* Mpp Metadata definition
|
|
*
|
|
* Metadata is for information transmision in mpp.
|
|
* Mpp task will contain two meta data:
|
|
*
|
|
* 1. Data flow metadata
|
|
* This metadata contains information of input / output data flow. For example
|
|
* A. decoder input side task the input packet must be defined and output frame
|
|
* may not be defined. Then decoder will try malloc or use committed buffer to
|
|
* complete decoding.
|
|
* B. decoder output side task
|
|
*
|
|
*
|
|
* 2. Flow control metadata
