ff_amr_bit_reorder()

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

inlinestatic

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
