Detailed Description
Video mixer. This class represents the frame store for the mixed video.
A user would typically create a derived class to override the MixVideo() or the StartMix()/NextMix() virtual functions for new screen patterns/algorithms.

Member Function Documentation
|
virtual |
Mixed data is now available. For a push model system, this is called with mixed data as returned by ReadMixed().
The "mixed" parameter is a reference to a pointer, so if the consumer wishes to take responsibility for deleting the pointer to an RTP data frame, then they can set it to NULL.
If false is returned then the push thread is exited.
Reimplemented from OpalBaseMixer.
|
virtual |
Set output video frame rate. May be dynamically changed at any time.
Reimplemented from OpalVideoMixer.
