ASFtoPIPE Description

The ASFtoPIPE application was designed to be a simple, open-source Windows utility that extracts audio and video streams from Windows Media ASF files, such as .WMV and .WMA files. Video streams are extracted as a continuous stream of PPM-format images. Audio streams are extracted as raw PCM samples. Both can then be written to named pipes, avoiding the need for gigantic files on disk. Key details such as the audio sample rate, video frame rate, audio sample size and number of audio channels are also available. Many open source tools exist to encode audio in video in a variety of formats. Unfortunately, these tools currently can't handle the latest Windows Media formats as input. This makes converting Windows Media 9 files to FLV (Flash Video) and other formats a pain. asftopipe uses the Microsoft Windows Media API to read the file, so it supports all current types of ASF (WMA and WMV) files. For instance, asftopipe has no trouble reding a video created by Windows Movie Maker. asftopipe also has convenient features that make implementation of progress displays and termination of a cancelled file conversion easier to accomplish without advanced win32 programming.
