Welcome! Here are some of my projects:
UV4L, an User space Video4Linux framework:

UV4L is a simple framework aiming to provide Video4Linux2-compliant transparent, user space drivers (as plugins) for real or virtual video input devices, and other modules:
Please visit the documentation section for detailed informations and manuals. Installation instructions for Raspbian (Raspberry Pi, ARM). Generic, self-extracting archives for x86. Installation instructions for Ubuntu Raring (old).

Some projects in C++:

A wide collection of personal solutions to the exercises proposed by Bjarne Stroustrup in his well-known book The C++ Programming Language. Click here to browse the source code or here to download the archive.

Open source drivers, also present in the official Linux kernel:

See on-line documentations for a list of features and supported hardware.

Shortly after the announcement of the first release of the WebRTC extension for the UV4L Streaming Server, here's another update! As promised, Audio from an input device (i.e. microphone) can now be optionally added to the live stream!

A pure HTML5 test page is here.

Please read the documentation for all the available options.

Video & Audio streams have been successfully tested on Chrome, Opera, Firefox and Android. Due to a bug in Firefox prior to version 37.0, when audio is enabled, Firefox does not display the Video track. The problem has been fixed since v.37.

Have fun!

Yes, it's true! The native WebRTC extension for the UV4L Streaming Server is now ready!

At the moment, this extension is available for Raspberry Pi 2 only. Packages for x86 will be provided soon. The Raspberry Pi 1 will not be supported. Again, do NOT install the WebRTC extension on the Rasperry Pi 1.

To know how to install UV4L and the WebRTC extension please refer to the appropriate documentation section. Here are the instructions for Raspbian.

Support for audio is work-in-progress. Among the nice things which are now possible there are NAT traversal, VP8 encoding, efficient adaptive streaming, echo cancellation, encryption, very short delays, etc...

Once installed, to quickly try it, go to the Streaming Server page, navigate to the WebRTC Page and press "Start" to get a live stream. You can take the source of that HTML5 page and modify/use it as you prefer.

Tested on recent versions of Firefox, Chrome, Opera, Android. Safari does not seem to support WebRTC (deliberately).

A first screenshot (~200ms delay example) is here.

Have fun!
