Detailed Description

Pre-loads the entire file and streams from memory. Very useful if you're continuously displaying a video and want to avoid disk reads. Not very practical for large files.

inline

int TheoraMemoryFileDataSource::read ( void *  output, int  nBytes  )

virtual

Reads nBytes bytes from data source and returns number of read bytes. if function returns less bytes then nBytes, the system assumes EOF is reached.

Implements TheoraDataSource.

std::string TheoraMemoryFileDataSource::repr ( )

inlinevirtual

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

Implements TheoraDataSource.

void TheoraMemoryFileDataSource::seek ( uint64_t  byte_index )

virtual

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

Implements TheoraDataSource.

uint64_t TheoraMemoryFileDataSource::size ( )

virtual

return the size of the stream in bytes

Implements TheoraDataSource.

uint64_t TheoraMemoryFileDataSource::tell ( )

virtual

return the current position of the source pointer

Implements TheoraDataSource.
