Detailed Description

This is the coordinating class of the Recorder Subsystem.

TVRec is used by EncoderLink, which in turn is used by RemoteEncoder which allows the TV class on the frontend to communicate with TVRec and is used by MainServer to implement portions of the MythTV Network Protocol on the backend.

TVRec contains an instance of RecorderBase, which actually handles the recording of a program. It also contains an instance of RingBuffer, which in this case is used to either stream an existing recording to the frontend, or to save a stream from the RecorderBase to disk. Finally, if there is a tuner on the hardware RecorderBase is implementing then TVRec contains a channel instance for that hardware, and possibly a SignalMonitor instance which monitors the signal quality on a tuners current input.

Member Function Documentation

◆ Init()

bool TVRec::Init ( void )

◆ RecordPending()

void TVRec::RecordPending	(	const ProgramInfo *	rcinfo,

◆ SetChannel()

void TVRec::SetChannel	(	const QString &	name,
		uint	requestType = `kFlagDetect`
	)

Changes to a named channel on the current tuner.

You must call PauseRecorder() before calling this.

Parameters

name	channum of channel to change to
requestType	tells us what kind of request to actually send to the tuning thread, kFlagDetect is usually sufficient

◆ QueueEITChannelChange()

bool TVRec::QueueEITChannelChange ( const QString & name )

Queues up a channel change for the EITScanner.

Unlike the normal SetChannel() this does not block until the channel change occurs to avoid a deadlock if EITScanner::StopActiveScan() is called with the stateChangeLock held while the EITScanner is calling TVRec::SetChannel().

Parameters

rate	The update rate to use in milliseconds, use 0 to disable signal monitoring.
notifyFrontend	If 1, SIGNAL messages will be sent to the frontend using this recorder.

◆ CheckChannelPrefix()

bool TVRec::CheckChannelPrefix	(	const QString &	prefix,
		uint &	complete_valid_channel_on_rec,
		bool &	is_extra_char_useful,
		QString &	needed_spacer
	)		const

Checks a prefix against the channels in the DB.

If the prefix matches a channel on any recorder this function returns true, otherwise it returns false.

If the prefix matches any channel entirely (i.e. prefix == channum), then the inputid of the recorder it matches is returned in 'complete_valid_channel_on_rec'; if it matches multiple recorders, and one of them is this recorder, this recorder is returned in 'complete_valid_channel_on_rec'; if it isn't complete for any channel on any recorder 'complete_valid_channel_on_rec' is set to zero.

If adding another character could reduce the number of channels the prefix matches 'is_extra_char_useful' is set to true, otherwise it is set to false.

Finally, if in order for the prefix to match a channel, a spacer needs to be added, the first matching spacer is returned in needed_spacer. If there is more than one spacer that might be employed and one of them is used for the current recorder, and others are used for other recorders, then the one for the current recorder is returned. The spacer must be inserted before the last character of the prefix for anything else returned from the function to be valid.

Returns: true if this is a valid prefix for a channel, false otherwise
