When video acceleration is in use and if logging is enabled, video acceleration status messages and performance statistics are logged in the following files:

Video acceleration logging is disabled by default.

Steps

The video acceleration status messages identify the rendering mechanism used to display the video content on the client. The video acceleration status messages have the following format:

Display display-id Video port Id video-port-id stream Id stream-id status-message

Here is an example of a status message:

Display :3.0 Video port Id 91 stream Id 3 Compressed: H.264

You can use the Video port Id and stream Id values to find the corresponding performance statistics for the video stream, as described in Section 18.5.5.3, “Video Acceleration Performance Statistics”.

In a multihead configuration, Display indicates the head on which the video is being played. For example, Display :3.1 and Display :3.2. And, each head's Video port Id is in a different range.

Table 18.6, “Video Acceleration Status Messages” provides the list of the video acceleration status messages.

If Adobe Flash acceleration has occurred (indicated by the video acceleration icon), but there are no status messages in the log file, then the Adobe Flash content was decompressed on the Sun Ray server and displayed through the X11 API.

In addition to the general status messages logged for video acceleration, performance statistics for each video stream are logged at approximately one second intervals. The performance statistics can quickly increase the size of the log file by approximately 100 bytes for each second a video runs (or more for larger videos).

Here is an example output of the performance statistics:

The column titles in the output are as follows:

When video acceleration is active, a video acceleration taskbar icon is displayed in the Windows desktop taskbar. It is displayed on Windows XP and Windows Server 2003 with multimedia redirection enabled and on all Windows platforms with Adobe Flash acceleration enabled. Hovering the mouse over the icon displays the type of acceleration, the media type, and size, as shown in the following screenshots.

Figure 18.3. Verifying Video Acceleration is Active (Multimedia Redirection)

Figure 18.4. Verifying Video Acceleration is Active (Adobe Flash Acceleration)

Check the following:

If the video acceleration play icon tool tip shows Audio:NONE instead of Audio:PCM, the audio device for the Windows Media Player is not configured properly.

Workaround

Delete the following Windows registry key to revert back to the default audio device for the Windows Media Player:

HKEY_CURRENT_USER/Software/Microsoft/MediaPlayer/Preferences/DefaultAudioDevice

If a Windows connector session is relaunched or hotdesked while a supported media format clip is playing, a Windows Media Player error alert box might be displayed, as shown in Figure 18.5, “Windows Media Player Error During Session Reconnection”.

Figure 18.5. Windows Media Player Error During Session Reconnection

Workaround

Restart Windows Media Player and replay the video.

By default, multimedia redirection is enabled when using the uttsc command. The standard RDP protocol is used for video and audio when the multimedia redirection feature is disabled.

By default, Adobe Flash acceleration is enabled when using the uttsc command. The standard RDP protocol is used for Adobe Flash content when the Adobe Flash acceleration feature is disabled.
