WebM VP8 Codec SDK: WebM VP8 Encoder

#define VP8_EFLAG_NO_REF_LAST (1<<16)

Don't reference the last frame.

When this flag is set, the encoder will not use the last frame as a predictor. When not set, the encoder will choose whether to use the last frame or not automatically.

#define VP8_EFLAG_NO_REF_GF (1<<17)

Don't reference the golden frame.

When this flag is set, the encoder will not use the golden frame as a predictor. When not set, the encoder will choose whether to use the golden frame or not automatically.

#define VP8_EFLAG_NO_REF_ARF (1<<21)

Don't reference the alternate reference frame.

When this flag is set, the encoder will not use the alt ref frame as a predictor. When not set, the encoder will choose whether to use the alt ref frame or not automatically.

#define VP8_EFLAG_NO_UPD_LAST (1<<18)

Don't update the last frame.

When this flag is set, the encoder will not update the last frame with the contents of the current frame.

#define VP8_EFLAG_NO_UPD_GF (1<<22)

Don't update the golden frame.

When this flag is set, the encoder will not update the golden frame with the contents of the current frame.

#define VP8_EFLAG_NO_UPD_ARF (1<<23)

Don't update the alternate reference frame.

When this flag is set, the encoder will not update the alt ref frame with the contents of the current frame.

#define VP8_EFLAG_FORCE_GF (1<<19)

Force golden frame update.

When this flag is set, the encoder copy the contents of the current frame to the golden frame buffer.

#define VP8_EFLAG_FORCE_ARF (1<<24)

Force alternate reference frame update.

When this flag is set, the encoder copy the contents of the current frame to the alternate reference frame buffer.

#define VP8_EFLAG_NO_UPD_ENTROPY (1<<20)

Disable entropy update.

When this flag is set, the encoder will not update its internal entropy model based on the entropy of this frame.

typedef enum vpx_scaling_mode_1d VPX_SCALING_MODE

VP8E_SET_ROI_MAP	control function to pass an ROI map to encoder
VP8E_SET_ACTIVEMAP	control function to pass an Active map to encoder
VP8E_SET_SCALEMODE	control function to set encoder scaling mode
VP8E_SET_CPUUSED	control function to set vp8 encoder cpuused
VP8E_SET_ENABLEAUTOALTREF	control function to enable vp8 to automatic set and use altref frame
VP8E_SET_NOISE_SENSITIVITY	control function to set noise sensitivity
VP8E_SET_SHARPNESS	control function to set sharpness
VP8E_SET_STATIC_THRESHOLD	control function to set the threshold for macroblocks treated static
VP8E_SET_TOKEN_PARTITIONS	control function to set the number of token partitions
VP8E_GET_LAST_QUANTIZER	return the quantizer chosen by the encoder for the last frame using the internal scale
VP8E_GET_LAST_QUANTIZER_64	return the quantizer chosen by the encoder for the last frame, using the 0..63 scale as used by the rc_*_quantizer config parameters
VP8E_SET_ARNR_MAXFRAMES	control function to set the max number of frames blurred creating arf
VP8E_SET_ARNR_STRENGTH	control function to set the filter strength for the arf
VP8E_SET_ARNR_TYPE	control function to set the type of filter to use for the arf

enum vpx_scaling_mode_1d

vpx 1-D scaling mode

This set of constants define 1-D vpx scaling modes

enum vp8e_encoding_mode

VP8 encoding mode.

This defines VP8 encoding mode

enum vp8e_token_partitions

VP8 token partition mode.

This defines VP8 partitioning mode for compressed data, i.e., the number of sub-streams in the bitstream. Used for parallelized decoding.

vpx_codec_iface_t vpx_codec_vp8_cx_algo

Algorithm interface for VP8.

This interface provides the capability to encode raw VP8 streams, as would be found in AVI files.
