Member Function Documentation

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

handles the "wait_for_seqstart" and "pkt_buf_size" options.

Reimplemented from DTVRecorder.

Definition at line 148 of file dvbrecorder.cpp.

Referenced by SetOptionsFromProfile().

void DVBRecorder::SetOptionsFromProfile ( RecordingProfile *  profile,
const QString &  videodev,
const QString &  audiodev,
