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).
