virtual std::string TheoraDataSource::repr ( )

pure virtual

returns a string representation of the DataSource, eg 'File: source.ogg'

Implemented in TheoraMemoryFileDataSource, and TheoraFileDataSource.

virtual void TheoraDataSource::seek ( unsigned long  byte_index )

pure virtual

position the source pointer to byte_index from the start of the source

Implemented in TheoraMemoryFileDataSource, and TheoraFileDataSource.

virtual unsigned long TheoraDataSource::size ( )

pure virtual

return the size of the stream in bytes

Implemented in TheoraMemoryFileDataSource, and TheoraFileDataSource.

virtual unsigned long TheoraDataSource::tell ( )

pure virtual

return the current position of the source pointer

Implemented in TheoraMemoryFileDataSource, and TheoraFileDataSource.
