在 Android 中抓取框架视频到 Gif
原标题:Grab Frame VideoToGif in Android

我试图从机器人的视频文件中抓取框架, 唯一的替代方案( 已经编译完毕可供使用) 是 < a href=" http://code.google.com/ p/viewtogif/" rel="nofollow" >victalToGif < /a> Project. 它在Android内部使用 JavaCV、 JavaCpp 和 Java SE! 最后的 Apk 是非常大的, 但我正在做一个学术项目...

ERROR I m using the follow code:

ModifiedFrameGrabber frameGrabber = new ModifiedFrameGrabber(VIDEO_PATH);
IplImage frame = null;

try
{
    frameGrabber.start();
    frame = frameGrabber.grab();
} catch(Exception e){...}

byte[] data = frame.getByteBuffer().array();

在最后一行,我得到错误:

Caused by: java.lang.UnsupportedOperationException
    at java.nio.DirectByteBuffer.protectedArray(DirectByteBuffer.java:292)
    at java.nio.ByteBuffer.array(ByteBuffer.java:144)
    at my.package.onCreate(MyClass:x)

有人能帮我吗?

最佳回答

直接 NIO 缓冲区没有数组。 调用 < code> get () 而不是 < code> array () ()
