v2l

Video4Linux (V4L for short) is a collection of device drivers and an API for supporting realtime video capture on Linux systems. It supports many USB webcams, TV tuners, and related devices, standardizing their output, so programmers can easily add video support to their applications.
Video4Linux is responsible for creating V4L2 device nodes aka a device file (/dev/videoX, /dev/vbiX and /dev/radioX) and tracking data from these nodes. The device node creation is handled by V4L device drivers using the video_device struct (v4l2-dev.h) and it can either be allocated dynamically or embedded in another larger struct.
Video4Linux was named after Video for Windows (which is sometimes abbreviated "V4W"), but is not technically related to it.While Video4Linux is only available on Linux, there is a compatibility layer available for FreeBSD called Video4BSD. This provides a way for many programs that depend on V4L to also compile and run on the FreeBSD operating system.

    Charging 12v battery using a V2L lead connected to the same car?

    There are a few threads on here about MG4 12v battery failures that have caused numerous issues. I park my car well away from any plug that I could use for a battery charger so I am wondering if I could use my V2L cable connected to my car to attach a battery charger to charge my 12v battery...

    Both myself and my neighbour have our MG4s wired to our household consumer units to run the house directly from V2L. We were told the MG4 output only 2.2kW, Our old Kia EV6 output 3.5kW. Today we decided to push them as far as we could.. With a meter on the input, we ran 2x 600W IR Heating...

    Connecting a V2L car to a house as a battery.

    Ok, I know the difference between V2G and V2L. You cannot connect a car with V2L to the house power supply because it cannot sych with the phase of the grid and an explosive outcome will result. Would it instead be possible to connect via a DC convertor to a solar DC invertor instead to power...

    Anyone for a v2l cuppa of MG Tips? 😉

    We enjoyed a nice cup of tea at Rutland Water earlier using the V2L adapter. Worked well once I realised that I needed to get into charging menu and set a minimum battery level. Couple of minutes later we had 2 cuppas made with 'electric water'.

    V2L upgrade?

    Having accidently got the specs of the 2022 model and my 2021 one confused I got very excited about the new v2l cables that have been released. Does anyone know if the old mg5 can be modified to use the cables? Or is there simply too much that needs changing for it to be economical?

    Hi. Does anyone know the best procedure for using the mg4 with a v2l cable? I'm looking to take a washing machine/dryer off grid if possible, and it's connected load is 2000w. What concerns me is that on another thread it was said that the lights need to be left on, which would be a bit of a...

    Hi I have the first edition of MG ZS EV but considering the new edition because of the range, app and the V2L function. But due to the high energy prices, I was wondering I could connect my home heatpump to the V2L on the car, of course of the grid in the house.

    V2L, V2H, V2G - How does it work with MG EVs?

    Hi all, new to the forum. Ordered an MG4 a week ago and expecting delivery in the second shipment Oct/Nov. Having done a bit of research on V2G it still seemed a way off with only one very expensive chademo bidirectional charger model out, so I was about to order an Easee charger. Then on...
