AVPro flipped UVs / upside down in custom shaders solution

I came across the solution to getting flipped vertical UVs when feeding AVPro input into custom shaders and its surprising simple. You simply need to use the TRANSFORM_TEX unity macro using _MainTex_ST when passing the UVs in the vertex shader, this seems to automatically handle the UVs of the AVPro textures at least on PC. An example of this can be found in the unity default unlit shader, and in retrospect seems incredibly obvious.

Shader "TRANSFORM_TEX"
{
    Properties
    {
        _MainTex ("Texture", 2D) = "white" {}
    }
    SubShader
    {
        Tags { "RenderType"="Opaque" }
        LOD 100

        Pass
        {
            CGPROGRAM
            #pragma vertex vert
            #pragma fragment frag

            #include "UnityCG.cginc"

            struct appdata
            {
                float4 vertex : POSITION;
                float2 uv : TEXCOORD0;
            };

            struct v2f
            {
                float2 uv : TEXCOORD0;
                float4 vertex : SV_POSITION;
            };

            sampler2D _MainTex;
            float4 _MainTex_ST;

            v2f vert (appdata v)
            {
                v2f o;
                o.vertex = UnityObjectToClipPos(v.vertex);
                o.uv = TRANSFORM_TEX(v.uv, _MainTex);
                return o;
            }

            fixed4 frag (v2f i) : SV_Target
            {
                // sample the texture
                fixed4 col = tex2D(_MainTex, i.uv);
                return col;
            }
            ENDCG
        }
    }
}
