pointers to the data planes/channels.
For video, this should simply point to data[].
For planar audio, each channel has a separate data pointer, and linesize[0] contains the size of each channel buffer. For packed audio, there is just one data pointer, and linesize[0] contains the total size of the buffer for all channels.
Note: Both data and extended_data will always be set, but for planar audio with more channels that can fit in data, extended_data must be used in order to access all channels.

A pointer to the function to deallocate this buffer if the default function is not sufficient.
This could, for example, add the memory back into a memory pool to be reused later without the overhead of reallocating it from scratch.
