v0.13.alpha

This Release implements a new Player API

Players are specialized Pipelines that simplify the processes of:

• testing/confirming camera connections and URIs
• rendering captured images and video recordings.

This is a "first release" and the API may require some iteration as more use cases are defined.

The following Issues were closed in this Release

Issues for new Client Services

• Implement new Image Source component #438
• Implement new File Source Component #436
• Implement new Player component #433
• Implement two new derived Player components - Video-Render-Player & Image-Render-Player #445
• Extend the Capture Frame/Image Actions to support Client Listeners #443
• [Feature Request] Customization of filename generated by capture frame/object action #351

Issues in support of the above

• Implement two new Pipeline base classes: PipelineStateMgr and PipelineXWinMgr #434
• Refactor PipelineBintr to use new PipelineStateMgr and PipelineXWinMgr base classes #435
• Refactor Pipeline Pause & Stop to use timer callback to change pipeline state. #430
• Implement RenderSinkBintr class as base class for Overlay and Window Sink #447
• Derive Decode and Image Sources from a new ResourceSourceBintr virtual class #450
