Function Documentation

ff_adts_header_parse()

int ff_adts_header_parse	(	GetBitContext *	gbc,
		AACADTSHeaderInfo *	hdr
	)

Parse the ADTS frame header to the end of the variable header, which is the first 54 bits.

Parameters

[in]	gbc	BitContext containing the first 54 bits of the frame.
[out]	hdr	Pointer to struct where header info is written.

Returns

Returns 0 on success, -1 if there is a sync word mismatch, -2 if the version element is invalid, -3 if the sample rate element is invalid, or -4 if the bit rate element is invalid.

avpriv_adts_header_parse()

int avpriv_adts_header_parse	(	AACADTSHeaderInfo **	phdr,
		const uint8_t *	buf,
		size_t	size
	)

Parse the ADTS frame header contained in the buffer, which is the first 54 bits.

Parameters

[in]	buf	Pointer to buffer containing the first 54 bits of the frame.
[in]	size	Size of buffer containing the first 54 bits of the frame.
[out]	phdr	Pointer to pointer to struct AACADTSHeaderInfo for which memory is allocated and header info is written into it. After using the header information, the allocated memory must be freed by using av_free.

Returns

Returns 0 on success, -1 if there is a sync word mismatch, -2 if the version element is invalid, -3 if the sample rate element is invalid, or -4 if the bit rate element is invalid.
