How can I keep the original video quality?

[GdavidPaella]

The question

I'd like to create an exact copy from a given audio or video file, keeping the quality, format, codec, framrate, bitrate, etc... (I just get bigger or smaller files, but can't get to get a file with the same attributes and size)

What you have tried

I'm trying to remove settings hoping it takes the original file values.

I also tried: .setConstantRateFactor(0)

Solution: (In case someone has the same issue)

FFmpegBuilder builder = new FFmpegBuilder()
...
.setAudioCodec("copy")
.setVideoCodec("copy")
