v4l2_vp9_ada...oncoef_probs(9)
okay so bestie, welcome to the v4l2_vp9_ada...oncoef_probs(9) page in the Kernel API Manual β yes, the full function is v4l2_vp9_adapt_noncoef_probs, and this page is literally about doing a backward update of the vp9 non-coefficients probabilities. stay with me, it's gonna slay β¨
πΈ NAME πΈ
v4l2_vp9_adapt_noncoef_probs β perform backward update of vp9 non-coefficients probabilities. periodt π
β¨ SYNOPSIS β¨
void v4l2_vp9_adapt_noncoef_probs (struct v4l2_vp9_frame_context *probs
, struct v4l2_vp9_frame_symbol_counts *counts , u8 reference_mode , u8
interpolation_filter , u8 tx_mode , u32 flags );
π ARGUMENTS π
probsβ the current probabilities values. that's the vibe.countsβ values of symbol counts after the current frame has been decoded. yes bestie, the receipts after decoding.reference_modeβ specifies the type of inter prediction to be used. seev4l2_vp9_reference_modefor more details.interpolation_filterβ specifies the filter selection used for performing inter prediction. seev4l2_vp9_interpolation_filterfor more details.tx_modeβ specifies the TX mode. seev4l2_vp9_tx_modefor more details.flagsβ a combination ofV4L2_VP9_FRAME_FLAG_*flags.
π¦ DESCRIPTION π¦
this function performs backward updates of non-coefficients probabilities for the vp9 boolean decoder. after a frame has been decoded, the counts of how many times a given symbol has occurred are known, and they're used to update the probability of each symbol. lowkey iconic: the frame hands over the receipts, and the probabilities get their little update. no cap, that's the whole function π«Ά
