openCL 访问GL_IAMGE_KHR失败

chrone

我创建了Android graphic的buffer，

首先用eglCreateImageKHR创建了 image，然后用 clCreateFromEGLImageKHR创建cl_mem但是返回-30，我检查了参数没什么问题，是我创建上下文的参数缺少配置吗？

求大神帮忙看看~

glCtx->param.inImage = eglCreateImageKHR(glCtx->Display, glCtx->context, EGL_NATIVE_BUFFER_ANDROID, (EGLClientBuffer)glCtx->param.input, 0);
	glCtx->param.outImage = eglCreateImageKHR(glCtx->Display, glCtx->context, EGL_NATIVE_BUFFER_ANDROID, (EGLClientBuffer)glCtx->param.output, 0);
	LOGD("graphic handle is %p %p \n", glCtx->param.input, glCtx->param.output);
	if ((glCtx->param.inImage == EGL_NO_IMAGE_KHR) || (glCtx->param.outImage == EGL_NO_IMAGE_KHR)) {
		LOGD("eglCreateImageKHR err \n");
	}
	cl_int ret;

	
	clArg->memory[0].mem = clCreateFromEGLImageKHR(clArg->ctx, (CLeglDisplayKHR)glCtx->Display, ((CLeglImageKHR)glCtx->param.inImage), CL_MEM_READ_ONLY, 0, &ret);//(CLeglImageKHR)glCtx->param.inImage (CLeglDisplayKHR)glCtx->Display
	if ((clArg->memory[0].mem == NULL) || (ret != CL_SUCCESS)) {
		LOGD("clCreateFromEGLImageKHR err errNum is %d \n", ret);
	}
