Java如何通过编程将图像编码成视频文件?

[英]How to encode images into a video file in Java through programming?

I am trying to encode some images of same resolution into a video file using, For that I have tried:我正在尝试使用将一些相同分辨率的图像编码到视频文件中,为此我尝试过:

jCodec编解码器

  • jcodec ..example description jcodec .. 示例说明

    But it is very time consuming and not a proper tool to encode large number of images and it creates a quick time extension.但是它非常耗时,并且不是编码大量图像的合适工具,并且会产生快速的时间扩展。

FFMPEG FFMPEG

  • FFMPEG ..example description FFMPEG ..示例说明

    But ffmpeg only able to create video from image files.但是 ffmpeg 只能从图像文件创建视频。 Images need to be create on physical system.图像需要在物理系统上创建。

I have heard Xuggler that its APIs can be used in java program to create video file but as its site seems broken.我听说Xuggler可以在 Java 程序中使用它的 API 来创建视频文件,但它的网站似乎已损坏。 I am unable to try it.我无法尝试。

Does anybody know how to encode images in java format into a video file Please help!有谁知道如何将java格式的图像编码成视频文件请帮忙!

THanks in Advance !提前致谢!

Xuggler is deprecated , use Humble-Video instead. Xuggler弃用,请改用Humble-Video It already comes with some demo projects, including how to take screenshots and convert it to a video file: RecordAndEncodeVideo.java它已经附带了一些演示项目,包括如何截取屏幕截图并将其转换为视频文件: RecordAndEncodeVideo.java

I am using it for real time using on a webapp.我在 webapp 上实时使用它。

If you will gonna stream this in real time you will need a RTSP server.如果您要实时流式传输此内容,您将需要一个RTSP服务器。 You can either use big frameworks like Red 5 Server , Wowza Streaming Engine or you can built your own server using Netty which has a built in RTSP codec since version 3.2.您可以使用Red 5 ServerWowza Streaming Engine等大型框架,也可以使用Netty构建自己的服务器, Netty自 3.2 版起就内置了 RTSP 编解码器。

Using command line, there are various ways to convert image to video.使用命令行,有多种方法可以将图像转换为视频。 You can use those command in java for saving.您可以在 java 中使用这些命令进行保存。 You can get those commands from the following link:您可以从以下链接获取这些命令:

  1. Using ffmpeg to convert a set of images into a video 使用 ffmpeg 将一组图像转换为视频
  2. Create a video slideshow from images 从图像创建视频幻灯片

Another approach for Android developers: Android 开发人员的另一种方法:

  1. Create a temporary folder inside the Android.在 Android 内部创建一个临时文件夹。
  2. Copy your images in the new folder将图像复制到新文件夹中
  3. First, rename your pictures to follow a numerical sequence.首先,重命名图片以遵循数字顺序。 For example, img1.jpg, img2.jpg, img3.jpg,... Then you may run:比如img1.jpg, img2.jpg, img3.jpg,... 那么你可以运行:
  4. Run this program programmetcally ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg To run this programmatically,以编程方式运行此程序 ffm​​peg -f image2 -i img%d.jpg /tmp/a.mpg 以编程方式运行此程序,

Use the following code:使用以下代码:

void convertImg_to_vid()
{
    Process chperm;
    try {
        chperm=Runtime.getRuntime().exec("su");
          DataOutputStream os = 
              new DataOutputStream(chperm.getOutputStream());

              os.writeBytes("ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg\n");
              os.flush();

              chperm.waitFor();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
