[FFmpeg-user] Reversed stream order of video audio after audio merging

[Christoph Gerstbauer]

Hello,

I have multiple MXF files where first track is video und following 
tracks are audio which have to me merged to one audio output stream:
e.g.: Inputfile has
0:0 video
0:1 audio
0:2 audio
0:3 audio
0:4 audio

When I merge the multiple audio channel from an MXF file to one audio 
output stream I get following:

0:0 audio
0:1 video

How can I force that ffmpeg outputs always a video file where the video 
stream is on first place (0:0)?

Best Regards
Christoph

Commandline output:
