vjk2005 / dual_audio_video_to_youtube.sh

Created July 23, 2017 09:36

How to upload Japanese audio instead of English from a dual-audio video to YouTube (BONUS: convert to MP4 format as well in the same step)

	ffmpeg -i <input.mkv> -map 0:0 -map 0:2 -c copy <output.mp4>
	# 0:0 is the video stream to be copied as -map syntax is <input no>:<stream no>
	# 0:1 is the English audio stream, skip this and map 0:2, the Japanese audio stream, to the output.
	# You can see the stream info with their id by running ffmpeg -i <input.mkv>
	# BONUS: convert MKV to MP4 right here with this single command
