Comment (by laurfb):
Hi. I do some more test with XDCAM MXF files using ffmbc/ffmpeg and the
latest SONY browsers/viewers. Yes, the MXF files are loaded and played
without any error, but:
From what I know MXF was developed as an exchange standard in broadcast
industry.
However the flexibility of format lead sometime to interoperability issue:
MXF files produced by some equipment/producers (like Sony for ex.) is not
necessarely understood by all apps that claim to support MXF standards,
most often due to obscure subformat options behind MXF extension.
Recently one of my friend had some compatibility issue using ffmpeg/ffmbc
with some particular application (playout automation system from http
://si-media.tv/) - the MXF files can't be loaded ("unsuported format") and
the only solution I found is to re-wrap MXF files (generated either with
ffmpeg or ffmbc) with bmxlib.
I must say that all the MXF files generated with ffmpeg/ffmbc (e.g. files
uploaded on zippyshare) are well played on few other proffesional grade
apps I used (Drastic Preview, Cinegy, Sony Viewer).
Also, the initial issue reported by Axel Technology I think is related to
their XTV automation&playout systems (http://www.axeltechnology.com).
I don't have acces to such playouts systems (simedia or axel) so I can't
help with furter tests if needed.
I think the only solution to maximize the overall ffmpeg mxf compatibility
is to use the bmxlibs (based on BBC R&D specs as far as I know) which, I
hope, will eliminate the majority of problems encountered.
Don't know if someone will have more time to investigate that matter but I
think it would be useful to extend the overall ffmpeg compatibility.
Thanks for your work!
best regards,
laur
