  • -b:a 384k 384k bitrate (I don't know what's good for aac stereo but this is really high since it's for 5.1 aac)Ī video with two audio streams.

    Important! You must change the output channel to a higher number if there are multiple audio streams to prevent overwriting them. -c:a:1 aac Output the audio to a 2nd audio channel (0 = first channel) in aac format.-map 0:a:0 Tell ffmpeg to read the first audio stream for the following arguments.

  • -map 0 Tell ffmpeg read all Video, Audio, and Subtitle streams for the following arguments.
  • ffmpeg -i INPUT.mkv The application and input file.
    • It will be in AAC anycodings_ffmpeg 384k.įfmpeg -i INPUT.mkv -strict -2 -map 0 -c anycodings_ffmpeg copy -map 0:a:0 -c:a:1 aac -b:a 384k -ac anycodings_ffmpeg 2 OUTPUT.mkv Explanation of the command This command will take a video with 1 anycodings_ffmpeg audio stream, and downmix to stereo and anycodings_ffmpeg convert the audio stream and add it as a anycodings_ffmpeg 2nd audio stream. Maybe someone anycodings_ffmpeg have more knowledge about it? 0 T21:15:24+00:00 T21:15:24+00:00 Answer Link It is not a great encoder, but it is not too bad at higher bitrates.Īccording to wikipedia, there is no anycodings_ffmpeg difference between AC3 and ATSC A/52: anycodings_ffmpeg the 1st one is the name of the codec, anycodings_ffmpeg the 2nd is the name of the standard anycodings_ffmpeg specifying the AC3 codec. strict -2 is required as a way that you acknowledge that the encoder is designated as experimental.
  • -strict -2 -c:a aac – Use the native FFmpeg AAC audio encoder.
  • -c:a copy – Stream copy the audio.
  • -map 0:a – Designate the audio stream(s) from the first input as a source for the output file.
  • -c:v copy – Stream copy the video.
  • -map 0:v – Designate the video stream(s) from the first input as a source for the output file.
  • -y – A global option to overwrite the output file if it already exists.
    • This works for me: ffmpeg -y -i Source.mkv -map 0:v -c:v copy -map 0:a -c:a copy -map 0:a -strict -2 -c:a aac out.mkv
