LGTM - at least I can say that for the first one, which I have
for many years already. My current list at this place is this:

static const struct {
    DXGI_FORMAT d3d_format;
    enum AVPixelFormat pix_fmt;
} supported_formats[] = {
    { DXGI_FORMAT_NV12,            AV_PIX_FMT_NV12 },
    { DXGI_FORMAT_P010,            AV_PIX_FMT_P010 },
    { DXGI_FORMAT_Y210,            AV_PIX_FMT_Y210 },
    { DXGI_FORMAT_P8,              AV_PIX_FMT_PAL8 },
    { DXGI_FORMAT_B8G8R8A8_UNORM,  AV_PIX_FMT_BGRA },
    { DXGI_FORMAT_P016,            AV_PIX_FMT_P016 },
    { DXGI_FORMAT_YUY2,            AV_PIX_FMT_YUYV422 },
    // Special opaque formats. The pix_fmt is merely a place holder, as the
    // opaque format cannot be accessed directly.
    { DXGI_FORMAT_420_OPAQUE,      AV_PIX_FMT_YUV420P },
};
