#vpx_codec_control

Enumerator
VP8E_SET_ROI_MAP	Codec control function to pass an ROI map to encoder. Supported in codecs: VP8
VP8E_SET_ACTIVEMAP	Codec control function to pass an Active map to encoder. Supported in codecs: VP8, VP9
VP8E_SET_SCALEMODE	Codec control function to set encoder scaling mode. Supported in codecs: VP8, VP9
VP8E_SET_CPUUSED	Codec control function to set encoder internal speed settings. Changes in this value influences, among others, the encoder's selection of motion estimation methods. Values greater than 0 will increase encoder speed at the expense of quality. Note Valid range for VP8: -16..16 Valid range for VP9: -9..9 Supported in codecs: VP8, VP9
VP8E_SET_ENABLEAUTOALTREF	Codec control function to enable automatic use of arf frames. Note Valid range for VP8: 0..1 Valid range for VP9: 0..6 Supported in codecs: VP8, VP9
VP8E_SET_NOISE_SENSITIVITY	control function to set noise sensitivity 0: off, 1: OnYOnly, 2: OnYUV, 3: OnYUVAggressive, 4: Adaptive Supported in codecs: VP8
VP8E_SET_SHARPNESS	Codec control function to set higher sharpness at the expense of a lower PSNR. Note Valid range: 0..7 Supported in codecs: VP8, VP9
VP8E_SET_STATIC_THRESHOLD	Codec control function to set the threshold for MBs treated static. Supported in codecs: VP8, VP9
VP8E_SET_TOKEN_PARTITIONS	Codec control function to set the number of token partitions. Supported in codecs: VP8
VP8E_GET_LAST_QUANTIZER	Codec control function to get last quantizer chosen by the encoder. Return value uses internal quantizer scale defined by the codec. Supported in codecs: VP8, VP9
VP8E_GET_LAST_QUANTIZER_64	Codec control function to get last quantizer chosen by the encoder. Return value uses the 0..63 scale as used by the rc_*_quantizer config parameters. Supported in codecs: VP8, VP9
VP8E_SET_ARNR_MAXFRAMES	Codec control function to set the max no of frames to create arf. Supported in codecs: VP8, VP9
VP8E_SET_ARNR_STRENGTH	Codec control function to set the filter strength for the arf. Supported in codecs: VP8, VP9
VP8E_SET_ARNR_TYPE	Deprecated: control function to set the filter type to use for the arf.
VP8E_SET_TUNING	Codec control function to set visual tuning. Supported in codecs: VP8, VP9
VP8E_SET_CQ_LEVEL	Codec control function to set constrained / constant quality level. Attention For this value to be used vpx_codec_enc_cfg_t::rc_end_usage must be set to VPX_CQ or VPX_Q Note Valid range: 0..63 Supported in codecs: VP8, VP9
VP8E_SET_MAX_INTRA_BITRATE_PCT	Codec control function to set Max data rate for Intra frames. This value controls additional clamping on the maximum size of a keyframe. It is expressed as a percentage of the average per-frame bitrate, with the special (and default) value 0 meaning unlimited, or no additional clamping beyond the codec's built-in algorithm. For example, to allocate no more than 4.5 frames worth of bitrate to a keyframe, set this to 450. Supported in codecs: VP8, VP9
VP8E_SET_FRAME_FLAGS	Codec control function to set reference and update frame flags. Supported in codecs: VP8
VP9E_SET_MAX_INTER_BITRATE_PCT	Codec control function to set max data rate for Inter frames. This value controls additional clamping on the maximum size of an inter frame. It is expressed as a percentage of the average per-frame bitrate, with the special (and default) value 0 meaning unlimited, or no additional clamping beyond the codec's built-in algorithm. For example, to allow no more than 4.5 frames worth of bitrate to an inter frame, set this to 450. Supported in codecs: VP9
VP9E_SET_GF_CBR_BOOST_PCT	Boost percentage for Golden Frame in CBR mode. This value controls the amount of boost given to Golden Frame in CBR mode. It is expressed as a percentage of the average per-frame bitrate, with the special (and default) value 0 meaning the feature is off, i.e., no golden frame boost in CBR mode and average bitrate target is used.

VP8E_SET_TEMPORAL_LAYER_ID	Codec control function to set the temporal layer id. For temporal scalability: this control allows the application to set the layer id for each frame to be encoded. Note that this control must be set for every frame prior to encoding. The usage of this control function supersedes the internal temporal pattern counter, which is now deprecated. Supported in codecs: VP8
VP8E_SET_SCREEN_CONTENT_MODE	Codec control function to set encoder screen content mode. Supported in codecs: VP8
VP9E_SET_LOSSLESS	Codec control function to set lossless encoding mode. VP9 can operate in lossless encoding mode, in which the bitstream produced will be able to decode and reconstruct a perfect copy of input source. This control function provides a mean to switch encoder into lossless coding mode(1) or normal coding mode(0) that may be lossy. 0 = lossy coding mode 1 = lossless coding mode By default, encoder operates in normal coding mode (maybe lossy). Supported in codecs: VP9
VP9E_SET_TILE_COLUMNS	Codec control function to set number of tile columns. In encoding and decoding, VP9 allows an input image frame be partitioned into separated vertical tile columns, which can be encoded or decoded independently. This enables easy implementation of parallel encoding and decoding. This control requests the encoder to use column tiles in encoding an input frame, with number of tile columns (in Log2 unit) as the parameter: 0 = 1 tile column 1 = 2 tile columns 2 = 4 tile columns ..... n = 2**n tile columns The requested tile columns will be capped by encoder based on image size limitation (The minimum width of a tile column is 256 pixel, the maximum is 4096).

VP9E_SET_TILE_ROWS	Codec control function to set number of tile rows. In encoding and decoding, VP9 allows an input image frame be partitioned into separated horizontal tile rows. Tile rows are encoded or decoded sequentially. Even though encoding/decoding of later tile rows depends on earlier ones, this allows the encoder to output data packets for tile rows prior to completely processing all tile rows in a frame, thereby reducing the latency in processing between input and output. The parameter for this control describes the number of tile rows, which has a valid range [0, 2]: 0 = 1 tile row 1 = 2 tile rows 2 = 4 tile rows By default, the value is 0, i.e. one single row tile for entire image. Supported in codecs: VP9
VP9E_SET_FRAME_PARALLEL_DECODING	Codec control function to enable frame parallel decoding feature. VP9 has a bitstream feature to reduce decoding dependency between frames by turning off backward update of probability context used in encoding and decoding. This allows staged parallel processing of more than one video frames in the decoder. This control function provides a mean to turn this feature on or off for bitstreams produced by encoder. By default, this feature is off. Supported in codecs: VP9
VP9E_SET_AQ_MODE	Codec control function to set adaptive quantization mode. VP9 has a segment based feature that allows encoder to adaptively change quantization parameter for each segment within a frame to improve the subjective quality.

VP9E_SET_FRAME_PERIODIC_BOOST	Codec control function to enable/disable periodic Q boost. One VP9 encoder speed feature is to enable quality boost by lowering frame level Q periodically. This control function provides a mean to turn on/off this feature. 0 = off 1 = on By default, the encoder is allowed to use this feature for appropriate encoding modes. Supported in codecs: VP9
VP9E_SET_NOISE_SENSITIVITY	Codec control function to set noise sensitivity. 0: off, 1: On(YOnly) Supported in codecs: VP9
