Analysis

Overview

Video content connects an video resource to a frame

• Video content is a content of a frame representing video.
• Video resources are resources for video.
• Video resources have the same information as any other resources plus specific information about the video they are representing.
• Video content is responsible for returning the visual representation of the video
• There should be drag and drop support, so video can be dropped onto a frame and a video content is created automatically from them. Video are scaled if they are bigger than the frame they are dropped onto.
• There should be support for creating a frame with video content by choosing an video file.
• Video resources should support clipping (in point, out point), rate and volume

Task requirements

• Define basic video content.
• Define basic video resource.
• Define how content work with frames to find a renderer (is this a scene?)

Task result

The result of this task should be source code.

Implementation idea

• Create class VideoContent which is concrete implementation of org.sophie2.base.model.book.FrameContent for video.
• VideoContent should override mainResource() and return Prop<VideoResource>.
• Create class VideoResource which is concrete implementation of org.sophie2.base.model.book.resource.BookResource for video resources.
• VideoResource should have methods:
  • inPoint
  • outPoint
  • startPoint (0)
  • endPoint (same as duration)
  • rate
  • volume
  • duration
  • poster frame (time code for the frame to use when displaying the video as a still, defaults to 0)

• Video
  • Video is represented by an image, either the first frame of the video, or the poster frame
  • Video can have a controller
  • Determine if any of this should be part of the content, or kept elsewhere, ie does the content have any say in how the resource is represented on screen?
  • If yes, maybe contents should have extension points that keep the list of renderers for this content (and similar for images and audio, ie any content)

How to demo

• Create a frame with video resource.
• Check if the resource is set correctly and check if the information about the resource is correct.
• Try changing the resource and check again the same things.
