[FFmpeg-user] feed ffmpeg with quicktime reference?

[Johannes Ramson]

is ffmpeg able to use quicktime reference clips (made with mediacomposer
and pointing to files at networkbase storages) as input?
I did some test with following results:

The quicktime-ref is pointing to op-atom mxf-files with avc-intra100 in it.
Unfortunately i dont know how to give you samples of these clips, cause if
i pick them out of my network the quicktime-ref wont find them in your
setting - right?

kind regards
