Author: Vittorio Giovara <[email protected]> Committer: Vittorio Giovara <[email protected]> Date: Wed Sep 2 18:59:38 2015 +0200 lavu: Remove bit packing from AVComponentDescriptor There is no practical benefit in having this structure elements bit packed given the size of the structure and its usage. Change types from uint16_t (packed) to plain int in order to simplify modifying the structure and accessing its fields.
