Re: How to convert FLV to MP4 losslessly with ffmpeg (Windows, Linux, Mac OS)

No, it's different.
JC's version keeps the original soundtrack without converting it, so it's genuinely lossless conversion.
Your version converts the soundtrack to aac (even though it might already be aac), so it's not lossless conversion.
To keep the original soundtrack tweak your code like this:-
Code:
for %%a in ("*.flv") do ffmpeg -i "%%a" -c copy "newfiles\%%~na.mp4"
If the flv files don't contain aac (check this with MediaInfo program) then stay with your original code.
