Fix Unsafe File Name when run ffmpeg command

September 11, 2018 IT Support 1 Comment

When you’re run ffmpeg command and receive an error message similar to the following:

Unsafe file name '00 M00S.mp4'
mylist.txt: Operation not permitted

This is because there is space in target filename in the text file. To fix this issue, add

-safe 0

before

-i

If you have this issue from Combine MP4 files using FFMPEG on Windows (without re-encoding), simply replace command in step 7 to the following:

ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4
