Author: Vittorio Giovara <[email protected]> Committer: Vittorio Giovara <[email protected]> Date: Thu Jun 9 18:35:03 2016 -0400 avpacket: Error out when creating 0-sized side data This mimics the behaviour of other av_*_new_side_data(). This is not caught by the malloc check, since padding is always added to the allocated size.
