However, I'll try to approach this from a few angles. If "carib122813509mkv" refers to a specific file, perhaps a video file (given the ".mkv" extension), or a code used in a particular context, I'll provide a general framework for how one might explore such a topic. If it's something else entirely, please provide more context.
ffmpeg -v error -i "carib122813509mkv" -c copy "test_copy.mkv"
