FIX: Flickering may occur after seeking when you play back interlaced content through the Video Mixer Renderer 9 (VMR9) with DXVA enabled in Windows XP (919071)


The information in this article applies to:

  • Microsoft Windows XP Home Edition
  • Microsoft Windows XP Professional

SYMPTOMS

When you play back interlaced content through the Video Mixer Renderer 9 (VMR9) with DirectX Video Acceleration (DXVA) enabled, flickering may occur after seeking.

CAUSE

This problem typically occurs when you issue a seek command while you play back content. In some cases, this command can cause the timestamps of the samples to be incorrect before the sample is sent to the de-interlacer. This behavior causes the even and odd fields to become reversed.
