Here are a couple of minor nits to consider while you redo the parts we talked about in person.

> Source/WebCore/platform/graphics/avfoundation/CDMFairPlayStreaming.cpp:189
> +    SchemeAndKeyResult result;

Minor nit: you can define this just before the loop so it isn't allocated if the array buffer allocation fails.

> Source/WebCore/platform/graphics/avfoundation/ISOFairPlayStreamingPsshBox.cpp:64
> +    if (m_size - (localOffset - offset) < 16)
> +        return false;
> +
> +    auto buffer = view.possiblySharedBuffer();
> +    if (!buffer)
> +        return false;
> +
> +    auto keyID = buffer->slice(localOffset, localOffset + 16);
> +    localOffset += 16;
> +
> +    m_keyID.resize(16);
> +    memcpy(m_keyID.data(), keyID->data(), 16);

Nit: "16" should be a named constant.
