Replace audio stream from one file with audio stream from another
I have got two video files: .mp4, with a single (incorrect) audiostream, and an .mkv, with two audio streams (one incorrect, the other correct)
Is there a way to replace the audio of the .mp4 file with the second stream in the .mkv?
Thanks

You'd need to extract the audio from the MKV first and then combine remux the MP4 with the new track. Something like this should work:
ffmpeg -i vid.mkv -acodec copy -vn audio.ext
ffmpeg -i vid.mp4 -i audio.ext -vcodec copy -acodec copy -map 0:1 -map 1:0 final.mp4

Sure, with avconv (same as ffmpeg)
Try:
avconv -i INPUT_FILE_WITH_BROKEN_SOUND.mp4 -i SECOND_INPUT_FILE.mkv -c copy -map 0:v:0 -map 1:a:1 OUTPUT.mp4
-c copy copies tracks instead of re-encoding them
-map 0:v:0 selects track to be copied to output: 1st file -> video tracks -> 1st video track
-map 1:a:1 selects track to be copied to output: 2nd file -> audio tracks -> 2nd audio track
Hope it helps!

You'd need to extract the audio from the MKV first and then combine remux the MP4 with the new track. Something like this should work:
ffmpeg -i vid.mkv -acodec copy -vn audio.ext
ffmpeg -i vid.mp4 -i audio.ext -vcodec copy -acodec copy -map 0:1 -map 1:0 final.mp4
