Comment (by Thomas Mundt):

 I did some testing with the software XFConverter i got new at work.
 XFConverter wraps broadcast files into several containers. After
 rewrapping these files with the option "Store AVC-Intra header on each
 frame" set they can be decoded with ffmpeg.

 AVC Intra 100 file after rewrapping:[http://free-
 vsts.com/files/MXF/AVCI100_Test_xf.mxf]

 In the documentation of the software it is explained that Panasonic AVC-
 Intra streams have the SPS and the PPS only on the first frame. The option
 "Store AVC-Intra header on each frame" is repeating the SPS and the PPS
 found on the first frame on each frame.

 Could ffmpeg do the same trick, using the header from the first frame if
 the following frames doesn´t have one? The Panasonic AVC-Intra flavour has
 become standard for many broadcasters and is also used by AVID, Omneon and
 others...
