Function Documentation

ff_itut_t35_parse_buffer()

int ff_itut_t35_parse_buffer	(	FFITUTT35 *	itut_t35,
		const uint8_t *	buf,
		size_t	size,
		int	flags
	)

Parse a raw ITU-T T35 buffer to get the country code, provider code, and set them plus the pointer and size in the FFITUTT35 struct to the start of the actual payload.

Parameters

itut_t35	The struct to fill
buf	The input buffer
size	Size of the input buffer
flags	A combination of FF_ITUT_T35_FLAG_*

Returns

0 if nothing was done (e.g. the payload is of an unsupported type), 1 on success, or a negative AVERROR code on failure

Note

buf will remain owned by the caller, and no new allocations will be made. Any pointer in the resulting struct will be valid as long as buf is valid.

ff_itut_t35_parse_payload_to_struct()

int ff_itut_t35_parse_payload_to_struct	(	FFITUTT35 *	itut_t35,
		FFITUTT35Aux *	aux,
		FFITUTT35Meta *	metadata,
		int	err_recognition
	)

Parse a pre-processed ITU-T T35 payload to fill the metadata struct.

Parameters

itut_t35	The pre-filled struct
aux	A struct containing extra contexts required by certain payload types. Any pointer present is owned by the caller. May be NULL, in which case the relevant payloads will not be parsed.
metadata	A metadata struct. All the allocated buffer references are owned by the caller and must be freed accordingly.
err_recognition	A combination of AV_EF_* flags

Returns

0 on success, or a negative AVERROR code on failure

ff_itut_t35_parse_payload_to_frame()

		FFITUTT35Aux *	aux,
		AVCodecContext *	avctx,
		AVFrame *	frame
	)

Parse a pre-processed ITU-T T35 payload to fill a frame's side data.

Parameters

itut_t35	The pre-filled struct
aux	A struct containing extra contexts required by certain payload types. Any pointer present is owned by the caller. May be NULL, in which case the relevant payloads will not be parsed.
avctx	The context that generated the frame
frame	A frame

Returns

0 on success, or a negative AVERROR code on failure
