Application interface for the PMT decoder and the PMT generator. New decoded PMT tables are sent by callback to the application.

Function Documentation

bool dvbpsi_pmt_attach	(	dvbpsi_t *	p_dvbpsi,
		uint16_t	i_program_number,
		dvbpsi_pmt_callback	pf_callback,
		void *	p_cb_data )

Creates and initialization of a PMT decoder and attaches it to dvbpsi_t handle.

Parameters

p_dvbpsi	handle
i_program_number	program number
pf_callback	function to call back on new PMT
p_cb_data	private data given in argument to the callback

Returns

true on success, false on failure

dvbpsi_pmt_delete()

void dvbpsi_pmt_delete

(

dvbpsi_pmt_t *
