Since the decoding capability of the hardware decoder is usually fixed, the satisfaction of the load balancing condition is usually caused by the change of the soft decoding situation.

  • the soft decoding is that the soft decoding capability is insufficient, it means that the CPU cannot complete the decoding of all the first data on time according to the pre-plan.

During the decoding process, it was found that the CPU provided more computing resources than expected for soft decoding, and its soft decoding capacity was excessive. In this case, since the hardware decoder decodes the second data in head-to-tail order, the unprocessed second unprocessed part can be selected from the tail of the original 9M, and the 1M size can be divided as the third part data, and determine the remaining second unprocessed part as fourth data.
