dvbcut可以从接收的dvb-c的数据流中截取感兴趣的一段，并保存成mpeg形式的输出文件。-dvbcut is a Qt application which enables you to select certain parts of an

MPEG transport stream (as received on Digital Video Broadcasting, DVB) and

save these parts into a single MPEG output file. It follows a "keyhole

surgery" approach. Thus, the input video and audio data is mostly kept

unchanged, only very few frames at the beginning and/or end of the selected

range are recoded in order to obtain a valid MPEG file.
