【问题描述】：

我已经在微博中添加了新专栏作为视频。现在我想使用carrierwave-video gem (https://github.com/rheaton/carrierwave-video)。现在，当我尝试上传视频时出现错误。（我尝试上传.MOV格式的视频）

错误

Video Failed to transcode with FFmpeg. Check ffmpeg install and verify video is not corrupt or cut short. Original error: undefined method `set_success' for #<Micropost:0x007fbf0d40dd68>

video_uploader.rb

class VideoUploader < CarrierWave::Uploader::Base
  include CarrierWave::Video

  process encode_video: [:mp4, callbacks: { after_transcode: :set_success } ]
  storage :file

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
end

宝石文件

 gem 'carrierwave',             '0.10.0'
 gem 'carrierwave-video'

微博模型

 mount_uploader :video, VideoUploader

我还通过从 FFmpeg 下载的文件在我的 FFmpeg 文件中进行了配置。
