Question

我已经将新列添加到微博中作为视频。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，我遇到了错误。（我试图以.MOV格式上传视频）

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

的Gemfile

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

微博模型

 mount_uploader :video, VideoUploader

我还在我的FFmpeg文件中进行了配置，并从FFmpeg下载文件。

将gem 'carrierwave-ffmpeg'添加到您的Gemfile中，并确保在计算机上通过homebrew安装ffmpeg和ffmpeg2theora。

使用carrierwave-video上传视频时出现错误：＆＃34;视频无法使用FFmpeg进行转码。＆＃34;
