◆ ff_er_frame_start()

void ff_er_frame_start ( ERContext s)

Definition at line 787 of file error_resilience.c.

Referenced by ff_mpeg_er_frame_start(), and h264_frame_start().

◆ 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
sERContext in use
decode_error_flagspointer 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
endxx component of the last macroblock, can be -1 for the last of the previous line
statusthe status at the end (ER_MV_END, ER_AC_ERROR, ...), it is assumed that no earlier end or error of the same type occurred
