Comment (by Thomas Mundt):

 The patch works! Also with other AVCI100/1080i files we´ve got on our
 server. Thanks for that!
 Unfortunatly the colors look kind of inconsistant. Since this is also
 visible with the rewrapped files it could be a general problem of the
 ffmpeg h264 decoder!?

 I´ve uploaded some AVCI 720p samples:
 AVCI100 Omneon file: [http://free-vsts.com/files/MXF/AVCI100_720p.mxf]
 AVCI100 rewrapped: [http://free-vsts.com/files/MXF/AVCI100_720p_xf.mxf]
 AVCI50 Omneon file: [http://free-vsts.com/files/MXF/AVCI50_720p.mxf]
 AVCI50 rewrapped: [http://free-vsts.com/files/MXF/AVCI50_720p_xf.mxf]

 There seems to be a problem with the AVCI50 header again, but maybe you
 can find the bug.

 Potentially the files can also help with ticket #1666 since it is
 progressive material. I cannot record in 1080p25 and the wrapper doesn´t
 accept AVCI in MOV-container.
