Unity 全景视频播放

1、建立一个球sphere ，把相机放置在球中，设置球的shader

2、新建一个Render Texture，设置Render Texture的size和视频的大小一样

2、建立一个videoplay,设置videoClip和TargetTexture属性

球的shader

Shader "Custom/InsideVisible" {

	Properties{
		_MainTex("Base (RGB)", 2D) = "white" {}
	}

		SubShader{
		Tags{ "RenderType" = "Opaque" }
		Cull front    // ADDED BY BERNIE, TO FLIP THE SURFACES
		LOD 100

		Pass{
		CGPROGRAM
#pragma vertex vert
#pragma fragment frag

#include "UnityCG.cginc"

		struct appdata_t {
		float4 vertex : POSITION;
		float2 texcoord : TEXCOORD0;
	};

	struct v2f {
		float4 vertex : SV_POSITION;
		half2 texcoord : TEXCOORD0;
	};

	sampler2D _MainTex;
	float4 _MainTex_ST;

	v2f vert(appdata_t v)
	{
		v2f o;
		o.vertex = UnityObjectToClipPos(v.vertex);
		// ADDED BY BERNIE:
		v.texcoord.x = 1 - v.texcoord.x;
		o.texcoord = TRANSFORM_TEX(v.texcoord, _MainTex);
		return o;
	}

	fixed4 frag(v2f i) : SV_Target
	{
		fixed4 col = tex2D(_MainTex, i.texcoord);
	return col;
	}
		ENDCG
	}
	}
}
