- Windows XP DirectShow Sample -- VMRMix
- --------------------------------------
-
- Description: This application shows capabilities of the new
- video mixing renderer (VMR) that is the default video
- renderer in Windows XP. In particular, it demonstrates
- how to use the VMR in a mixing mode with several sources,
- how to apply a bitmap image with a color key over the video,
- and how to take advantage of the IVMRMixerControl interface
- to manage source and destination rectangles and alpha-level
- for each media stream.
-
- Usage:
- Upon initialization, VMRMix asks the user to specify a
- media folder that contains at least two valid media files,
- after which it loads media settings from that folder.
- The user is asked to specify playback options:
- number of source files, size of the playback window, and
- whether to display a static bitmap image. When the user
- clicks on the 'Play' button, a new window appears to mix
- the selected streams. The demonstration lasts until the
- longest media file reaches the end. You can interrupt the
- demonstration by closing the playback window.
-
- Troubleshooting:
- This application was originally created as a stress test,
- so it uses more system resources when displaying a maximum
- number of streams and when using "full-screen" mode. If
- video is freezing or slows down, try selecting fewer sources
- and turn off the "full-screen" option.
