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 B101 capture boards made by Auvidea.
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 instructions to 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 configuration file) to use it.
