For more information, see EVR Media Type Negotiation. The available substream formats might depend on the format of the reference stream. Substreams: Progressive YUV with per-pixel-alpha, such as AYUV or AI44.Reference stream: Progressive or interlaced YUV with no per-pixel alpha (such as NV12 or YUY2) or progressive RGB.The graphics driver determines which video formats are supported, but typically they are limited to the following: The application can change the z-order of the substreams, but no substream can be first in the z-order. Any additional streams are called substreams, and are mixed on top of the reference stream. The reference stream always appears first in the z-order. The first input stream is called the reference stream. The EVR filter, for DirectShow applications.īoth versions use the same internal objects to render video, and they share many of the same interfaces.The EVR media sink, for Media Foundation applications.The enhanced video renderer (EVR) is a component that displays video on the user's monitor.
