How to create still image with sound video with ffmpeg with no transcoding audio so that my audio would be left untouched, so there is no loss in quality. I tried with a lot of parameters and couldnt't find one i've tried
ffmpeg -loop 1 -i image.jpg -i audio.mp3 -shortest -c copy output.mkv
but audio does not sound the same when downloading it from a website and playing it. can someone help me? some examples of no transcoding audio parameters?
