从图像和音频创建视频文件(预录制)
我遇到了一些示例代码,其中添加了一组图片来创建一个QTmovie。
I have come across some sample codes where set of images are added to make a QTmovie.
我针对这个OS X平台没有任何QT框架。
我想要创建一个带有扩展名的文件,并嵌入适当的元数据,并找到一种方法来插入所需格式的图像和音频。因此,当文件被创建时,它可以简单地播放。
I am targeting this for OS X platform without any QT frameworks. I have ague idea of creating a file with extension and embed it with appropriate metadata and find a way to insert images and audio in required format. So when the file is created it can simply be played.
我不知道什么格式/扩展更好。
指针非常感谢。
I am not sure of what format/extension is better. pointers are much appreciated.
如果你想编写一个程序来做这个,你可以使用 Xuggler 在Java中做到。
If you want to write a program to do this, you could use Xuggler in Java to do it. It will allow you to save your final video in a format playable by almost any media player.
通过了解视频文件(例如MP4,Quicktime)的开始方式,实际上代表了此过于简单化的音频和视频互联网视频指南。
Start out by gaining an understanding of how video files (e.g. MP4, Quicktime) actually represent audio and video with this Overly Simplistic Guide to Internet Video.
然后,使用 MediaTool教程。您可以编写将原始图片转换为视频文件的程序(请参阅此示例代码)。最后,要编写一个使音频和视频同步的程序,请参阅本教程;它会产生一组图像,并产生一些音频噪音,当一个球撞击一个盒子的边缘时,时间会改变。
Then, play around with the MediaTool tutorials. You can write programs that make raw images into video files (see this sample code). Finally, to write a program that makes audio and video that are in sync, see this tutorial; it generates a set of images, and makes some audio noise that is timed to change when a ball hits the edge of a box.
希望有帮助。
