* 1. length is runtime updated for each stage.

|
*
|
* 2. When writing vps/sps/pps encoder should update length.
|
* Then length will be kept before next stage is done.
|
* For example when vps/sps/pps were inserted and slice data need
|
* reencoding the hal should update length at the final loop.
|
*
|
* 3. length in task and length in packet should be updated at the same
|
* time. Encoder flow need to check these two length between stages.
