大华摄像头遇到的问题

[bulreed]

大华摄像头播放时遇到如下异常: 平台RK3288，Android版本4.4.4
java.lang.IllegalStateException
E/AndroidRuntime( 1926): at android.media.MediaCodec.getOutputFormatNative(Native Method)
E/AndroidRuntime( 1926): at android.media.MediaCodec.getOutputFormat(MediaCodec.java:533)
E/AndroidRuntime( 1926): at cn.cloudwalk.camera.VideoDecoder.init(VideoDecoder.java:157)
E/AndroidRuntime( 1926): at cn.cloudwalk.camera.DecodeStream.notifyOpened(DecodeStream.java:187)
E/AndroidRuntime( 1926): at cn.cloudwalk.camera.SCCallback.SCMessageHandler(SCCallback.java:23)
E/AndroidRuntime( 1926): at dalvik.system.NativeStart.run(Native Method)

代码对应format = mMediaCodec.getOutputFormat().getInteger(MediaFormat.KEY_COLOR_FORMAT);

如果注释掉上述代码，就会出现下面的Underflow异常
java.nio.BufferUnderflowException
