I needed to integrate a video stream into my Blynk project. I scoured the forums looking for the correct camera and code. There were some hints but nothing really definitive to go on. I fell back on what I needed for my hardware and Blynk. I needed 5V with the easiest integration to a power source (i.e. USB) and Blynk requires a URL to feed into the stream widget. I settled on the Nest Cam Outdoor. Brand name and readily available. It has a USB that can be plugged directly into a 5V battery or a transformer to plug it into the wall. You can also get a direct link to the URL feed through your Nest account. Setup your camera according to the directions. Obtain the URL in the sharing options. It will look something like this:
https:/video.nest.com/live/klk43l4kh35kjh
Entering this URL directly (hardware or app) into Blynk will return an error. Doing some digging led me to iSpy. They have an applet that converts the Nest URL into a usable format. Follow this link and input the Nest URL.

The resulting URL should look something like this:
https://stream-us1.alfa.dropcam.com:453/nexus_aac/85dsdlgksajglasdkhgflc75/chunklist_w20433534501651.m3u8
Input the following code outside of the void functions
BLYNK_WRITE(V2)
{
Blynk.setProperty(V2, "url", "https://_insert camera URL here_");
}
Insert URL in the widget and set the corresponding virtual pin.
Worked on the first try. Hope this helps people in the quest for simpler video streaming.
