Detailed Description

ImportRecorder imports files, creating a seek map and other stuff that MythTV likes to have for recording.

Note
This currently only supports MPEG-TS files, but the plan is to support all files that ffmpeg does.

Member Function Documentation

◆ SetOptionsFromProfile()

void ImportRecorder::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 48 of file importrecorder.cpp.

◆ run()

void ImportRecorder::run ( void  )
overridevirtual

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

StopRecording()

Implements RecorderBase.

◆ Open()

bool ImportRecorder::Open ( void  )

Definition at line 156 of file importrecorder.cpp.

◆ Close()

void ImportRecorder::Close ( void  )

◆ InitStreamData()

void ImportRecorder::InitStreamData ( void  )
inlineoverridevirtual

Reimplemented from DTVRecorder.

Definition at line 40 of file importrecorder.h.

◆ GetFramesWritten()

long long ImportRecorder::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 87 of file importrecorder.cpp.

◆ GetRecordingQuality()

RecordingQuality* ImportRecorder::GetRecordingQuality ( const RecordingInfo ri) const
inlineoverridevirtual

Returns a report about the current recordings quality.

Reimplemented from DTVRecorder.
