  • Download ONLY audio from a youtube video

    30 avril 2017, par Feras

    I know that there are a million ways to download a video from youtube and then convert it to audio or do further processing on it. But recently I was surprised to see an app called YoutubeToMp3 on mac actually showing "Skipping X mb of video" and supposedly only downloading the audio from the video, without the need to use bandwith to download the entire video and then convert it. I was wondering if this is actually correct and possible at all because I cant find any way to do that. Do you have any ideas ?

    EDIT :
    After some tests here is some additional information on the topic. The video which I tried to get the audio from is just a sample mp4 file from the internet :

    http://download.wavetlan.com/SVV/Media/HTTP/MP4/ConvertedFiles/MediaCoder/MediaCoder_test6_1m9s_XVID_VBR_306kbps_320x240_25fps_MPEG1Layer3_CBR_320kbps_Stereo_44100Hz.mp4

    I tried

    ffmpeg -i "input" out.mp3

    ffmpeg -i "input" -vn out.mp3

    ffmpeg -i “input” -vn -ac 2 -ar 44100 -ab 320k -f mp3 output.mp3

    ffmpeg -i “input” -vn -acodec copy output.mp3

    Unfortunately non of these commands seems to be using less bandwith. They all download the entire video. Now that you have the video can you confirm if there is actually a command that downloads only the audio stream from it and lowers the bandwith usage ? Thanks !
