video_editor

Goal of this fork

• new trimmer style when the length of the video is greater than maxDuration
  • inside gesture scroll horizontally to change the maxDuration trim position in the video length
  • inside gesture update progress position and video seek position
  • see previous and next thumbnails out of the padding area
• video timeline along the trimmer
• new style of trimmer
• add possibility to select a frame of the video as the cover
  • choose between x frames exported from the trim selection
  • default select first frame by default and when trim values changed
  • display the selected frame when cover tab is opened
  • export cover as a file

Fix bugs

• avoid maxTrim to be smaller than minTrim
• avoid minTrim to be bigger than maxTrim
• synch transformation data with video or coverViever

New Features

• New supported actions
  • New trim (if video length > maxDuration param)
  • New widget to select a cover between x exported thumbnails from the trimmed period

New Trimmer	New Cover selection

Features

• Super flexible UI Design.
• Support actions:
  • Crop
  • Trim
  • Scale
  • Rotate

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
