* FIXME: We need native structure access methods to deal with API changes

* Currently we are binary compatible w/ [0.6 ?, ] 0.7 and 0.8 but not w/ trunk.
*
* ChangeList for trunk:
* Thu Jan 12 11:21:02 2012 a17479dfce67fbea2d0a1bf303010dce1e79059f major 53 -> 54
* Mon Feb 27 22:40:11 2012 ee42df8a35c2b795f524c856834d0823dbd4e75d reorder AVStream and AVFormatContext
* Tue Feb 28 12:07:53 2012 322537478b63c6bc01e640643550ff539864d790 minor 1 -> 2
