PRB: Video for Windows Skips AVI Frames

 Last reviewed: May 25, 1995
Article ID: Q122775
The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) for Windows version 3.1
  • Microsoft Win32 SDK, versions 3.5, 3.51, and 4.0

SYMPTOMS

When Video For Windows is playing an AVI file, the processing power of the computer system and the data rate of the AVI stream determine whether frames will be skipped during playback. If the data rate exceeds the ability of Video For Windows to render all the AVI frames in time, Video For Windows will first try to catch up by decompressing delta frames but not drawing them. If Video For Windows still can't catch up, it will eventually skip all the way to the next key frame before it renders a new frame.

STATUS

This behavior of Video for Windows is by design and cannot be controlled by the application being affected.
