[FFmpeg-user] Need help resolving concat error

[Mark Strecker]

Hello All,

I am new to ffmpeg and need help resolving an error. We are trying to
concatenate MOV files and figured out the options we need on Windows. We
then tried it on OS X and ran into problems. We are using the latest
version downloaded from the ffmpeg site : 3.1.1

 Here is the command line we tried originally (this is the one we intend to
use and works on Windows ... except the file input of course):

*ffmpeg -safe 0 -analyzeduration 4000000000 -probesize 4000000000 -i <(for
f in ./*.MOV; do echo "file '$PWD/$f'"; done) -map 0:0 -map 0:1 -map 0:2
-c:v copy -c:a copy -map_metadata 0 -copy_unknown -disposition:a:0 default
-disposition:a:1 default OUT.MOV*

*/dev/fd/63: Invalid data found when processing input*


So we changed to command to use an input file and simplify a bit. It seems
to get further, but we now get a codec error :


*ffmpeg -i files.txt -c:v copy -c:a copy OUT.MOV*

TIA for your help!
