[Vittorio Giovara]

ffmpeg | branch: master | Vittorio Giovara <vittorio.giovara at gmail.com> | Sat Feb 20 01:25:03 2016 -0500| [c2084ffcbfc11d1b6ed3a4a0df9cafd56fbb896f] | committer: Vittorio Giovara

This is assuming that intrax8 has no support for interlacing
Carry over lowdelay value in ff_intrax8_decode_picture.
