[DirectShow] File Format and compression format

DirectShow is an open architecture. As long as the filter supports both analysis and decoding formats, msdn provides a summary.

Supported file formats:

Windows Media Audio (WMA )*

Windows Media video (WMV )*

Advanced Systems format (ASF )*

Motion Picture Experts Group (mPEG)

Audio-video interleaved (AVI)

QuickTime (version 2 and lower)

Wav

AIFF

ISO MPEG-4 video version 1.0 *

Microsoft MPEG-4 Version 3 *

Sipro labs ACELP *

MPEG audio layer-3 (mp3)

Digital video (DV)

MPEG-1

The representation with * must be supported using the Windows Medio format SDK, MPEG-1 and MP3 only support decompression, not MPEG-2.

In terms of concept, we have an accurate understanding of what is the file format and what is the compression technology.
