METADATA ASSISTED VIDEO DECODING

摘要

A video decoder is disclosed that uses metadata in order to make optimization decisions. In one embodiment, metadata is used to choose which of multiple available decoder engines should receive a video sequence. In another embodiment, the optimization decisions can be based on length and location metadata information associated with a video sequence. Using such metadata information, a decoder engine can skip start-code scanning to make the decoding process more efficient. Also based on the choice of decoder engine, it can decide whether emulation prevention byte removal shall happen together with start code scanning or not.

主权项

1. In a computing device that implements a video decoder, a method comprising:
receiving an encoded video sequence with a file container; with the computing device that implements the video decoder, analyzing metadata associated with the encoded video sequence in the file container; and using the metadata to make decoder optimization decisions in the video decoder.
