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

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.
Thank you. I wish I could understand these things more. I don't know how much script/program knowledge is required to make these command things work. I appreciate it. My first version kills Speex auto, so i will try this one.
