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()
|
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 49 of file importrecorder.cpp.
◆ run()
|
overridevirtual |
run() starts the recording process, and does not exit until the recording is complete.
- See also
- StopRecording()
Implements RecorderBase.

◆ GetFramesWritten()
|
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 84 of file importrecorder.cpp.
◆ GetRecordingQuality()
