have the ad slide in over it. How do I keep the underlying Activity from being covered with black?

  • jQuery slideToggle() Internet Explorer problem and jumpy animation

    - by UtothaX
    Hey yaa! I have a big problem with my jquery. I finally made it that my slidetoggle runs in firefox. The animation is a little bit jumpy in the end of the animation. I read a lot of workarounds, but somehow nothing helped me really. Perhaps anyone of you can rescue me out of this dilemma. The other bigger problem is that the hidden divs are unfortunately shown directly on start in internet explorer. I tested it in IE6&7. And the sliding effect is also very strange. Does anyone of you know if I have to give additional styling for IE??? Here is my site I am working on: http://www.haus-plan.de/%5F01%5FHausplan/ the red titles are slideable in the content area and the two Slide words on the right panel. I noticed that Internet Explorer runs the first Slide word on the right panel correctly. Here its div is first hidden and only shows up when we click and let it slide down. But for the other divs they are shown in the beginning which is very sh..... Please help meee....

  • Loading animation Memory leak

    - by Ayaz Alavi
    Hi, I have written network class that is managing all network calls for my application. There are two methods showLoadingAnimationView and hideLoadingAnimationView that will show UIActivityIndicatorView in a view over my current viewcontroller with fade background. I am getting memory leaks somewhere on these two methods. Here is the code -(void)showLoadingAnimationView { textmeAppDelegate *textme = (textmeAppDelegate *)[[UIApplication sharedApplication] delegate]; [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; if(wrapperLoading != nil) { [wrapperLoading release]; } wrapperLoading = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; wrapperLoading.backgroundColor = [UIColor clearColor]; wrapperLoading.alpha = 0.8; UIView *_loadingBG = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; _loadingBG.backgroundColor = [UIColor blackColor]; _loadingBG.alpha = 0.4; circlingWheel = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; CGRect wheelFrame = circlingWheel.frame; circlingWheel.frame = CGRectMake(((320.0 - wheelFrame.size.width) / 2.0), ((480.0 - wheelFrame.size.height) / 2.0), wheelFrame.size.width, wheelFrame.size.height); [wrapperLoading addSubview:_loadingBG]; [wrapperLoading addSubview:circlingWheel]; [circlingWheel startAnimating]; [textme.window addSubview:wrapperLoading]; [_loadingBG release]; [circlingWheel release]; } -(void)hideLoadingAnimationView { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; wrapperLoading.alpha = 0.0; [self.wrapperLoading removeFromSuperview]; //[NSTimer scheduledTimerWithTimeInterval:0.8 target:wrapperLoading selector:@selector(removeFromSuperview) userInfo:nil repeats:NO]; } Here is how I am calling these two methods [NSThread detachNewThreadSelector:@selector(showLoadingAnimationView) toTarget:self withObject:nil]; and then somewhere later in the code i am using following function call to hide animation. [self hideLoadingAnimationView]; I am getting memory leaks when I call showLoadingAnimationView function. Anything wrong in the code or is there any better technique to show loading animation when we do network calls?

  • jQuery Accordion: IE animation issues

    - by Nathan Long
    Update I am making this a community wiki, for three reasons: I don't feel like I got a definitive answer, but I have long since stopped needing an answer, because I rolled my own accordion function this question gets tons of views, so clearly lots of people are still interested So if anybody wants to change/clarify this question and make it a definitive guide, be my guest. I'm working on a page using jQuery's accordion UI element. I modeled my HTML on that example, except that inside the <li> elements, I have some unordered lists of links. Like this: $(document).ready(function() { $(".ui-accordion-container").accordion( {active: "a.default", alwaysOpen: true, autoHeight: false} ); }); <ul class="ui-accordion-container"> <li> <!-- Start accordion section --> <a href='#' class="accordion-label">A Group of Links</a> <ul class="linklist"> <li><a href="http://example.com">Example Link</a></li> <li><a href="http://example.com">Example Link</a></li> </ul> <!--and of course there's another group --> Problem: IE Animation stinks Although IE7 animates the documentation's example accordion menu just fine, it has problems with mine. Specifically, one accordion menu on the page moves jerkily and has flashes of content. I know that it's not a CSS issue because the same thing happens if I don't include my CSS files. The other accordion menu on the page opens the first section you click and, after that, won't open any of them. Both of these problems are IE-specific, and both go away if I use the option animated: false. But I'd like to keep the default slide animation, since it helps the user understand what the menu is doing. Is there another way?

  • How to play animation in order in ipad

    - by juliet
    I have two animations for two layers, layer1 and layer2, each has different path. So, I want to know how can play them in order. first play layer1's animation, and then layer2. here is my two animation code! layer1 CALayer *layer1 = [CALayer layer]; [self.layer addSublayer:layer1]; CAKeyframeAnimation *animation1 = [CAKeyframeAnimation animationWithKeyPath:@"position"]; layer1.contents = (id)image1.CGImage; layer1.anchorPoint = CGPointZero; layer1.frame = CGRectMake(0.0f, 0.0f, image1.size.width, image1.size.height); animation1.path = path1; animation1.duration = 2.0f; animation1.calculationMode = kCAAnimationLinear; [layer1 addAnimation:animation1 forKey:@"position"]; layer2 CALayer *layer2 = [CALayer layer]; [self.layer addSublayer:layer2]; CAKeyframeAnimation *animation2 = [CAKeyframeAnimation animationWithKeyPath:@"position"]; layer2.contents = (id)image2.CGImage; layer2.anchorPoint = CGPointZero; layer2.frame = CGRectMake(0.0f, 0.0f, image2.size.width, image2.size.height); animation2.path = path2; animation2.duration = 2.0f; animation2.calculationMode = kCAAnimationLinear; [layer2 addAnimation:animation2 forKey:@"position"];

