Member Function Documentation

◆ SetOption() [1/2]

void NuppelVideoRecorder::SetOption	(	const QString &	name,
		int	value
	)

overridevirtual

handles the "wait_for_seqstart" option.

Reimplemented from DTVRecorder.

Definition at line 162 of file NuppelVideoRecorder.cpp.

Referenced by SetOptionsFromProfile().

◆ SetOption() [2/2]

void NuppelVideoRecorder::SetOption	(	const QString &	name,
		const QString &	value
	)

overridevirtual

Set an specific option.

Base options include: codec, videodevice, tvformat (ntsc,ntsc-jp,pal-m), vbiformat ("none","pal teletext","ntsc").

Reimplemented from DTVRecorder.

Definition at line 245 of file NuppelVideoRecorder.cpp.

◆ SetOptionsFromProfile()

void NuppelVideoRecorder::SetOptionsFromProfile	(	RecordingProfile *	profile,
		const QString &	videodev,
		const QString &	audiodev,
		const QString &	vbidev
	)

overridevirtual

Sets basic recorder options.

SetOptionsFromProfile is used to tell the recorder about the recording profile as well as the devices to use.

Reimplemented from DTVRecorder.

Definition at line 250 of file NuppelVideoRecorder.cpp.

◆ Initialize()

void NuppelVideoRecorder::Initialize ( void )

overridevirtual

This is called between SetOptionsFromProfile() and run() to initialize any devices, etc.

Reimplemented from DTVRecorder.

Definition at line 573 of file NuppelVideoRecorder.cpp.

◆ run()

void NuppelVideoRecorder::run ( void )

overridevirtual

run() starts the recording process, and does not exit until the recording is complete.

See also: StopRecording()

Implements RecorderBase.

Definition at line 850 of file NuppelVideoRecorder.cpp.

◆ Pause()

void NuppelVideoRecorder::Pause ( bool clear = true )

overridevirtual

Pause tells recorder to pause, it should not block.

Once paused the recorder calls m_tvrec->RecorderPaused().

Parameters

clear if true any generated timecodes should be reset.

See also: Unpause(), WaitForPause()

Reimplemented from RecorderBase.

Definition at line 351 of file NuppelVideoRecorder.cpp.

◆ IsPaused()

bool NuppelVideoRecorder::IsPaused ( bool holding_lock = false ) const

overridevirtual

Returns true iff recorder is paused.

Reimplemented from RecorderBase.

Definition at line 363 of file NuppelVideoRecorder.cpp.

Referenced by doAudioThread(), DoV4L2(), and doWriteThread().

◆ IsRecording()

bool NuppelVideoRecorder::IsRecording ( void )

overridevirtual

Tells whether the StartRecorder() loop is running.

Reimplemented from RecorderBase.

Definition at line 377 of file NuppelVideoRecorder.cpp.

◆ GetFramesWritten()

long long NuppelVideoRecorder::GetFramesWritten ( void )

overridevirtual

Returns number of frames written to disk.

It is not always safe to seek up to this frame in a player because frames may not be written in display order.

Reimplemented from DTVRecorder.

Definition at line 382 of file NuppelVideoRecorder.cpp.

◆ Open()

bool NuppelVideoRecorder::Open ( void )

Definition at line 789 of file NuppelVideoRecorder.cpp.

Referenced by run().

◆ GetVideoFd()

int NuppelVideoRecorder::GetVideoFd ( void )

overridevirtual

Returns file descriptor of recorder device.

This is used by channel when only one open file descriptor is allowed on a device node. This is the case with video4linux devices and similar devices in BSD. It is not needed by newer drivers, such as those used for DVB.

Reimplemented from DTVRecorder.

Definition at line 387 of file NuppelVideoRecorder.cpp.

◆ Reset()

void NuppelVideoRecorder::Reset ( void )

overridevirtual

Reset the recorder to the startup state.

This is used after Pause(bool), WaitForPause() and after the RingBuffer's StopReads() method has been called.

Reimplemented from DTVRecorder.

Definition at line 1756 of file NuppelVideoRecorder.cpp.

◆ SetVideoFilters()

void NuppelVideoRecorder::SetVideoFilters ( QString & filters )

overridevirtual

Tells recorder which filters to use.

These filters are used by frame grabber encoders to lower the bitrate while keeping quality good. They must execute quickly so that frames are not lost by the recorder.

Reimplemented from DTVRecorder.

Definition at line 373 of file NuppelVideoRecorder.cpp.

◆ FinishRecording()

void NuppelVideoRecorder::FinishRecording ( void )

overridevirtual

Flushes the ringbuffer, and if this is not a live LiveTV recording saves the position map and filesize.

Reimplemented from DTVRecorder.

Definition at line 2260 of file NuppelVideoRecorder.cpp.

Referenced by DoV4L2().

◆ StartNewFile()
