Yes, you can video stream the ESP32 camera on blynk “Video Stream” widgets like blynk1.0,
but in Blynk2.0, you need to upgrade your Blynk app to pro version.

I have posted videos on different Methods to connect with new blynk.
In below video, I have shown the easiest way-

You need to add the MPU sensor code in the code and that’s it.
compilation error 'class blynk wifi' has no member named 'notify' pleas reslove this
Must put all the header files inside the programming folder, change the credentials and follow all of the instructions shown in the video. I will work.
compilation error 'class blynk wifi' has no member named 'notify'

My code is working fine, I can see the Ready after i reset on Serial monitor, Also basic codes are also working on node mcu. but when i upload the code and search for Device my app is not able to connect with nodemcu. I also used 2Amp 5v adapter but unable to connect.
Ok. Have you connected your board to blynk before?
@@SMEDehradun No, I have 2 Node Mcu Boards I am trying to Connect, One Node MCU is showing ESP_0FE94A, When I search the WiFi. But when I click on it it says: Couldn't Get IP Address. Also when I search using Blynk App it does not connect. I have cleared the EPROM Also

Hello i already installed the blynk library but it still keeps on showing compilation error :BlynkEdgent.h: No such file or directory
Hi,
If you have seen the video properly, then addon header files must be inside the programming folder.
It's already in the programming folder
What error you are getting?
the same error it always say no such file or directory
@@allansuarez4506 can you tell which video you are following? share the link.
In the video, you ask us to replace #define BLYNK_DEVICE_NAME "Change it" with the text copied from the template firmware configuration section of the Blynk.Console. However, the variable there is no longer called "BLYNK_DEVICE_NAME". Now it is called "BLYNK_TEMPLATE_NAME". This causes an error that can be fixed easily by changing everything to ""BLYNK_DEVICE_NAME". Why are these two variables different? "Device_Name" implies it is the name of an individual device, however, you are clearly pasting in the name of the template.
This is recently changed that made by blynk.
So we just have to change the BLYNK_DEVICE_NAME to BLYNK_TEMPLATE_NAME?
Just copy paste the credentials from your blynk project to your code.

Thank you sir for the useful information.
Most welcome
I am geeting an error"old version of blynk library is in use. Please replace it with the new one" i also replace it with new library still the same error can u give solution for this
Hi Tejaswini,
You need to delete the old Blynk library from your Arduino IDE.
If you can update the blynk library as shown in video.
Try this, It will resolve this error. And if not resolved, then let me know. We will help you.
when im uploading my own code the app is not working
Have you are using the blynkedgent function to connect with new blynk, then connect your board through the blynk IoT app otherwise you can use alternate method to connect.
See this video how to connect like old blynk.

hello sir do you know why the coding say 'class BlynkWifi' has no member named 'email'? Hope you help me sir
There must be header file included in the programming folder. Plz watch the video properly and follow each and every step. Also add the latest blynk library in Arduino IDE.
This video will help you for it.

I am not asking you about the library. That’s great that you have install all the library. But I am asking to add all the header in the program folder.
Why don’t you see the video properly?

Yes you can.

Hi,
I didn’t get you point.

This is the issue because of header files.
You need to have all the headers inside the programming folder. Also check that you have installed the latest blynk library. If you are not able to connect your baord to blynk using blynkedgent method Then you can another method to connect.
Below is the video that can show how you can-

Disconnect all the connection from NodeMCU and the try it once again. If this will not work, then erase the eeprom of the esp8266 board and try again.

It may due to token is different or may be there is some issue with token.
So check it or make new template & try to reconnect.
hai, i already follow your instruction to clear trash in eeprom, but the notice on my arduino IDE is still there, it's written : "error for compiling ESP32 board' . I using ESP WROOM32 . Do you have solution for this? thanks.
This is not the eeprom error. There may possibility of syntax error in your code. So select the appropriate board & then compile. Library & header files must be included.
i'm using your demo code and i think its fine with the code. I also have selected the correct board because my board be able to execute previous program I put on. Full error code seen like this:
