Code Review

This pull request replaces all uses of eglCreateImage with its extension counterpart, eglCreateImageKHR, to enhance compatibility with older EGL versions. While the change is applied consistently across the codebase, a critical issue was found: the code does not check for the availability of the EGL_KHR_image_base extension before using eglCreateImageKHR. This could lead to a crash on systems that do not support this extension. A recommendation to add this check has been provided.

critical

Using eglCreateImageKHR requires the EGL_KHR_image_base extension. This code does not check if the extension is available before calling the function. If the extension is not supported, epoxy may not resolve eglCreateImageKHR, which could lead to a crash when a nullptr function pointer is called. A check for the EGL_KHR_image_base extension should be added before calling eglCreateImageKHR to prevent this.

You will also need to include <string.h> at the top of the file for the strstr function.

  const char* extensions = eglQueryString(egl_display, EGL_EXTENSIONS);
  if (extensions == nullptr || strstr(extensions, "EGL_KHR_image_base") == nullptr) {
    g_warning(
        "Failed to create EGL image: EGL_KHR_image_base extension not "
        "supported.");
    return nullptr;
  }
  return eglCreateImageKHR(
      egl_display, egl_context, EGL_GL_TEXTURE_2D,
      reinterpret_cast<EGLClientBuffer>(static_cast<intptr_t>(texture_id)),
      nullptr);
