Default FrameType Causes BGRA Frame Output RGBA

[MrAdhit]

When I set output_type to default, the frame format is in RGBA even tho it uses the BGRA enum,
this doesn't happen if I specify the output_type to BGRA explicitly

here's the reproducible code

Hey, thank you for pointing out the issue!

This behavior occurs because of the ColorFormat being set here

let color_format = match options.output_type {
        FrameType::BGRAFrame => ColorFormat::Bgra8,
        _ => ColorFormat::Rgba8,
};

which sets the color format of any other frameType as Rgba8 which was causing the issue as the default FrameType is set as YUV frame as you can see here

#[derive(Debug, Clone, Copy, Default)]
pub enum FrameType {
    #[default]
    YUVFrame,
    BGR0,
    RGB, // Prefer BGR0 because RGB is slower
    BGRAFrame,
}

@RohanPunjani I think the problem is that only BGRA frames are sent from the capturer:

I think I might be ahving a similar issue with #110
