视频仍在使用redis和sidekiq对Rails应用程序中的消息进行编码

Question

我是rails的新手。我正在精确地执行(复制粘贴)

https://www.pubnub.com/blog/2015-12-08-building-video-sharing-app-server-messaging-ruby/

最重要的是，我正在运行

 redis -server

和

bundle exec sidekiq

但是我收到消息"Video is still being encoded."，我检查了数据库，我的视频正在被插入。这是Redis和sidekiq的日志

Redis-- $ redis-server

下面是sidekiq日志

Answer 1

sidekiq 4.2.2 VideoShrimp [0 of 25 busy]: No such file or directory - ffmpeg -您的系统上没有安装ffmpeg，或者PATH中没有可执行文件。

安装/home/ubuntu应该会有帮助，你可以在ubuntu上这样做：sudo apt-get install ffmpeg (我假设你是因为/home/ubuntu才在ubuntu上的)。

[64544] 11 Oct 07:36:14.427 # Creating Server TCP listening socket *:6379: bind: Address already in use指示套接字已在使用中，因此您可能已有redis服务器在运行。
