#define FE2_OVERLAY_MASK_RGB
Use the RGB value (
) as the transparency color.
Remarks:
The color specified will become transparent when the overlay image is drawn on the video image.
Setting this parameter will disable
if it has been set.
Using a PNG or bitmap with full alpha channel will produce better results than using a transparency
color.
If using this method to add an overlay to video with an existing alpha channel, the transparent portions
of the overlay will be transparent in the output video. Opaque portions of the overlay will be averaged
with the existing alpha data.
