So my projects should open and close garage door while streaming video.
i can get my device online in blynk but no video streaming.

@Gytis Please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```
Copy and paste these if you can’t find the correct symbol on your keyboard.
Pete.
Thank You for respons i edited my post.
Your code is a mashup of stuff that makes no sense.
You don’t appear to be running the code that streams the video, but it’s difficult to tell without seeing the original code.
When you have this working, and are able to view the video stream in a browser on the same network, then there are quite a few steps to go through to make the video stream accessible via the Blynk app. This has been discussed quite a few times before, if you search for recent posts regarding the ESP32 CAM board you’ll see some info on this.
Pete.
So i maneged to fix my code to some extent. Now Buttons works on blynk, But my Video streaming in not. First thing i cant get the serial print to print ip address. And if i use my old ip addres i cna connect to video but no post on blynk.

Go back to your source for this sketch and see if there is a line of code that calls the startCameraServer function.

Hello Pete,
I got the reference code I used to test the camera.
My project’s deadline is coming up really soon and basically I am running out of time to make this project to work. Everything I tried only got me more error codes… And I have to leave it for now and hope I’ll find a little more time to try something.
My reference code:

The last line of the void setup in this “reference code” contains the command to call the startCameraServer function.
Your code is missing this line, so your sketch isn’t launching the web server that streams the video image.
You should have been able to figure this out yourself, because I already asked you about this line of code…
Pete.
I think i fixed what you said, but now it doest connect to wifi?

Your mashup of code is probably responsible for that.
I’d start by removing your Blynk.begin command.
Pete.
Okey i removed Blynk.begin.
But still not connecting to wifi

Do you have anything connected to your board other than the USB cable and the camera?
It appears that something is preventing your board from booting into run mode.

}And have you tried disconnecting it and seeing if that allows your board to boot?
Pete.
I tried it doest help.
If that’s all you’re seeing in your serial monitor and you have nothing connected other than the camera and the USB cable then you appear to have a hardware problem.
Pete.
i got it to next stage 
Serial monitor displaying this:
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee

entry 0x400805f0
WiFi connected
Camera Stream Ready! Go to: http://0.0.0.0Blynk Not Connected
Blynk Not Connected
Blynk Not Connected
in my code i added
Serial.begin(115200);
delay(1000);
Your latest code…
Your previous code…
Your board doesn’t appear to be getting an IP address, probably because of what you’ve done above with the WiFi connection part of your void loop.
You should also add:
#define BLYNK_PRINT Serial
near the top of your sketch, it will give you more info about the Blynk connection process and status.
Pete.
