LWRP and Video Player with Alpha

I'm using this shader to manage a video with alpha in my video player on Unity:

Code (JavaScript):

1. Shader "Custom/VideoAlphShader" {
2.      Properties {
3.          _Color ("Color", Color) = (1,1,1,1)
4.          _MainTex ("Albedo (RGB)", 2D) = "white" {}
5.          _Glossiness ("Smoothness", Range(0,1)) = 0.5
6.          _Metallic ("Metallic", Range(0,1)) = 0.0
7.          _Num("Num",float) = 0.5
8.         _Alpha("Alpha",float) = 1
9.  
10.     }
11.  
12.     SubShader {
13.          Tags { "Queue"="Transparent"  "RenderType"="Transparent"  "RenderPipeline" = "LightweightPipeline"}
14.          LOD 200
15.  
16.         CGPROGRAM
17.      #pragma surface surf NoLighting alpha:auto
18.  
19.      fixed4 LightingNoLighting(SurfaceOutput s, fixed3 lightDir, fixed atten)
20.          {
21.              fixed4 c;
22.              c.rgb = s.Albedo;
23.              c.a = s.Alpha;
24.              return c;
25.          }
26.      float _Num;
27.      float _Alpha;
28.  
29.         sampler2D _MainTex;
30.  
31.         struct Input {
32.              float2 uv_MainTex;
33.          };
34.  
35.         half _Glossiness;
36.          half _Metallic;
37.          fixed4 _Color;
38.          UNITY_INSTANCING_BUFFER_START(Props)
39.          UNITY_INSTANCING_BUFFER_END(Props)
40.      void surf (Input IN, inout SurfaceOutput o)
41.          {
42.              o.Emission = tex2D(_MainTex, IN.uv_MainTex).rgb;          
43.            
44.             if (_Alpha == 1) {
45.                 if (IN.uv_MainTex.x >= 0.5)
46.                 {
47.                     o.Alpha = 0;
48.                 }
49.                 else
50.                 {
51.                     o.Alpha = tex2D(_MainTex, float2(IN.uv_MainTex.x + 0.5, IN.uv_MainTex.y)).rgb;
52.                 }
53.             }
54.             else {
55.                 o.Alpha = 0;
56.             }
57.         }
58.          ENDCG
59.      }
60.      FallBack "Diffuse"
61. }

I want to use LWRP on Unity but if I enable the LWRP this shader doesn't work.
Is it possible or not? Can I update in some way my shader to work with LWRP?
Thanks for the help.
