  • How do you intentionally increase/decrease livestream quality using ffmpeg

    25 septembre 2022, par Evan Hassan

    You know those sport streaming websites ? Well I am trying to watch a game from one of those website... problem is I have awful wifi.

    


    I have access to the livestream video and I am trying to change the bitrate/fps to a higher quality for website embedding using ffmpeg. I understand for a video, this is more than possible, but how do you do this for a live stream ?

  • Extract just the audio link from a youtube video without converting

    19 janvier 2017, par kamron shaw

    I know there are hundreds of sites to convert youtube video to mp3. Most of them do it by first downloading the video and then converting it to mp3(or any other audio format) on their server using youtube-dl, ffmpeg or similar programs.

    What I want to know is, is there any way I can just extract the audio link for any youtube video ? I don’t know if it’s possible but I saw a couple of websites doing it .

    First Website : Openaisearch.com
    This website simply gives a download link for the audio(getting it from youtube videos). I searched for a song and saw the download url, it looked something like this :

    https://redirector.googlevideo.com/videoplayback?source=youtube&requiressl=yes&clen=3814013&upn=dzwY9aUVYME&lmt=1469875393441562&expire=1484854959&mime=audio%2Fmp4&nh=IgpwcjAxLnNlYTA5Kg01Mi45NS4yMTYuMTAy&itag=140...........

    I believe that this is not done by first downloading and converting the video to audio format(Correct me if I am wrong).
    Although the file which gets downloaded after using this link is without any extension, but adding ".m4a" at the end of downloaded file does the work.

    Second Website : http://keepvid.com/ ?url=https ://www.youtube.com/watch?v=PT2_F-1esPk

    Again similar website with similar audio link. You can check by visiting the URL and see link of audio files.

    Any idea how these websites get that "googlevideo.com" link ? Do they scrap the youtube video links or something ?

    Thanks.
