Hi everybody!

I try to wrap an mxf File with 8 mono audio channels to one
with the same video content and a stereo audio track from the first two
mono tracks:

ffmpeg -y -i input.mxf -c:v copy -filter_complex amerge c:\temp\test.mxf

The syntax seems to be o.k. but i get the following output:

If i do not use the amerge Filter, it works and i get an output file with
one mono audio channel:

ffmpeg -y -i input.mxf -c:v copy c:\temp\test.mxf

The difference is, that in the first case, the output of amerge will become
the
Stream #0:0 to the mxf wrapper, which seems not to be allowed!
In the second case video will become the Stream #0:0 and everything
seems to work.
I didn't find a way to change the streams in the mxf wrapper.
Can you help me in that case?

Thank you, Georg Korger
