/**
* The buffer reference to the frame sent across the link by the
* source filter, which is read by the destination filter. It is
* automatically set up by ff_start_frame().
*
* Depending on the permissions, it may either be the same as
* src_buf or an automatic copy of it.
*
* It is automatically freed by the filter system when calling
* ff_end_frame(). In case you save the buffer reference
* internally (e.g. if you cache it for later reuse), or give it
* away (e.g. if you pass the reference to the next filter) it
* must be set to NULL before calling ff_end_frame().
