TRTCSDK自定义采集Texture2D视频通话
方案： 本篇主要介绍Texture方案：使用安卓系统封装的camera2+GLSurefaceView，采集到OES纹理，使用FBO复制成Texture2D纹理离屏渲染，将纹理ID交给TRTCSDK编码传输 ：采样器 采集 aCoord的像素 //赋值给 gl_FragColor 就可以了 gl_FragColor = texture2D(vTexture,aCoord); } 再实例化CameraFilter float; varying vec2 aCoord; uniform sampler2D vTexture; void main(){ gl_FragColor=texture2D 比如美颜操作、水印操作等，都需要处理纹理，将处理之后的Texture2D纹理渲染出来。 image.png 注意，目前TRTCSDK，传输纹理格式，仅支持Texture2D格式，不支持OES格式，而android系统carmera2采集的纹理格式，是OES格式的。

{ public: texture2d() { gpu_texture = texture_create(); } ~texture2d { public: texture2d() { rhi::texture_create(this); } ~texture2d 第三种方案和第二种方案有一个通病，就是一个texture2d资源同时需要至少两个对象来表示，render层的texture2d和vulkan层的gpu_texture2d, 这会造成内存碎片问题。 伪码如下： //-----render/texture2d.h namespace render { class texture2d { pubilc: static texture2d *create(int width, int height); static void destroy(texture2d *tex); protected: texture2d
