Member Function Documentation

void DTVRecorder::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 RecorderBase.

Reimplemented in MpegRecorder, NuppelVideoRecorder, and V4LRecorder.

Referenced by V4LRecorder::SetOption(), SetOption(), ImportRecorder::SetOptionsFromProfile(), and SetOptionsFromProfile().

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

handles the "wait_for_seqstart" option.

Reimplemented from RecorderBase.

Reimplemented in ASIRecorder, MpegRecorder, NuppelVideoRecorder, and V4LRecorder.

Definition at line 122 of file dtvrecorder.cpp.

void DTVRecorder::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.

Implements RecorderBase.

Reimplemented in ASIRecorder, FirewireRecorder, ImportRecorder, IPTVRecorder, MpegRecorder, and NuppelVideoRecorder.

Definition at line 130 of file dtvrecorder.cpp.

bool DTVRecorder::IsErrored ( void   )  [inline, virtual]

Tells us whether an unrecoverable error has been encountered.

long long DTVRecorder::GetFramesWritten ( void   )  [inline, 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.

Implements RecorderBase.

Reimplemented in NuppelVideoRecorder.

Definition at line 47 of file dtvrecorder.h.

Referenced by MpegRecorder::run().

void DTVRecorder::SetVideoFilters ( QString &  filters  )  [inline, 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.

Implements RecorderBase.

Reimplemented in MpegRecorder, and NuppelVideoRecorder.

Definition at line 49 of file dtvrecorder.h.

void DTVRecorder::Initialize ( void   )  [inline, virtual]

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

Implements RecorderBase.

Reimplemented in MpegRecorder, and NuppelVideoRecorder.

Definition at line 50 of file dtvrecorder.h.

int DTVRecorder::GetVideoFd ( void   )  [inline, 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.

Implements RecorderBase.

Reimplemented in MpegRecorder, and NuppelVideoRecorder.

Definition at line 51 of file dtvrecorder.h.

void DTVRecorder::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.

bool DTVRecorder::FindMPEG2Keyframes ( const TSPacket *  tspacket  )  [protected]

Locates the keyframes and saves them to the position map.

This searches for three magic integers in the stream. The picture start code 0x00000100, the GOP code 0x000001B8, and the sequence start code 0x000001B3. The GOP code is prefered, but is only required of MPEG1 streams, the sequence start code is a decent fallback for MPEG2 streams, and if all else fails we just look for the picture start codes and call every 16th frame a keyframe.

NOTE: This does not only find keyframes but also tracks the total frames as well. At least a couple times seeking has been broken by short-circuiting the search once a keyframe stream id has been found. This may work on some channels, but will break on others so algorithmic optimizations should be done with great care.
