Go to the source code of this file.
Data Structures | |
| struct | SpeexBits |
| Bit-packing data structure representing (part of) a bit-stream. More... | |
Typedefs | |
| typedef struct SpeexBits | SpeexBits |
| Bit-packing data structure representing (part of) a bit-stream. | |
Functions | |
| void | speex_bits_init (SpeexBits *bits) |
| Initializes and allocates resources for a SpeexBits struct. | |
| void | speex_bits_init_buffer (SpeexBits *bits, void *buff, int buf_size) |
| Initializes SpeexBits struct using a pre-allocated buffer. | |
| void | speex_bits_set_bit_buffer (SpeexBits *bits, void *buff, int buf_size) |
| Sets the bits in a SpeexBits struct to use data from an existing buffer (for decoding without copying data) | |
| void | speex_bits_destroy (SpeexBits *bits) |
| Frees all resources associated to a SpeexBits struct. | |
| void | speex_bits_reset (SpeexBits *bits) |
| Resets bits to initial value (just after initialization, erasing content) | |
| void | speex_bits_rewind (SpeexBits *bits) |
| Rewind the bit-stream to the beginning (ready for read) without erasing the content. | |
| void | speex_bits_read_from (SpeexBits *bits, char *bytes, int len) |
| Initializes the bit-stream from the data in an area of memory. | |
| void | speex_bits_read_whole_bytes (SpeexBits *bits, char *bytes, int len) |
| Append bytes to the bit-stream. | |
| int | speex_bits_write (SpeexBits *bits, char *bytes, int max_len) |
| Write the content of a bit-stream to an area of memory. | |
| int | speex_bits_write_whole_bytes (SpeexBits *bits, char *bytes, int max_len) |
| Like speex_bits_write, but writes only the complete bytes in the stream. | |
| void | speex_bits_pack (SpeexBits *bits, int data, int nbBits) |
| Append bits to the bit-stream. | |
| int | speex_bits_unpack_signed (SpeexBits *bits, int nbBits) |
| Interpret the next bits in the bit-stream as a signed integer. | |
| unsigned int | speex_bits_unpack_unsigned (SpeexBits *bits, int nbBits) |
| Interpret the next bits in the bit-stream as an unsigned integer. | |
| int | speex_bits_nbytes (SpeexBits *bits) |
| Returns the number of bytes in the bit-stream, including the last one even if it is not "full". | |
| unsigned int | speex_bits_peek_unsigned (SpeexBits *bits, int nbBits) |
| Same as speex_bits_unpack_unsigned, but without modifying the cursor position. | |
| int | speex_bits_peek (SpeexBits *bits) |
| Get the value of the next bit in the stream, without modifying the "cursor" position. | |
| void | speex_bits_advance (SpeexBits *bits, int n) |
| Advances the position of the "bit cursor" in the stream. | |
| int | speex_bits_remaining (SpeexBits *bits) |
| Returns the number of bits remaining to be read in a stream. | |
| void | speex_bits_insert_terminator (SpeexBits *bits) |
| Insert a terminator so that the data can be sent as a packet while auto-detecting the number of frames in each packet. | |
