• How to use multiple cookies in FFmpeg ?

  17 mai 2023, par カルロサグ

  I am trying to use cookies in ffmpeg to download a video that requires cookies

  


  I checked the documentation for multiple cookies using the "-cookies" argument, they must be separated by a newline, but the docs don't show an example of how to do it, there is only an example for the cookies syntax using a single cookie. I've tried "\n" and "\r\n" (used by the "-headers" argument) and they didn't work : I get a 403 response error

  


  Using a regular HTTP client such as curl or aiohttp (python) downloads the video, so the cookies and headers I provided are correct

  


  First test : Cookies as headers

• FFMPEG split mp3 and add metatag [closed]

  4 mai 2023, par Ghile

  I have a 2 hour mp3 that I automatically split with python3 and ffmpeg into many mp3 files. I would also like to add metadata to mp3 files, in order to have title, artist, year and album.

  


  In a csv file I have the cutting times and the name of the mp3 file, but I can't add meta data. The function I use is this :

  


  ffmpeg -loglevel panic -i 1.mp3 -ss 02:29:11 -to 02:34:43 -c copy -metadata 'title=My Title', 'artist=ME', 'date=2023' temp/myfile1.mp3


  


  Not work, It only works if I set the title only. Can you help me, please ?
Thank you,
