|
* Blocks of binary data.
|
|
*
|
|
* @ref block_t is a generic structure to represent a binary blob within VLC.
|
|
* The primary goal of the structure is to avoid memory copying as data is
|
|
* passed around.
|
|
*
|
|
* It is notably used in:
|
|
* - access_t
|
|
* - stream_t
|
|
* - demux_t (read block_t but send vlc_frame_t from es_out_Send)A
|
|
*
|
|
* TODO: remove the vlc_frame_t typedef and create a block_t struct like the
|
|
* following:
|
|
* @verbatim
|
|
* struct block_t
|
|
* {
|
|
* struct block_t *p_next;
|
|
* uint8_t *p_buffer;
|
|
* size_t i_buffer;
|
|
* uint8_t *p_start;
|
|
* size_t i_size;
|
|
* const struct block_callbacks *cbs;
|
|
* } @endverbatim
