MJPEG Decompressor Filter
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
This filter decodes a video stream from motion JPEG to uncompressed video. Some digital video cameras produce a motion JPEG video stream.

Remarks
This filter is compatible with motion JPEG video that uses the FOURCC code 'MJPG'. It cannot decode other varieties of motion JPEG. For these, you will need to use a third-party decoder filter.
