发布微信小游戏报了一个错误，跟下面链接的问题一模一样：
https://forum.cocos.com/t/cc-rendertexture-create-gl-teximage2d/58801
后来按照引导，修改引擎源码后，重新编译gulp build
重新发布后，提示错误：

补充下图片：
1.这张是修改引擎源码的
2.微信开发工具报错
在加载首个场景的时候就报错，请教如何解决？
再补充下图片：
源码改成：
_p._setImage = function(img, width, height, glFmt, premultiplyAlpha) {
var gl = this._gl;
gl.pixelStorei(gl.UNPACK_PREMULTIPLY_ALPHA_WEBGL, premultiplyAlpha);
var ret2 = img instanceof HTMLCanvasElement && !(img instanceof Uint8Array);
var ret4 = img instanceof HTMLVideoElement;
sys.platform === sys.QQ_PLAY || ret2 || img instanceof HTMLImageElement || ret4 ? gl.texImage2D(gl.TEXTURE_2D, 0, glFmt.internalFormat, glFmt.format, glFmt.pixelType, img) : gl.texImage2D(gl.TEXTURE_2D, 0, glFmt.internalFormat, width, height, 0, glFmt.format, glFmt.pixelType, img);
};
提示HTMLVideoElement is not defined?求救SOS！！！
