Video decoder configuration

To get to ffdshow's video decoder options dialog, click on “Start” → “All programs” → “ffdshow” → “Video decoder configuration”.
Alternatively, while playing a video, double-click the red ffdshow video icon in the notification area of the task bar. Most settings can be changed during playback and take effect immediately, while codecs, output colorspaces, queue and some other settings need a restart of the video application in order to take effect.
