Hi Group
We are currently using ffmpeg to 'chop' IMX files(e.g multiple news clips)
into individual clips, using the following ffmpeg -map command :-
{{{
>ffmpeg -i D:\OwenMoneyTape\30PC60746MBIB6527895.mov -ss 00:02:00.000
-scodec copy -map 0:6 -vcodec copy -map 0:1 -acodec copy -map 0:2 -map
0:3 -map 0:4 -map 0:5 -metadata creation_time="2014-05-01 12:00:00" -to
00:03:00.000 -y /tmp/clip.mov -report
}}}
The input file contains a video track, 4 audio tracks and a timecode track
and we are mapping all tracks to the output clip.
On running mediainfo v0.7.69 on the input file and the output clipped
file, we are finding that FFmpeg is adding mediainfo field
'ChannelPositions' field automatically in the output.( note does does
exist in input IMX file)
It appears that ffmpeg is guessing the Audio Channel Layout Is there a way
to prevent FFmpeg to output the Audio Channel or am I using the -map
command incorrectly. ?
( note the all the other fields are spot on and as expected)
Many thanks
Richard Williams
