    I am trying to add 2 external audios to my mkv file, but I don't want anything reencoded.
    So I tried
    Code:
    ffmpeg.exe -i input.mkv -i audio1.ac3 -i audio2.ac3 -map 0:0 -map 0:1 -map 1:0 -map 2:0 -c:v copy -c:a copy Output.mkv
    In the window that opens, I can see it is encoding the video:

    Code:
    frame=15285 fps=910 q=-1.0 Lsize=  911531kB time=00:10:37.51 bitrate=11713.1kbits/s speed=  38x
    What's going on?

    That is the standard FFmpeg display for any kind of muxing, whether you are encoding or not. It does not imply that the copy flag is being ignored.
