Manually recode audio with ffmpeg works fine, e.g.:

ffmpeg -i "video.mkv" -c:v copy -c:a aac "video_new.mkv"

This is needed for Serviio to correctly handle WebM content (which is VP9 video and Opus audio in Matroska container with specific options set). Since WebM is the only non-patent-encumbered HTML5 video format I think it's important for Serviio to integrate support. I also have some kids TV programmes encoded in this format :)
