修改jpegimagestomovie文件

因此,在接收到用于创建视频文件的Java包的一些建议之后,我决定尝试修改JPEGIGESTEMOVIVE文件,它是JMF的一个示例。我成功地编译了所有的东西,似乎它应该运行。新的类应该采用bufferedImages的向量,然后我直接从bufferedImage转换为字节数组,而不是像以前那样从文件读取并转换为字节数组。问题在于处理器不会进行配置(它会锁定或类似的配置)。有人能看到导致这种情况的任何明显缺陷吗?

另外,我仍然完全愿意接受关于更好/更容易/更简单框架的建议。

编辑:这是一些我实际做了一些事情的代码。为了可读性,这里清理了一点。

class ImageDataSource extends PullBufferDataSource {

ImageSourceStream streams[];

ImageDataSource(int width, int height, int frameRate, Vector images) {
    streams = new ImageSourceStream[1];
    streams[0] = new ImageSourceStream(width, height, frameRate, images);
}

/**
 * The source stream to go along with ImageDataSource.
 */
class ImageSourceStream implements PullBufferStream {

Vector images;
int width, height;
VideoFormat format;

int nextImage = 0;  // index of the next image to be read.
boolean ended = false;

public ImageSourceStream(int width, int height, int frameRate, Vector images) {
    this.width = width;
    this.height = height;
    this.images = images;

    format = new VideoFormat(null,
            new Dimension(width, height),
            Format.NOT_SPECIFIED,
            Format.byteArray,
            (float)frameRate);
}

/**
 * This is called from the Processor to read a frame worth
 * of video data.
 */
public void read(Buffer buf) throws IOException {

    // Check if we've finished all the frames.
    if (nextImage >= images.size()) {
    // We are done.  Set EndOfMedia.
    System.err.println("Done reading all images.");
    buf.setEOM(true);
    buf.setOffset(0);
    buf.setLength(0);
    ended = true;
    return;
    }

    BufferedImage imageFile = (BufferedImage)images.elementAt(nextImage);
    nextImage++;


    byte data[] = ImageToByteArray.convertToBytes(imageFile);
    // Check the input buffer type & size.

    if (buf.getData() instanceof byte[])
    data = (byte[])buf.getData();

    // Check to see the given buffer is big enough for the frame.

    buf.setData(data);

    buf.setOffset(0);
    buf.setLength((int)data.length);
    buf.setFormat(format);
    buf.setFlags(buf.getFlags() | buf.FLAG_KEY_FRAME);
}

有一件事我不确定,那就是用什么作为视频格式的编码。
