jni中char[]如何转成ByteBuffer

[waydeom]

在jni中，给out赋值之后，如何把Out里的内容再拷贝到pOutBuffer中，我现在的方法返回到java中pOutBuffer是空的。

jmethodID ArrayMethodId = env->GetMethodID(ByteBufferClass,"array","()[B");
jmethodID ClearMethodId = env->GetMethodID(ByteBufferClass,"clear","()Ljava/nio/Buffer;");

// clear output buffer
env->CallObjectMethod(pOutBuffer,ClearMethodId);
OutByteArray = (jbyteArray)env->CallObjectMethod(pOutBuffer, ArrayMethodId);
OutJbyte = env->GetByteArrayElements(OutByteArray,0);
Out = (unsigned char *)OutJbyte;

DecodeSize = AVDecode(m_pVideoDecode, (unsigned char *)In, inputSize, (unsigned char **)&Out, (int *)&pBFrameKey);

//把Out设置到pOutBuffer？？？？？？？？？？？？？
