Detailed Description
This node implements an publish-subsribers pattern to pass the video to any number of registered consumers.The node can be used to integrate an OpenVideo sink into another programm.
Supported Pixel Formats:
- : R8G8B8
- : B8G8R8
- : R8G8B8X8
- : B8G8R8X8
- : L8

Member Function Documentation
|
|
Is called once before the (process)traversal starts. Init should be used to implement any initializations a specific node needs. Reimplemented from openvideo::Node. Definition at line 78 of file VideoSink.cxx. References openvideo::Node::inputs, isStarted, and openvideo::Node::state. |
|
|
return value = the number of supported input formats. the formats are stored in 'pixelFormats'. Implements openvideo::Node. Definition at line 56 of file VideoSink.cxx. References openvideo::FORMAT_B8G8R8, openvideo::FORMAT_B8G8R8X8, openvideo::FORMAT_L8, openvideo::FORMAT_R5G6B5, openvideo::FORMAT_R8G8B8, openvideo::FORMAT_R8G8B8X8, and openvideo::Node::pixelFormats. |
|
|
This function is called after OpenVideo's graph is entirely traversed and before a new traversal is invoked. Here, a specific node implementation can reset some data before a new traversal will take place. Reimplemented from openvideo::Node. Definition at line 97 of file VideoSink.cxx. |
|
|
This is the actual traversal fucntion. Process is called whenever a new traversal is invoked by the managers timer. A specific node implementation should do all its computations which need to be updated here. Reimplemented from openvideo::Node. Definition at line 88 of file VideoSink.cxx. References size_subscribers, openvideo::Node::state, and subsrcibers. |
