* kMetadataBufferTypeGraphicBuffer is used to indicate that
* the payload of the metadata buffers can be interpreted as
* a GraphicBuffer. It is only to be used by software encoders.
* In this case, the metadata that the encoder receives
* will have a byte stream that consists of two parts:
* 1. First, there is an integer indicating that the metadata
* contains a GraphicBuffer (kMetadataBufferTypeGraphicBuffer)
* 2. This is followed by the pointer to the GraphicBuffer that
* is to be encoded. Encoder must not create a sp<> from this
* graphic buffer, or free it, as it does not actually own this
* buffer.
