(

ERContext *

s

)

ff_er_frame_end()

void ff_er_frame_end	(	ERContext *	s,
		int *	decode_error_flags
	)

Indicate that a frame has finished decoding and perform error concealment in case it has been enabled and is necessary and supported.

Parameters

s	ERContext in use
decode_error_flags	pointer where updated decode_error_flags are written if supplied; if not, the new flags are directly applied to the AVFrame whose errors are concealed

void ff_er_add_slice	(	ERContext *	s,
		int	startx,
		int	starty,
		int	endx,
		int	endy,
		int	status
	)

Add a slice.

Parameters

endx	x component of the last macroblock, can be -1 for the last of the previous line
status	the status at the end (ER_MV_END, ER_AC_ERROR, ...), it is assumed that no earlier end or error of the same type occurred
