Adobe Flash Player ActiveX Control Registry Settings (Compact 7)

3/12/2014

You can configure the Adobe Flash Player ActiveX control by using this registry value, located in the key HKEY_LOCAL_MACHINE\Software\Adobe\Flash\H264Profile.

Name Type Description Default Value

Max supported profile

REG_DWORD

Enables high-quality video playback on devices that support DirectShow hardware decoding.

None

The Max supported profile registry key is not set by default. You can add this registry key to indicate the highest H.264 profile that your hardware accelerated DirectShow filter video decoder supports.

If this registry key is set and video content is encoded in a profile greater than the Max supported profile registry value, then the Adobe Flash Player ActiveX control uses the default software decoder to decode video. If the video content is encoded in a profile less than or equal to the registry value, then the Adobe Flash Player ActiveX control uses the hardware accelerated decoder to decode video.

If this registry key is not set and your OS design includes a hardware accelerated DirectShow filter video decoder, then the Adobe Flash Player ActiveX control attempts to decode all H.264 video content by using the hardware accelerated decoder.

Set the registry value to the highest available profile supported by the hardware decoder, based on the following table:

Maximum supported profile Value

Baseline Profile

66

Main Profile

77

Extended Profile

88

High Profile

100

High 10 Profile

110

High 4:2:2 Profile

122

High 4:4:4 Predictive Profile

144

Typically, to create a run-time image with predefined settings, you add registry settings to the project's file before building the run-time image.

You can also use the Registry Editor in Platform Builder to add the settings to a device. However, changes that you make by using the Registry Editor do not persist to the registry files. Therefore, the next time that you download the image, you must configure the registry again. For more information, see Registry File.
