• Bash script to convert music from one directory into another

  26 octobre 2014, par SinTrans

  I’ve modified this script from the arch forums : https://wiki.archlinux.org/index.php/Convert_Flac_to_Mp3#With_FFmpeg

  I’m trying to find specific file types in a directory structure, convert them to another music file type, and place them in a "converted" directory that maintains the same directory structure.

  I’m stuck at stripping the string $b of its file name.

  $b holds the string ./converted/alt-j/2012\ an\ awesome\ wave/01\ Intro.flac

  Is there a way I can remove the file name from the string ? I don’t think ffmpeg can create/force parent directories of output files.

  #!/bin/bash
  
  # file convert script
  
  find -type f -name "*.flac" -print0 | while read -d $'\0' a; do
  
      b=${a/.\//.\/converted/}
  
      < /dev/null ffmpeg -i "$a" "${b[@]/%flac/ogg}"
  
      #echo "${b[@]/%flac/ogg}"

• Unknown Codec error at ffserver

  I installed ffmpeg following this page, https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

  As you see I enabled x264.
  But when I run ffserver, I get

  /etc/ffserver.conf:16: Unknown VideoCodec: libx264
  
  /etc/ffserver.conf:24: Unknown AudioCodec: libfaac

  My conf file is

• Compile FFmpeg with openssl for macOS

  23 juin 2017, par H. Wilson

  Hi I would like to ask how to compile ffmpeg with openssl for macOS.

  When I type https in ffmpeg to download / encode webstream from the website I always get an error

  "https protocol not found, recompile FFmpeg with openssl, guntls. or securetransport enabled"

  whilst http does work (some websites didn’t allow http as I got an error "HTTP error 403 Forbidden though)

  https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX

  I have read the link above but I am unsure about the process as I don’t use homebrew to install ffmpeg but built myself.

  I am the very beginner using ffmpeg and any help would be appreciated..
  I hope somebody could show me its process to compile ffmpeg with openssl.

  For further advice, I am wondering if the function of ffmpeg I built myself is same as the static one here : ttps ://ffmpeg.zeranoe.com/builds/

  I built ffmpeg for mac by this website : http://ericholsinger.com/install-ffmpeg-on-a-mac

  Thanks in advance
