• recompiling audio from a movie source

  4 novembre 2016, par jkushner

  Is it possible to recompile movie files to re-stream the audio so they all have the same volume level ? We’ve got users submitting videos and to me it seems some are higher in volume whereas others are not, and they all have the same volume level on the controls, and i’d like to standardize this so all movie files have the same volume levels.

  I was thinking of ffmpeg although I only have novice knowledge of this technology and haven’t done my research in it yet.

  Anyway if there’s anything available I’d love to know.

  Thanks !

• how to use ffmpeg -cookies to download aes encrypted hls stream

  3 mars 2014, par Shuman

  i need this cookies, so i can download stream from a m3u8 file,(it has this line

  #EXT-X-KEY:METHOD=AES-128,URI="https://xxx/myStream.php?wowzasessionid=861683502"

  so i can get the key right ? ( i have the login credential cookies to that site )

  according to this discussion, it was there, and i checked the code on github, it has the option.

  but when i compile it with the default options, there is no cookies option. how do i turn it on ?
