[Vittorio Giovara]

ffmpeg | branch: master | Vittorio Giovara <vittorio.giovara at gmail.com> | Mon Apr 27 19:13:27 2015 +0100| [9c1db92ad372d4cd69e0490e691c56e4097cb193] | committer: Vittorio Giovara

mpegvideo: Drop err_recognition

It is just a duplicate of an AVCodecContext member so use it instead.
