I am trying to concatenate two video files using ffmpeg, and am receiving and error.
Two eliminate compatibility issues between the two videos, I am been concatenating the same video with itself, and the same error persists.
ffmpeg -f concat -safe 0 -i intro_prepped.avi intro_prepped.avi -c copy concat.avi
And the error output I receive is....
[concat @ 0x220d420] Line 1: unknown keyword 'RIFFf�?' intro_prepped.avi: Invalid data found when processing input
I have tried various combinations of concat flags and have not been able to get it to work. Has anyone seen this error before?
