GstCodecParsers.AV1LoopFilterParams

Fields

Name	Type	Access	Description
delta_lf_multi	int	r/w	equal to 1 specifies that separate loop filter deltas are sent for horizontal luma edges, vertical luma edges, the U edges, and the V edges. delta_lf_multi equal to 0 specifies that the same loop filter delta is used for all edges.
delta_lf_present	bool	r/w	specifies whether loop filter delta values are present in the bitstream.
delta_lf_res	int	r/w	specifies the left shift which should be applied to decoded loop filter delta values.
loop_filter_delta_enabled	bool	r/w	equal to 1 means that the filter level depends on the mode and reference frame used to predict a block. loop_filter_delta_enabled equal to 0 means that the filter level does not depend on the mode and reference frame.
loop_filter_delta_update	bool	r/w	equal to 1 means that the bitstream contains additional syntax elements that specify which mode and reference frame deltas are to be updated. loop_filter_delta_update equal to 0 means that these syntax elements are not present.
loop_filter_level	bytes	r/w	is an array containing loop filter strength values. Different loop filter strength values from the array are used depending on the image plane being filtered, and the edge direction (vertical or horizontal) being filtered.
loop_filter_mode_deltas	[int]	r/w	contains the adjustment needed for the filter level based on the chosen mode. If this syntax element is not present in the bitstream, it maintains its previous value.
loop_filter_ref_deltas	[int]	r/w	contains the adjustment needed for the filter level based on the chosen reference frame. If this syntax element is not present in the bitstream, it maintains its previous value.
loop_filter_sharpness	int	r/w	indicates the sharpness level. The loop_filter_level and loop_filter_sharpness together determine when a block edge is filtered, and by how much the filtering can change the sample values. The loop filter process is described in AV1 Bitstream Spec. section 7.14.
