Benefits Over DirectShow
Media Foundation offers the following benefits:
- Is scalable for high-definition content and DRM-protected content.
- Allows DirectX Video Acceleration to be used outside of the DirectShow infrastructure. DXVA 2.0 is available to user-mode components without using the DirectShow video renderer.
- Provides better resilience to CPU, I/O, and memory stress for low-latency glitch-free playback of audio and video. Video tearing has been minimized. The improved video processing support also enables high color spaces and enhanced full-screen playback. Enhanced video renderer (EVR) which is also available for DirectShow, offers better timing support and improved video processing.
- Media Foundation extensibility enables different content protection systems to operate together.
- Media Foundation uses the Multimedia Class Scheduler Service (MMCSS), a new system service in Windows Vista, Windows 7 & Windows 8. MMCSS enables multimedia applications to ensure that their time-sensitive processing receives prioritized access to CPU resources.
