C++ (Cpp) create_tracks Examples

Example #1

File: hello.c Project: rayl/MLT

int main( int argc, char **argv )
{
	// Initialise the factory
	if ( mlt_factory_init( NULL ) == 0 )
	{
		// Create the default consumer
		mlt_consumer hello = mlt_factory_consumer( NULL, NULL );

		// Create a producer using the default normalising selecter
		mlt_producer world = create_tracks( argc, argv );

		// Connect the producer to the consumer
		mlt_consumer_connect( hello, mlt_producer_service( world ) );

		// Start the consumer
		mlt_consumer_start( hello );

		// Wait for the consumer to terminate
		while( !mlt_consumer_is_stopped( hello ) )
			sleep( 1 );

		// Close the consumer
		mlt_consumer_close( hello );

		// Close the producer
		mlt_producer_close( world );

		// Close the factory
		mlt_factory_close( );
	}
	else
	{
		// Report an error during initialisation
		fprintf( stderr, "Unable to locate factory modules\n" );
	}

	// End of program
