* @brief Uses the ogg and theora libraries to write video
|
||
|
|
* files.
|
||
|
|
*
|
||
|
|
* vtkOggTheoraWriter is an adapter that allows VTK to use the ogg and theora
|
||
|
|
* libraries to write movie files. This class creates .ogv files containing
|
||
|
|
* theora encoded video without audio.
|
||
|
|
*
|
||
|
|
* This implementation is based on vtkFFMPEGWriter and uses some code derived
|
||
|
|
* from the encoder example distributed with libtheora.
