OH_AVCodecCallback

typedef struct OH_AVCodecCallback {...} OH_AVCodecCallback

Overview

The struct defines all the asynchronous callback function pointers of an OH_AVCodec instance. To ensure the normal running of OH_AVCodec, you must register the instance of this struct with the OH_AVCodec instance and process the information reported by the callback function.
