|

|

|

|
|
*
|
||
|
|
* (1.1) simple data api set:
|
||
|
|
*
|
||
|
|
* decode : both send video stream packet to decoder and get video frame from
|
||
|
|
* decoder at the same time.
|
||
|
|
*
|
||
|
|
* encode : both send video frame to encoder and get encoded video stream from
|
||
|
|
* encoder at the same time.
|
||
|
|
*
|
||
|
|
* decode_put_packet: send video stream packet to decoder only, async interface
|
||
|
|
*
|

|
* decode_get_frame : get video frame from decoder only, async interface

* encode_get_packet: get encoded video packet from encoder only, async interface

|
|
*
|
||
|
|
* (1.2) advanced task api set:
|
||
|
|
*
|
||
|
|
* poll : poll port for dequeue
|
||
|
|
*
|
||
|
|
* dequeue : pop a task from mpp task queue
|
||
|
|
*
|
||
|
|
* enqueue : push a task to mpp task queue
|
||
|
|
*
|
||
|
|
* (2). the control api set is for mpp context control including:
|
||
|
|
*
|
||
|
|
* control : similiar to ioctl in kernel driver, setup or get mpp internal parameter
|
||
|
|
*
|
||
|
|
* reset : clear all data in mpp context, discard all packet and frame,
|
||
|
|
* reset all components to initialized status
