However, from what I've seen -map_meta_data was just renamed to -map_metadata and I don't know if it is enabled by default. Could you please point me to the relevant poiece of ffmpeg documentation that says so? If it is confirmed, I'll be happy to merge this.

...the transcoding doesn't work with newer ffmpeg, the patch is fine. (sorry for bad wording)
