Study and Realization of ASF Dismemberment Technology

The advanced systems format(ASF) is the file format used by Windows media.Audio and/or Video content compressed with a wide variety of codes can be stored in an ASF file and played back with the Windows media player.But nowadays,Some ASF Video files contain many advertisements,some frames are illegible and it is hard to separate interesting content from other frames.So it is necessary to develop software which can edit ASF file effectively,enable interesting content played repeatedly.It can facilitate the development of the software by using reader object,writer object,editor object provided by WMF SDK,in spite of the details of ASF files.Points out the problems in the process of ASF file dismemberment.At the same time,dismemberment precision,decode/encode technology avoiding the writer object,properties revision are also studied.Finally software is developed which realized the dismemberment of ASF files.
