Description

Methods such as CopyScreenToBitmap() from CWsScreenDevice, RHardwareBitmap or screen address retrieved with UserSvr::ScreenInfo() do not provide a way to capture screenshots of video playback currently in progress.

All above methods result in a blank rectangle being captured for the video area. This is because MMF video controllers do not hand the video frames over to the window server, but simply request a safe drawing region and use Direct Screen Access to render the decoded frames. Symbian OS does not provide access to raw LCD framebuffer.

Solution

No solution available.
