22 * refcounted data buffer API
36 * AVBuffer is an API for reference-counted data buffers.
39 * represents the data buffer itself; it is opaque and not meant to be accessed
42 * are describing the same data buffer. AVBufferRef represents a single
51 * data once all the references are freed).
67 * parts of the buffer (i.e. their AVBufferRef.data will not be equal).
77 * A reference to a data buffer.
86 * The data buffer. It is considered writable if and only if
90 uint8_t *data;
92 * Size of data in bytes.
119 * If this function is successful, data is owned by the AVBuffer. The caller may
120 * only access data through the returned AVBufferRef and references derived from
122 * If this function fails, data is left untouched.
123 * @param data data array
124 * @param size size of data in bytes
125 * @param free a callback for freeing this buffer's data
129 * @return an AVBufferRef referring to data on success, NULL on failure.
