Hi Devin, Substituting ' >' for '>' had no effect. The command is: ffmpeg -y -safe 0 -i "c:\concat.txt" "c:\concat.ac3" echo this is foo>c:\FOO.TXT The thing that's bothering me so much is that while it's doing the concatenation, FFmpeg signals: Enter command: <target>|all <time>|-1 <command>[ <argument>] Parse error, at least 3 arguments were expected, only 1 given in string 'ho this is foo>c:\FOO.TXT' FFmpeg is clearly entering a command mode even though I'm not submitting any options that support command mode. --Mark. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