  • State Animation on ListBox ItemTemplate

    - by Peanut
    I have a listbox which reads from Observable collection, and is ItemTemplate'ed: <DataTemplate x:Key="DataTemplate1"> <Grid x:Name="grid" Height="47.333" Width="577" Opacity="0.495"> <Image HorizontalAlignment="Left" Margin="10.668,8,0,8" Width="34" Source="{Binding ImageLocation}"/> <TextBlock Margin="56,8,172.334,8" TextWrapping="Wrap" Text="{Binding ApplicationName}" FontSize="21.333"/> <Grid x:Name="grid1" HorizontalAlignment="Right" Margin="0,10.003,-0.009,11.33" Width="26" Opacity="0" RenderTransformOrigin="0.5,0.5"> <Image HorizontalAlignment="Stretch" Margin="0" Source="image/downloads.png" Stretch="Fill" MouseDown="Image_MouseDown" /> </Grid> </Grid> </DataTemplate> <ListBox x:Name="searchlist" Margin="8" ItemTemplate="{DynamicResource DataTemplate1}" ItemsSource="{Binding SearchResults}" SelectionChanged="searchlist_SelectionChanged" ItemContainerStyle="{DynamicResource ListBoxItemStyle1}" /> In general, my question is "What is the easiest way to do Animation on Particular Items in this listbox As they are selected? Basically the image inside the "grid1" will be setting its opacity to 1, slowly. I would prefer to use states, but I do not know of any way to just tell blend and xaml to "When a selected item is changed, change the image opacity to 1 over a period of .3 seconds". Infact, I have been doing this in the .cs file using the VisualStateManager. Also, there is another issue. When the selected index is changed, we goto the CS file and look at SelectedItem. SelectedItem returns an instance of the Object in which it was bound to (The object inside the observable collection), and NOT an instance of the DataTemplate/ListItem etc. So how am I able to pull the correct image out of this list? State animation with VisualStateManager I can handle fine if its just normal things, but when it comes to generated listboxes' items, I'm lost. Thanks

  • ipad full screen (1024x768) animation with around 1800 frames fps problem

    - by Muhammad Farhan
    Hi there. what i am trying to do is to play a full screen(1024x768) animation on ipad with an fps of around 20. i have got a scene with 1800 full screen frames. till now i have tried a lot of approaches but have encountered a lot of problems. my first approach was to get the texture using the following function t = [[CCTexture2D alloc] initWithImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"(%d)",startIndex] ofType:type]]]; give it to sprite by using setTexture method and then release the texture then create a new texture with next frame and repeat the procedure but by using this approach i only get an FPS of about 7. my second approach was to preload about 10 textures in texturecache save them in an array and give them to sprite using setTexture and on the back end i am replacing the old textures with the new texture in a thread but the problem i face is that creating new texture and adding to array takes some time and when the settexture method is called the sprite displays the old texture because the new one is not loaded yet but after some time new texture get loaded. Is there any way i can run a full screen animation on ipad at around 20 fps plesae help me out. Thanks Farhan

  • determining the starting speed for an accelerated animation (in flash/actionscript but it's a math question)

    - by vulkanino
    This question burns my brain. I have an object on a plane, but for the sake of simplicity let's work just on a single dimension, thus the object has a starting position xs. I know the ending position xe. The object has to move from starting to ending position with an accelerated (acceleration=a) movement. I know the velocity the object has to have at the ending position (=ve). In my special case the ending speed is zero, but of course I need a general formula. The only unknown is the starting velocity vs. The objects starts with vs in xs and ends with ve in xe, moving along a space x with an acceleration a in a time t. Since I'm working with flash, space is expressed in pixels, time is expressed in frames (but you can reason in terms of seconds, it's easy to convert knowing the frames-per-second). In the animation loop (think onEnterFrame) I compute the new velocity and the new position with (a=0.4 for example): vx *= a (same for vy) x += vx (same for y) I want the entire animation to last, say, 2 seconds, which at 30 fps is 60 frames. Now you know that in 60 frames my object has to move from xs to xe with a constant deceleration so that the ending speed is 0. How do I compute the starting speed vs? Maybe there's a simpler way to do this in Flash, but I am now interested in the math/physics behind this.

  • Video/Animated GIF advanced frame editor?

    - by meder
    What sort of application could I use for example if I had a 5 minute video or an animated GIF with 50 frames, and I wanted to basically Photoshop replace an object, say a person's head, with another image for all those 50 frames? Is there some sort of smart tool that can do this or do I have to edit every single frame by hand? I wouldn't mind there being a tool where I can paste the image in every frame automatically, and switch from frame to frame adjusting the position of it, I just need something efficient. I've tried using Photoshop's import video into image sequence and tried editing with the animation toolbar at the bottom, but it's not quite what I want. I don't care if it's free software or not, I'm primarily using Linux but I have VirtualBox Windows XP if there's an excellent application that's not available otherwise.
