Detailed Description

Typedef Documentation

typedef void(* vpx_decrypt_cb)(void *decrypt_state, const unsigned char *input, unsigned char *output, int count)

Decrypt n bytes of data from input -> output, using the decrypt_state passed in VPXD_SET_DECRYPTOR.

typedef struct vpx_decrypt_init vpx_decrypt_init

Structure to hold decryption state.

Defines a structure to hold the decryption state and access function.

Enumeration Type Documentation

enum vp8_dec_control_id

VP8 decoder control functions.

This set of macros define the control functions available for the VP8 decoder interface.

Enumerator
VP8D_GET_LAST_REF_UPDATES	control function to get info on which reference frames were updated by the last decode
VP8D_GET_FRAME_CORRUPTED	check if the indicated frame is corrupted
VP8D_GET_LAST_REF_USED	control function to get info on which reference frames were used by the last decode
VPXD_SET_DECRYPTOR	decryption function to decrypt encoded buffer data immediately before decoding. Takes a vpx_decrypt_init, which contains a callback function and opaque context pointer.
VP9D_GET_DISPLAY_SIZE	control function to get the display dimensions for the current frame.
VP9_INVERT_TILE_DECODE_ORDER	For testing.
