Constants
< camera video for real-time communication
< constant id in SPS/PPS
< end of stream flag
< indicate decoder error concealment method
< feedback current decoded frame number
< feedback decoder Sample Aspect Ratio info in Vui
< feedback decoder statistics
< feedback current frame belong to which IDR period
< feedback current frame is ref pic or not
< get current AU level info,only is used in GetOption
< feedback frame num marked by current Frame
< feedback wether current frame mark a LTR
< number of frames remaining in decoder buffer when pictures are required to re-ordered into display-order.
< number of decoding threads. The maximum thread count is equal or less than lesser of (cpu core counts and 16).
< get current AU profile info, only is used in GetOption
< set log output interval
< feedback temporal id for application layer
< a void ()(void context, int level, const char* message) function which receives log messages
< context info of trace callbac
< feedback whether or not have VCL NAL in current AU for application layer
< bit vary percentage
< the delivery info which is a feedback from app level
< dump layer reconstruct frame to a specified file
< enable prefix: true–enable prefix; false–disable prefix
< enable SSEI: true–enable ssei; false–disable ssei
< maximal input frame rate, current supported range: MAX_FRAME_RATE = 30,MIN_FRAME_RATE = 1
< read only
< IDR period,0/-1 means no Intra period (only the first frame); lager than 0 means the desired IDR period, must be multiple of (2^temporal_layer)
< advanced algorithmetic settings
< assgin the level for each layer
< 0:disable LTR;larger than 0 enable LTR; LTR number is fixed to be 2 in current encoder
< the number of refererence frame
< assgin the profile for each layer
< different stategy in adjust ID in SPS/PPS: 0- constant ID, 1-additional ID, 6-mapping and additional
< log interval in millisecond
< structure of Base Param
< structure of Extension Param
< a void ()(void context, int level, const char* message) function which receives log messages
< context info of trace callback
< trace info based on the trace level
< 0:disable padding;1:padding
< Forward Error Correction in 100% redundency mode
< Forward Error Correction in 50% redundency mode
< Flexible Macroblock Ordering
< IP Scalable
< Intra Refresh in predifined 2% MB
< Intra Refresh in predifined 5% MB
< Intra Refresh in predifined 10% MB
< NONE Error Tools
< Reference Frame Selection
< high complexity, lowest speed, high quality
< SPS/PPS id increases at each IDR
< the lowest compleixty,the fastest speed,
< medium complexity, medium speed,medium quality
< ref_idc == 0
< ref_idc != 0
< bitrate mode
< this is in-building RC MODE, WILL BE DELETED after algorithm tuning!
< no bitrate control,only using buffer status,adjust the video quality
< rate control off mode
< quality mode
< screen content signal
< | according to SliceNum | enabled dynamic slicing for multi-thread
< | according to SlicesAssign | need input of MB numbers each slice. In addition, if other constraint in SSliceArgument is presented, need to follow the constraints. Typically if MB num and slice size are both constrained, re-encoding may be involved.
< | SliceNum==1
< | according to SliceSize | slicing according to size, the slicing will be dynamic(have no idea about slice_nums until encoding current frame)
< using SPS in the existing list if possible
< debug log, critical algo log
< default log iLevel in Wels codec
< per packet/frame log
< error log iLevel
< information log iLevel
< quiet mode
< resversed log iLevel
< Warning log iLevel
< initial action is expected
< parameters are invalid
< malloc a memory error
< successful
< error bitstreams(maybe broken internal frame) the decoder cared
< current data error concealed specified
< dependented layer is ever lost
< actual picture size exceeds size of dst pBuffer feed in decoder, so need expand its size
< bit stream error-free
< need more throughput to generate a frame output,
< initializing operation is expected
< invalid argument specified
< no parameter set NALs involved
< out of memory due to new request
<ref picure list contains null ptrs within uiRefCount range
< layer lost at reference frame with temporal id 0
< the same as IYUV
< only used in SVC decoder testbed
< new format for output by DXVA decoding
< rgb color formats
< yuv color formats
< I frame type
< IDR frame in H.264
< a frame where I and P slices are mixing, not supported yet
< encoder not ready or parameters are invalidate
< P frame type
< skip the frame based encoder kernel
