I got yet another idea with integrating IP camera with Blynk. Using webhook widget I want to control a functioning PTZ IP camera. Already tried with http and it works. Unfortunately more important tasks are pushing it back…
Hi @Gunner, thanks for sharing!
Just one question about the video, do you observe delays between frames?
I’ve got a 15€ Wi-Fi camera (the cheapest I found it) attached at a car and it is complicated to control it due to the delays, I have to wait about one second or so to refresh the video and know where it is to move the car a little bit more.
There is about a second delay/lag that is only noticeable on the Blynk App. The web view is almost spot on. But the video flow itself is smooth in the App. I might add in a video of the video later.
That particular web streaming library is only for the PiCamera (and way overkill for my needs)… but I suspect there are other options out there.
I think it is all about buffering… In IP cameras I’m using the buffer is dynamically assigned based on connection quality to achieve smooth playback. If however the buffer is assigned statically and there is no control about it, I think there is little you can do.
I just added in code to start and stop the video stream with a Button in switch mode…
Figuring out all these brackets in javascript makes C++ look simple
// ----- Pi Video Stream -----
var PiCamStream = new blynk.VirtualPin(24); // Setup PiCam Video Streaming Switch on V24
PiCamStream.on('write', function(param) { // Watches for V24 Button/switch
if (param == 1) { // Runs this CLI command if the switch on V24 is ON
process.exec('RPi_Cam_Web_Interface/start.sh', function (err, stdout, stderr) { // Start Streaming
if (err) {
console.log("\n" + stderr);
}
})
} else { // Runs this CLI command if the switch on V24 is OFF
process.exec('RPi_Cam_Web_Interface/stop.sh', function (err, stdout, stderr) { // Stop Streaming
if (err) {
console.log("\n" + stderr);
}
})
}
});
Such as I’m newbie on this things, should you, please, help me to get It working? I would like only to show the rpiwebcam interface onto the video widget on blynk app.
This project/topic was a long time ago… and I don’t hang out here much anymore, so unable to assist.
If viewing the simple streaming is all you want, then aside from the Video Widget, Blynk is not involved in the process and all you need to focus on are these two aspects I had already posted above.
And I recommend you Google for other RPi Camera streaming options (there are many out there) and try those URL’s in the Video Widget… such as …
later.
