function GstGL.prototype.gl_video_format_swizzle(video_format: GstVideo.VideoFormat): {
    // javascript wrapper for 'gst_gl_video_format_swizzle'
}

Calculates the swizzle indices for video_format and gl_format in order to access a texture such that accessing a texel from a texture through the swizzle index produces values in the order (R, G, B, A) or (Y, U, V, A).

For multi-planer formats, the swizzle index uses the same component order (RGBA/YUVA) and should be applied after combining multiple planes into a single rgba/yuva value. e.g. sampling from a NV12 format would have Y from one texture and UV from another texture into a (Y, U, V) value. Add an Aplha component and then perform swizzling. Sampling from NV21 would produce (Y, V, U) which is then swizzled to (Y, U, V).
