Real-time HTTP/HTTPS Streaming Server with the native uv4l-server module. The uv4l-server module is a plug-in specific for UV4L which enables a per-camera Streaming Server that can be simultaneously accessed by any browser over HTTP or HTTPS protocols..

IP CAMERA) INTO A With UV4L and the mjpegstream driver it’s possible to make any source of MJPEG streams over HTTP (e.g. an IP camera) appear as a camera physically connected to the Raspberry Pi so to make it transparently accessible by any Video4Linux2-compliant applications, including the powerful UV4L Streaming Server and WebRTC module themselves which open the door to an infinite number of WEBRTC DATA CHANNELS By means of UV4L, WebRTC data channels allow real-time, secure and full-duplex data exchange between a remote WebRTC-complaint peer (e.g. a browser) and a third-party application running on localhost. By default the data channel is bundled onto the same transport as audio and video tracks (if present) in one peer connection.

PLAYING RETROPIE GAMES IN THE BROWSERThis is a tutorial
and below is the demo which shows a new way to play RetroPie games with an HEADLESS Raspberry Pi 3B+ and an Android “terminal” in the same LAN: traditionally the Raspberry Pi is directly wired to display, speakers (where the game is rendered ) and a gamepad controller. In this case, however, the Raspberry Pi is _NOT_ connected to any display (except in the first part of the demo for clarity), speakers and controller. On the contrary, the game is played from within Android _Chrome_ on an smartphone with a gamepad controller connected to the smartphone itself. In other words, the game video and audio are rendered onto the smartphone screen and speakers. The great thing is that no special, third-party application on the smartphone is required other than the stock Chrome browser. CONTENT NOT AVAILABLE.

NEW SCREENSHARING WEB APP FOR RASPBERRY PIIn this example
we will see how to configure the Raspberry Pi to serve a customizable _web app_ which allows the _Raspberry Pi_ to share its screen and speakers (“what you hear”) to the PC browser. Additionally, thanks to a virtual keyboard running on the Raspberry Pi, it will be possible to emulate the keypresses captured and sent from within the web pagein the browser.
It can be used to fully play _RetroPie_ games in the browser as shownin this DEMO.

FILE TRANSFER VIA WEBRTC DATA CHANNELS WEBRTC DATA CHANNELS can be used for an infinite number of useful things. They are ideal for sharing data between two peers in a secure and efficient way. In a past demo we showed how they could be used to control a robot in real-time. In this demo we will see how to use a WebRTC data channel to transfer a file from a browser to a Raspberry Pi. The demo can also work as a simple remotemedia player.

UV4L USED IN COMPUTER VISION! webrtcH4cKS has recently posted a very interesting article about a computer vision project that makes use of _UV4L_ for real-time streaming of video and data over _WebRTC_ from a _Raspberry Pi Zero_ connected to a _AIY Vision_ board. The board embeds a Vision Processing Unit (VPU) chip that runs Tensor Flow image processing graphs superefficiently.
The article is divided in two parts:* part 1
* part 2

UV4L NOW SUPPORTS THE TC358743 HDMI TO MIPI CONVERTER CHIP The Video4Linux2 _uv4l-raspicam_ driver for Raspberry Pi has been extended to support the _TC358743_ _HDMI_ to _MIPI_ converter chip. This chipset is often found in the B101capture
boards made by Auvidea. Any resolution, color space or hardware codec (like _MJPEG_, _H264_, _YUV_s, etc…, with or without preview) will work. All the UV4L components on the top of this driver will work as usual. The Raspberry Pi 3 is supported by this new release of the _raspicam_ driver, while support for other Raspberry Pi models can be activated upon request . Upgrade the driver or read these instructionsto know how to
install it. Remember that the _TC358743_ in the driver has to be enabled via the _–tc358743=yes_ option (e.g. in the configurationfile) to use it.

HOW TO DEPLOY AND RUN A CUSTOM WEB APP WITH UV4L This is a long-awaited tutorial showing how to deploy and serve a custom _web app_ through the _UV4L Streaming Server_. The example web app does very little other than embedding a live video stream from a remote camera into a STANDARD HTML5 page and processing it in real-time to perform face detection with PLAIN JAVASCRIPT. It’s a good starting point for more complex things that can be done in a browser (and not only!).Author webmaster

UV4L WEBRTC HAS NOW LANDED ON THE RASPBERRY PI ZERO AND ZERO W MODELS!The UV4L WebRTC
extension is
finally available for the following models as well: _Raspberry Pi 1_, _Raspberry Pi Zero_ and _Raspberry Pi Zero W (Wireless)_. For the installation instructions click here.
Remember that these models have less CPU power than the Raspberry Pi 2 and 3 counterparts, so please consider experimenting with “modest”resolutions first.
Users of other Rpi models, however, are also suggested to upgrade the UV4L packages to the most recent release as includes general improvements and new options, especially for the _Streaming Server_ module and the _raspicam_ driver (e.g. it’s now possible to disable image processing blocks in the ISP).Author webmaster
