I am trying to copy ffmpeg vaapi frame to opengl. so i use vaCopySurfaceGLX() to do it, but it return VA_STATUS_ERROR_UNKNOWN

Linux amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.90-1 (2024-05-03) x86_64 GNU/Linux

Here is my code.

GLuint texture;
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, frame->width, frame->height, 0, GL_RGBA, GL_UNSIGNED_BYTE, nullptr);
glBindTexture(GL_TEXTURE_2D, 0);
void *gl_surface;
st = vaCreateSurfaceGLX(va_display, GL_TEXTURE_2D, texture, &gl_surface); //return 0
std::cout << "careate stauts is " <<  st << std::endl;  
VASurfaceID id = (uintptr_t) frame->data[3]; //frame created by same va_display
st = vaCopySurfaceGLX(va_display, gl_surface, id, VA_FRAME_PICTURE); //return -1
std::cout << "Copy status is " << st << std::endl;

May be Texture format error? I can't find any example about how to use this api.

You may refer to https://github.com/gbeauchesne/mplayer-vaapi/blob/hwaccel-vaapi/libvo/vo_vaapi.c, but the recommended way is to map a vaapi surface to an egl image, then use this egl image. You should be able to find lots of examples.
