Function Documentation

int ff_hevc_parse_sps ( HEVCSPS sps,
GetBitContext gb,
unsigned int sps_id,
int  apply_defdispwin,
AVBufferRef **  vps_list,
AVCodecContext avctx 
)

Parse the SPS from the bitstream into the provided HEVCSPS struct.

Parameters
sps_idthe SPS id will be written here
apply_defdispwinif set 1, the default display window from the VUI will be applied to the video dimensions
vps_listif non-NULL, this function will validate that the SPS refers to an existing VPS
