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.
