FFmpeg Plugin

Dynamically extract frames from videos by time or percentage. Includes basic blank frame avoidance. Based on ffmpeg.

Installation

  1. Add ImageResizer.Plugins.FFmpeg.dll to your project using Visual Studio.
  2. Add <add name="FFmpeg" downloadNativeDependencies="true" /> inside <resizer><plugins></plugins></resizer> in Web.config.
  3. During Application_Start, call ImageResizer.Configuration.Config.Current.Plugins.LoadPlugins() to ensure that ffmpeg is downloaded before the application starts accepting requests.

Use

http://example.com/videos/thisvideo.m4v?ffmpeg.seconds=45.3

  • ffmpeg.seconds=45.3 - Will grab the frame 45.3 seconds into the video file. Fastest way to grab an image.
  • ffmpeg.percent=50.1 - Will grab the frame 50.1 percent through the video file (slower, as the videos length must be queried)
  • ffmpeg.skipblankframes=true - Even slower - if the acquired frame is blank, another frame 5 seconds later will be chosen, and so on, up to 4 times.

This plugin (FFmpeg Plugin) is part of the Elite Edition
