Member Function Documentation

void NuppelVideoRecorder::SetOption	(	const QString &	name,
		int	value
	)		`[virtual]`

handles the "wait_for_seqstart" option.

Reimplemented from V4LRecorder.

Definition at line 266 of file NuppelVideoRecorder.cpp.

Referenced by SetOption(), SetOptionsFromProfile(), and Transcode::TranscodeFile().

void NuppelVideoRecorder::SetOption	(	const QString &	opt,
		const QString &	value
	)		`[virtual]`

Set an specific option.

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

Reimplemented from V4LRecorder.

Definition at line 349 of file NuppelVideoRecorder.cpp.

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

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 354 of file NuppelVideoRecorder.cpp.

void NuppelVideoRecorder::Initialize ( void ) [virtual]

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

Reimplemented from DTVRecorder.

Definition at line 694 of file NuppelVideoRecorder.cpp.

void NuppelVideoRecorder::run ( void ) [virtual]

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

See also:: StopRecording()

Implements RecorderBase.

Definition at line 1049 of file NuppelVideoRecorder.cpp.

void NuppelVideoRecorder::Pause ( bool clear = true ) [virtual]

Pause tells recorder to pause, it should not block.

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

Parameters:

clear if true any generated timecodes should be reset.

See also:: Unpause(), WaitForPause()

Reimplemented from RecorderBase.

Definition at line 455 of file NuppelVideoRecorder.cpp.

bool NuppelVideoRecorder::IsPaused ( bool holding_lock = false ) const [virtual]

Returns true iff recorder is paused.

Reimplemented from RecorderBase.

Definition at line 467 of file NuppelVideoRecorder.cpp.

Referenced by doAudioThread(), DoMJPEG(), DoV4L1(), DoV4L2(), and doWriteThread().

bool NuppelVideoRecorder::IsRecording ( void ) [virtual]

Tells whether the StartRecorder() loop is running.

Reimplemented from RecorderBase.

Definition at line 483 of file NuppelVideoRecorder.cpp.

long long NuppelVideoRecorder::GetFramesWritten ( void ) [virtual]

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 488 of file NuppelVideoRecorder.cpp.

bool NuppelVideoRecorder::Open ( void )

Definition at line 987 of file NuppelVideoRecorder.cpp.

Referenced by run().

int NuppelVideoRecorder::GetVideoFd ( void ) [virtual]

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 493 of file NuppelVideoRecorder.cpp.

void NuppelVideoRecorder::Reset ( void ) [virtual]

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 2318 of file NuppelVideoRecorder.cpp.

void NuppelVideoRecorder::SetVideoFilters ( QString & filters ) [virtual]

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 477 of file NuppelVideoRecorder.cpp.

void NuppelVideoRecorder::SetTranscoding ( bool value ) [inline]

Definition at line 102 of file NuppelVideoRecorder.h.

Referenced by Transcode::TranscodeFile().

void NuppelVideoRecorder::SetNextRecording	(	const ProgramInfo *	,
		RingBuffer *
	)		`[virtual]`

Sets next recording info, to be applied as soon as practical.

This should not lose any frames on the switchover, and should initialize the RingBuffer stream with headers as appropriate.

The switch does not have to happen immediately, but should happen soon. (i.e. it can wait for a key frame..)

This calls TVRec::RingBufferChanged() when the switch happens.

Reimplemented from DTVRecorder.

Definition at line 2809 of file NuppelVideoRecorder.cpp.

void NuppelVideoRecorder::ResetForNewFile ( void ) [virtual]

Reimplemented from DTVRecorder.

Definition at line 2826 of file NuppelVideoRecorder.cpp.

Referenced by Reset().

void NuppelVideoRecorder::FinishRecording ( void ) [virtual]

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

Reimplemented from DTVRecorder.

Referenced by DoMJPEG(), DoV4L1(), and DoV4L2().
