Keeping only the video, English audio and subtitles however encode the video (fast crf 25): ffmpeg -i inputfile.mkv -map 0:0 -map 0:1 -map 0:2 -c:v libx264 -preset fast -crf 25 -c:a copy -c:s copy english-output.mp4 Making a French only audio copy with: ffmpeg -i inputfile.mkv -map 0:3 french-audio.mp3 Ī simple FFmpeg map example to create an audio only and then a video only copy from the input: ffmpeg -i inputfile.mkv -map 0:1 audio.mp3 -map 0:0 video.mp4īecause Stream #0:1 is the audio stream and #0:0 is the video stream. You will see (depending on your input file) multiple streams, they look like: Stream #0:0: Video: hevc. Run ffmpeg -i inputfile to see all the information about the media. Video usually has different streams for quality when it is a live stream. #FFMPEG MAP BDPG MOVIE#Streams means video, audio, subtitles, attachments and data within the file this is rather complex on movie files where there could be multiple audio streams for different languages and the same for subtitles. Map in FFmpeg can be best understood as selecting streams within a file you want to encode, keep or remove when creating an output. ![]()
