MXF DV from AAF (Avid) not demuxable

[Ignasi Rius]

I am uploading the file MXF_DVCAM_not_demuxable.mxf to the FTP which causes the problem.

To reproduce the problem just type:

ffplay -v 9 -loglevel 99 -i Olimpic_Games.mxf

ffplay version 1.2 Copyright (c) 2003-2013 the FFmpeg developers
  built on Mar 28 2013 00:31:28 with gcc 4.8.0 (GCC)

This file starts playing (with ffplay) fine, but after 5 or 6 seconds the following error message shows up:

[mxf @ 01a07a00] KLV for edit unit 123 extends into next edit unit - OPAtom misinterpreted as OP1a?
[mxf @ 01a07a00] If you want to help, upload a sample of this file to ftp://upload.ffmpeg.org/MPlayer/incoming/ and contact the ffmpeg-devel mailing list.

VLC can decode the file as well as other profesisonal video editors (Edius, other).

The exact same issue happens when using the ffmpeg API directly, or the ffmpeg.exe tool.
Actually, the file was generated from and Avid AAF by means of a MXF Mainconcept multiplexer (SDK version 9.5). I believe the file is fine as it is playable with vlc, editable with Edius and other profesisonal video editors.
Mainconcept's MXF Demuxer also can read the file fine.

Please test current git head and please add the complete, uncut console output to make this a valid ticket.

Sorry. I've just tested with today's Zeranoe build, and the error message changed slightly. It basically says that something might not be implemented yet.

Here's what I get (I had to cut the output because the last message is repeated for each KLV unit):
