You tube - player has additional two buttons on it. => Add to favorites on the left side. => Email this video on right side. I want to implement the same for my application.

问题 Whenever I change the frame of my AVPlayerLayer, the video is not resized immediately, but animated to the new size. For example: I change the frame from (0, 0, 100, 100) to (0, 0, 400, 400), the view's frame is changed immediately, but the video's size is animated to the new size. Has anyone encountered this issue? And if yes does someone know a way to disable the default animation? Thanks! 回答1: You can try disabling implicit actions and using zero length animations: CALayer *videolayer = <#

问题 I'm trying to look for an example of code that allows the user to animate a gif on mouseover and pause when mouse out. I've seen many tutorials talking about this but I want a different effect. I noticed that most gifs "reset" when on mouse out. That is, either the gif is covered with a generic image or the animation reverts back to the start. What I would like to achieve is a more seamless "pause" that allows you to start where you left off without using a placeholder image. Similar to the

问题 How would I set cookies such that a video only plays automatically on the first visit only, afterwards if they want to watch it, it must be played manually? 回答1: The general idea would be: on page load retrieve cookie information if no cookie, or its set to false, play the movie set cookie to true 回答2: Here's what I used on a project: if (document.cookie.length == 0 || document.cookie.indexOf("MYCOOKIENAME=") == -1) { // I set the path to / so once they'd seen it once on the site they wouldn

问题 I want to open an existing Movie-File and export every frame of this file to an image like JPEG or TIFF. I got so far until now: int main(int argc, char* argv[]) { char filename[255]; // Filename to ping. OSErr e; // Error return. FSSpec filespec; // QT file specification short filemovie; // QT movie handle. Movie movie; // QT movie "object".

问题 I have an app that's worked since version 2.0 of the SDK where I create and add a UIWebView and then load the URL of an .mov to play a movie. Ever since the early version of the 4.0 beta up until the 4.0 GM this has stopped working. When I load a movie now I get the following error: :Plug-in handled load" and the movie never displays. Is this a known issue? Am I doing something wrong in 4.0? 回答1: I figured this out. It appears to be an issue with iOS4 not being backward compatible with a

问题 I have a small UIView that displays a repeated movie. When the user taps a button another movie is loaded and displayed in the same UIView. The problem is that there is a half second "flash" between the removing of the first movie and the displaying of the second. Is there any to remove this? - (void) setUpMovie:(NSString*)title { NSString *url = [[NSBundle mainBundle] pathForResource:title ofType:@"mp4"]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:

问题 I am currently working with a RPi 3B (latest Raspbian Jessie) on a little project which involves playing a short .mp4 file. As Pygame seemed to support playing .mpg files, so I converted my video into that format. When I tried to import the movie module however, I get the common python import error: Traceback (most recent call last): File "film_app.py", line 3, in <module> import pygame.movie ImportError: No module named movie After some research, I figured others had the same issue as

问题 I basically have an matrix of bytes. Each row (meaning byte[]) represents an image. How do I create a movie out of that (any format - avi, mpeg, whatever), and save it as a file? Each image can be one of the following: int JPEG Encoded formats. int NV16 YCbCr format, used for video. int NV21 YCrCb format used for images, which uses the NV21 encoding format. int RGB_565 RGB format used for pictures encoded as RGB_565. int YUY2 YCbCr format used for images, which uses YUYV (YUY2) encoding
