Recently I published a video blog post about RAVE (Remote Audio & Video Extensions), the technology behind SpeedScreen Multimedia Acceleration. RAVE supports high quality playback of media streams that can be decoded by a media player that uses DirectShow or DirectX Media Objects (DMO). A question came in from the field asking how a customer can determine whether SpeedScreen Multimedia Acceleration is functioning. So here are some handy tips for verifying whether RAVE is working or not. In addition, you’ll find a helpful troubleshooting article in our Knowledge Center.
The quick answer is that you can probably tell by the quality of the video playback since RAVE delivers a user experience on par with running the media player locally. But here are some other telltales. When RAVE is working, a black rectangle will quickly flash by as the video begins to play. Server CPU usage will be much lower than if the video were being rendered on the server (for comparison, you can disable SpeedScreen Multimedia Acceleration on the console and try playing the same video). Searching for “FilterInt” in ProcessExplorer will show that DLL loaded by the media player’s process.
Are there any enhancements that you would like to see to make it easier to discover that an additional codec needs to be installed on the client (or even on the server to support server-side rendering as a fallback)? For example, one possible enhancement would be for SpeedScreen Multimedia Acceleration to record RAVE events in the Windows Event Log.
