◆ run()

void DVBStreamHandler::run ( void )

overrideprivatevirtual

Runs the Qt event loop unless we have a QRunnable, in which case we run the runnable run instead.

Note: If you override this method you must call RunProlog before you do any work and RunEpilog before you exit the run method.

Reimplemented from MThread.

Definition at line 118 of file dvbstreamhandler.cpp.

◆ RunTS()

void DVBStreamHandler::RunTS ( void )

private

Uses TS filtering devices to read a DVB device for tables & data.

This supports all types of MPEG based stream data, but is extremely slow with DVB over USB 1.0 devices which for efficiency reasons buffer a stream until a full block transfer buffer full of the requested tables is available. This takes a very long time when you are just waiting for a PAT or PMT table, and the buffer is hundreds of packets in size.

Definition at line 142 of file dvbstreamhandler.cpp.

Referenced by run().

◆ RunSR()

void DVBStreamHandler::RunSR ( void )

private

Uses "Section" reader to read a DVB device for tables.

This currently only supports DVB streams, ATSC and the raw MPEG streams used by some cable and satelite providers is not supported.

◆ SupportsTSMonitoring()

bool DVBStreamHandler::SupportsTSMonitoring ( void )

private

Returns true if TS monitoring is supported.

NOTE: If you are using a DEC2000-t device you need to apply the patches provided by Peter Beutner for it, see http://www.gossamer-threads.com/lists/mythtv/dev/166172 These patches should make it in to Linux 2.6.15 or 2.6.16.
