Changed audio language with mkpropedit but ffmpeg doesn't recognize it
This file has a single audio stream. It's language was undefined before.
mkvpropedit 'file.mkv' --edit track:2 --set language=por. All went fine. Mediainfo also sees the language as por.
But ffmpeg can't. I'm using
ffmpeg version N-52628-g79e3c4dd74-static and
