Real Time Streaming

Question

Hello!

Has anyone tackled Real Time Streaming yet?

In a nutshell, I'd like to stream video from a hardware device to my cell phone, and it has to be close to real time. A 1 second delay is fine, a 10 second delay isn't.

A lot of technology of this nature is designed for things like Live sporting events and conferences, and they often have latencies of 30 or more seconds, which is too much.

The tech I'm thinking of is like a doorbell - someone is at the door and I'd like to see who it is immediately.

To simulate for testing, I'll likely want to stream from a Raspberry Pi (I have USB webcam and PiNoir to choose from). To test the source stream, I hear that VLC player can handle the playback well.

The main question is - what technology/libraries can be used for this?

edit: I need to view the results within an app - Ideally I'd like to just use the built-in media players, like AVPlayer for iOS, which seems to prefer HTTP Live Streaming.

also ps, there are some RTSP libraries available for iOS (like kxMovie), but their licensing cannot be used commercially.

Thanks!

Hello ntewinkel , Have you tried "mjpg streamer" for Raspberry Pi? It works pretty well with low latency. You can stream the Raspi Camera on any of the browser. Here is a nice guide to help you get started with it. Abhijit.

ntewinkel if you want to integrate it into a mobile app, you definitely can! Once you can stream on a browser on a localhost, just use the port forwarding and the Dynamic DNS service to map the forwarded port to a domain by DDNS. Once done, you could easily have "web viewer" in an android app to open the URL right within your app. I had helped with such a solution to a friend on his project and works pretty well.
