thank you.Can the video of this project be displayed on rgb lcd directly if i dont't connnect the VGA screen?
i have tried this idea,it don't work

iliasam commented

Sorry, I don't understand your question.
Note that "stm32F4_discovery_project" do not need any display, you cant try it first.

If I want to display the picture on rgb lcd, what do I need to change?

See https://github.com/iliasam/STM32_HOST_UVC_Camera/blob/master/HAL_source/stm32F429_project/Src/main.c

//Draw captured image
if (USBH_VIDEO_Target_Format == USBH_VIDEO_YUY2)
{
lcd_draw_yuyv_picture((uint8_t*)uvc_ready_framebuffer_ptr);
}
else
{
mjpeg_decompression_and_draw((uint8_t*)uvc_ready_framebuffer_ptr, uvc_ready_frame_length);
}
