  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • 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.

  • Executable 'ffmpeg' not found in python

    21 février 2021, par Ahmed Mohamed

    I'm trying to compress a video using python but there is an error that I can't understand how to solve it, so can you help me please ?
I have attached an image and the code enter image description here

    



    import ffmpy

input_name = input("Enter name of input file: ")
crf = int(input("Enter constant rate factor between 18 and 24: "))
output_name = input("Enter output file name: ")
inp = {input_name: None}
outp = {output_name: '-vcodec libx264 -crf %d'%crf}     #video  codec and compression rate
ff = ffmpy.FFmpeg(inputs=inp, outputs=outp)             #creates an FFmpeg object
print(ff.cmd)                                           #just to verify that it produces the correct ffmpeg command
ff.run()                                                #does the compression
print("done!")
