Member Function Documentation

◆ TeardownAll()

void MpegRecorder::TeardownAll ( void  )

Definition at line 73 of file mpegrecorder.cpp.

Referenced by ~MpegRecorder().

◆ SetOption() [1/2]

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

handles the "wait_for_seqstart" option.

Reimplemented from DTVRecorder.

Definition at line 110 of file mpegrecorder.cpp.

◆ SetOption() [2/2]

void MpegRecorder::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 183 of file mpegrecorder.cpp.

◆ SetVideoFilters()

void MpegRecorder::SetVideoFilters ( QString &  filters)
inlineoverridevirtual

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 25 of file mpegrecorder.h.

◆ SetOptionsFromProfile()

void MpegRecorder::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 274 of file mpegrecorder.cpp.

◆ Initialize()

void MpegRecorder::Initialize ( void  )
inlineoverridevirtual

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

Reimplemented from DTVRecorder.

Definition at line 32 of file mpegrecorder.h.

◆ run()

void MpegRecorder::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 909 of file mpegrecorder.cpp.

◆ Reset()

void MpegRecorder::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 1218 of file mpegrecorder.cpp.

◆ Pause()

void MpegRecorder::Pause ( bool  clear = true)
overridevirtual

Pause tells recorder to pause, it should not block.

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

Parameters
clearif true any generated timecodes should be reset.
See also
Unpause(), WaitForPause()

Reimplemented from RecorderBase.

Definition at line 1233 of file mpegrecorder.cpp.

◆ PauseAndWait()

bool MpegRecorder::PauseAndWait ( int  timeout = 100)
overridevirtual

If m_request_pause is true, sets pause and blocks up to timeout milliseconds or until unpaused, whichever is sooner.

This is the where we actually do the pausing. For most recorders that need to do something special on pause, this is the method to overide.

Parameters
timeoutnumber of milliseconds to wait defaults to 100.
Returns
true if recorder is paused.

Reimplemented from RecorderBase.

Definition at line 1241 of file mpegrecorder.cpp.

◆ IsRecording()

bool MpegRecorder::IsRecording ( void  )
inlineoverridevirtual

Tells whether the StartRecorder() loop is running.

Reimplemented from RecorderBase.

Definition at line 39 of file mpegrecorder.h.

◆ Open()

bool MpegRecorder::Open ( void  )

Definition at line 903 of file mpegrecorder.cpp.

◆ GetVideoFd()

int MpegRecorder::GetVideoFd ( void  )
inlineoverridevirtual

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 43 of file mpegrecorder.h.

◆ ProcessTSPacket()

bool MpegRecorder::ProcessTSPacket ( const TSPacket tspacket)
