int avpriv_aac_parse_header	(	GetBitContext *	gbc,
		AACADTSHeaderInfo *	hdr
	)

Parse AAC frame header.

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
