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
  

example (the ui design is fully customizable on the example)

• dependencies used:
  • helpers
  • image picker
  • gallery saver

crop video	rotate video

trim video	export video
