Public Attributes

uint8_t skip_frame_flag
 Indicates skip frames as below. 0: Encode as normal, no skip. 1: One or more frames were skipped prior to the current frame, encode the current frame as normal. 2: The current frame is to be skipped, do not encode it but pack/encrypt the packed header contents (all except VAEncPackedHeaderSlice) which could contain actual frame contents (e.g. pack the frame in VAEncPackedHeaderPicture).
uint8_t num_skip_frames
 The number of frames skipped prior to the current frame. Valid when skip_frame_flag = 1.
uint32_t size_skip_frames
 When skip_frame_flag = 1, the size of the skipped frames in bits. When skip_frame_flag = 2, the size of the current skipped frame that is to be packed/encrypted in bits.
uint32_t va_reserved [VA_PADDING_LOW]
 Reserved bytes for future use, must be zero.

Detailed Description

Encoding skip frame.

The application may choose to skip frames externally to the encoder (e.g. drop completely or code as all skip's). For rate control purposes the encoder will need to know the size and number of skipped frames. Skip frame(s) indicated through this structure is applicable only to the current frame. It is allowed for the application to still send in packed headers for the driver to pack, although no frame will be encoded (e.g. for HW to encrypt the frame).

The documentation for this struct was generated from the following file:
