Adjusts the aspect ratio of the video frames before applying the overlays
Declaration
property AdjustOverlayAspectRatio: Boolean read GetAdjustOverlayAspectRatio write SetAdjustOverlayAspectRatio default DEF_AdjustOverlayAspectRatio;
__property bool AdjustOverlayAspectRatio=read=GetAdjustOverlayAspectRatio, write=SetAdjustOverlayAspectRatio, default=1
Property AdjustOverlayAspectRatio As Boolean
Description
Used to adjust the aspect ratio of the video frames before applying the overlays.
This property applies only only when the aspect ratio of the video source does not match the size of the video frames (e.g. a 16x9 aspect ratio for a 720x480 native video size)
AdjustOverlayAspectRatio enabled (requires a few CPU more):
The video frames are resized to their display aspect ratio before the overlays are applied, so the aspect ratio of the overlays is correct.
AdjustOverlayAspectRatio disabled (saves CPU):
The video frames are not resized, the overlays are applied to the native video size.
If the video is displayed to its correct aspect ratio (e.g. when Display_AspectRatio = ar_Box), the video frames will be stretched, including the overlays that may appear distorded.
