Installation (More info on Flutter FFMPEG)

Android

Add on android/build.gradle file and define package name in ext.flutterFFmpegPackage variable.

ext.flutterFFmpegPackage = "min-gpl-lts"

iOS

(Flutter >= 1.20.x)

  • Edit ios/Podfile, add the following block before target 'Runner do and specify the package name in min-gpl-lts section:

      # "fork" of method flutter_install_ios_plugin_pods (in fluttertools podhelpers.rb) to get lts version of ffmpeg
  def flutter_install_ios_plugin_pods(ios_application_path = nil)
   # defined_in_file is set by CocoaPods and is a Pathname to the Podfile.
    ios_application_path ||= File.dirname(defined_in_file.realpath) if self.respond_to?(:defined_in_file)
    raise 'Could not find iOS application path' unless ios_application_path

    # Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
    # referring to absolute paths on developers' machines.

    symlink_dir = File.expand_path('.symlinks', ios_application_path)
    system('rm', '-rf', symlink_dir) # Avoid the complication of dependencies like FileUtils.

    symlink_plugins_dir = File.expand_path('plugins', symlink_dir)
    system('mkdir', '-p', symlink_plugins_dir)

    plugins_file = File.join(ios_application_path, '..', '.flutter-plugins-dependencies')
    plugin_pods = flutter_parse_plugins_file(plugins_file)
    plugin_pods.each do |plugin_hash|
      plugin_name = plugin_hash['name']
      plugin_path = plugin_hash['path']

      if (plugin_name && plugin_path)
          symlink = File.join(symlink_plugins_dir, plugin_name)
          File.symlink(plugin_path, symlink)

          if plugin_name == 'flutter_ffmpeg'
              pod plugin_name + '/min-gpl-lts', :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
          else
              pod plugin_name, :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
          end
      end
    end
  end

  • Ensure that flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__)) function is called within
    target 'Runner' do block. In that case, it is mandatory that the added function is named
    flutter_install_ios_plugin_pods and that you do not make an explicit call within that block.

(Flutter < 1.20.x)

  • Edit ios/Podfile file and modify the default # Plugin Pods block as follows. Do not forget to specify the package
    name in min-gpl-lts section.

      # Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
  # referring to absolute paths on developers' machines.
  system('rm -rf .symlinks')
  system('mkdir -p .symlinks/plugins')
  plugin_pods = parse_KV_file('../.flutter-plugins')
  plugin_pods.each do |name, path|
      symlink = File.join('.symlinks', 'plugins', name)
      File.symlink(path, symlink)
      if name == 'flutter_ffmpeg'
          pod name+'/min-gpl-lts', :path => File.join(symlink, 'ios')
      else
          pod name, :path => File.join(symlink, 'ios')
      end
  end
