Subject: Re: [ffmbc-discuss] Problem opening/transcoding MXF OP-Atom files
Since v0.7-rc5 was listed as the first entry in the download list, I
didn't see that rc7 already exists.
I've tried the same transcoding today with v0.7-rc7, and the problem
persists:

//-------------------
./ffmbc -i input/test_v1.mxf -acodec copy -vcodec copy test.avi

Mark Himsley told me that handling OP-Atom MXFs should work since v0.7-rc6.

Am I doing something wrong here?

Thanks,
