ffmpeg convert mkv to mp4 but keep original sound track

This example stream copies everything except for audio which is converted to AAC: ffmpeg -i input.mkv -map 0 -c copy -c:a aac output.If you want to convert MPG videos into MP4 format, you only need a proper video converter.

See the -map option documentation for more info.

Example to include everything except subtitles: ffmpeg -i input.mkv -map 0 -map -0:s -c copy output.mp4 Otherwise the default stream selection behavior is used which will only select one stream per stream type.įfmpeg will tell you if a stream is not compatible with the output container format with an error message: codec not currently supported in container.Ĭurrently the most typical compatible formats are: H.264 video, H.265/HEVC video, and AAC audio. map 0 selects all streams from input #0 which is input.mkv (note that ffmpeg starts counting from 0). ffmpeg -i input.mkv -map 0 -c copy output.mp4 You can remux with stream copy mode ( -c copy). If the streams in the MKV file are compatible with MP4 Sometimes input file has only 1 audio stream so to command line should be universal, I guess ffmpeg map with ? character. What command should I use to convert audio streams in order to achieve two a audio streams where will be pol and eng sound (not pol in both of them). Here are my commands: ffmpeg -i input.mkv -sn -map 0:a? -map 0:v -c:v copy -c:a? aac output.mp4įfmpeg -i input.mkv -sn -map 0 -c:v copy -c:a aac output.mp4įfmpeg -i input.mkv -sn -map 0:? -c:v copy -c:a aac output.mp4Įverything almost work but in output file I have 2 audio streams with name (pol) and (eng) but in both is sound from (pol) stream0:1. I tried few various command and output file is always the same (2 audio streams but in both sound from first audio stream). I would like to omit subtitles ( -sn option), copy video and encode audio streams to AAC. Stream #0:4(eng): Subtitle: hdmv_pgs_subtitle I have MKV file which contains: Stream #0:0(eng): Video: h264 (High)
