Generates MPEG output, frame by frame.
This class generates MPEG output, frame by frame.
See the parent class SoMPEGRenderer for methods to specify the file and recording parameters.

Constructor.
|

Destructor.
| void SoMPEGFrameRenderer::recordFrame | ( | float | duration = 0 | ) |
Adds a new frame to the current MPEG output.
The duration (specified in seconds) is used to determine how many times this frame must be played in the MPEG output depending on the current number of frames per second (as specified by the method SoMPEGRenderer::setNumFramesPerSecond()).
