Windows 10: How can I use ffmpeg commands in QWinFF?

I’ve just started using QWinFF and I was trying to combine an audio and video file together with it.
As I know that it supports ffmpeg commands, I tried using the “ffmpeg -i video.mp4 -i audio.m4a -c:v copy -c:a copy output.mp4” command in the advanced tab. Didn’t work!
Does someone have any idea what is the correct way to use ffmpeg commands in QWinFF?

Videos Wrong way round: N95 8Gb

I use ffmpeg for that. But beware that it's a command line tool, not a pointy clicky thing.

I use ffmpeg for all transcoding tasks. It's a command line (and therefore scriptable) tool easily found with google. The command line I'd issue is probably something like this:

ffmpeg -i input.mp4 -target pal-dvd -aspect 4:3 -ab 192k -ac 2 output.mpg

And then use whatever standard tools on your system (if it's windows I can't help you) to embed the mpeg data in a DVD structure and burn it to a disc.

 

I use FFmpeg 'raw', as it were. You have missed out the commands that tells it how to map the video and audio streams to the output file. Try:

ffmpeg -i video.mp4 -i audio.m4a -map 0:0 -map 1:0 -c:v copy -c:a copy output.mp4

This says map input 0 stream 0 (your video) to the output's stream 0, and input 1, stream 0 (your audio) to the output's stream 1.

Also, I have had a few cases where the '-c:a copy' has caused problems. If it still doesn't work, leave that out and let FFmpeg recode the audio.
