How to Properly Retrieve Information from MPP

To minimize CPU usage, the application layer should invoke MPI only when necessary. Avoid redundant MPI calls by caching retrieved information locally.

For instance, information retrieved from MPI_ENC_getVencAttr can be stored in a local variable and reused when needed.

MPI_ENC_getVencAttr should only be reinvoked to obtain updated information upon notification that the encoder configuration has changed.
