Main external API structure. New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. sizeof(SwsContext) is not part of the ABI.

Fields

av_class: *const AVClass

opaque: *mut c_void

Private data of the user, can be used to carry app specific stuff.
