• download youtube video as audio file, with URL in filename, to a specific output directory

  9 octobre 2018, par thanks_in_advance

  I do this to download a video as an audio file (mp3), with the video’s youtube URL (URI actually) in the audio file’s filename (I like having the URI in the filename because it helps me identify which video I grabbed the audio from) :

  youtube-dl --extract-audio --audio-format mp3 --prefer-ffmpeg --ffmpeg-location "C:\FFMPEG" "https://www.youtube.com/watch?v=k1-TrAvp_xs" --audio-quality 0

  The con with this approach : with this command, the file downloads to the same directory that contains youtube-dl.exe

  I do this to download a youtube video as an audio file (mp3) to a specific output directory :

  youtube-dl -o "C:\Documents\Downloads\%(title)s.%(ext)s" --extract-audio --audio-format mp3 --prefer-ffmpeg --ffmpeg-location "C:\FFMPEG" "https://www.youtube.com/watch?v=k1-TrAvp_xs" --audio-quality 0

  The con with this approach : with this command, the downloaded audio file’s filename doesn’t contain the youtube video’s URI.

  My Question : How can I combine the above 2 commands such that the downloaded audio file doesn’t have either of the cons mentioned above ?

• Create an image in PHP and turn it into a 10-second video [on hold]

  17 septembre 2019, par Emil A.

  I remember being able to create an image in PHP with custom text and background etc, then output it (or save) as a JPG/PNG etc. I want to do this but output this 1 frame as a 10-second MP4-video. How can I achieve this ?

  (Note : The end-result will show an unique and dynamical URL for cases where someone tries to watch the video without permission ; think hotlink-prevention for video.)

• 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.
