In Bink video how to eliminate the black pixel setting the Alpha =0 during at playback time?
In Allegro5 I set a Background image and create a popup new window where I show a .bik video.
This .bik video has black backgroud and has not Alpha Channel when the frame is decompressed.
I need set transparency where black pixel appear. So the main window background can be visible.
I have the RAD SDK.
In a call to Blit_RAD_3D_image (Blit a 3D image onto the render target) I have this:
if ( rad_image->download_textures )
{
Submit_texture( pixels,
rad_image->row_length,
rad_image->maximum_texture_size,
rad_image->maximum_texture_size,
rad_image->gl_surface_type );
}
//
// Submit the vertices.
//
Submit_vertices( dest_x,
dest_y,
x_scale,
y_scale,
rad_image->maximum_texture_size,
rad_image->maximum_texture_size,
alpha_level,
is_premultiplied_alpha );
VS2010 C++.
Thank you.
