static void ff_amr_bit_reorder	(	uint16_t *	out,
		int	size,
		const uint8_t *	data,
		const R_TABLE_TYPE *	ord_table
	)			[inline, static]

Fill the frame structure variables from bitstream by parsing the given reordering table that uses the following format:.

Each field (16 bits) in the AMR Frame is stored as:

• one byte for the number of bits in the field
• one byte for the field index
• then, one byte for each bit of the field (from most-significant to least) of the position of that bit in the AMR frame.

Parameters:

	out	pointer to the frame struct
	size	the size in bytes of the frame struct
	data	input bitstream after the frame header
	ord_table	the reordering table as above
