    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • I can no longer convert an mp4 video that is downloaded from YouTube to .wav file using ffmpeg [closed]

    25 juillet 2024, par user3288051

    I can no longer convert an mp4 video that is downloaded from YouTube to .wav file using ffmpeg.

    


    Here is the command I am using :

    


    video_name = "my_video_file"
dir_name = "experiment/john_doe/"

command = f'ffmpeg -i {dir_name}{video_name}.mp4 -ab 160k -ar 44100 -vn {dir_name}{video_name}.wav'

try:
    subprocess.check_call(command, shell=True)
except Exception as ex:
    print("Error: " + str(ex))


    


    Unfortunately, I get the following error :

    


    


    Output #0, wav, to 'experiment/john_doe/my_video_file.wav' : [out#0/wav
@ 0x1526131c0] Output file does not contain any stream Error opening
output file experiment/john_doe/James_Murphy2.wav. Error opening
output files : Invalid argument Error : Command 'ffmpeg -i
experiment/john_doe/my_video_file.mp4 -ab 192k -ac 2
experiment/john_doe/my_video_file.wav' returned non-zero exit status
234.

    


    


    Did YouTube change its codec ?

    


    Here is my video file in case you would like to give it a try. I downloaded it from my own YouTube channel (my own video).

    


    I would appreciate your help.

    


  • FFMPEG Subtitle Burning - Make Them Look Like Youtube Captions

    21 septembre 2016, par Spencer

    I want to burn subtitles into videos and make them look as close to the YouTube captions as possible. I’ve gotten pretty close with the following :

    ffmpeg -i VIDEOFILE.mkv -vf subtitles="f=SUBSFILE.vtt:force_style='FontName=Arial,FontSize=14,OutlineColour=&H55000000,BorderStyle=3,WrapStyle=2'" -y ENCODED-WITH-SUBS.mp4

    1. The major thing I want to fix in the above command is that when there are multiple lines, the backgrounds overlap.

    enter image description here

    If you look at captions on YouTube there is always a nice small amount of space between the backgrounds.

    enter image description here

    2. The second thing I’d like to do is make the corners of the backgrounds rounded if possible.

    I’ve looked through the documentation but I’m hoping I missed something. Thanks for any suggestions !
