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.

    Same plug for charging and or V2L

    I want to make a plug which can be used for both charging and V2L But I do not have an MG4 yet. My question is: What happens if the V2L plug is removed from the car when V2l is active and the plug is replaced by the normal AC type 2 charger plug ? Is there something one must do inside the car...

    V2L - Constant load to keep working?

    Looking at trying the V2L function on the MG5 facelift and just wondering if anyone knows if it needs constant load to keep working? For example for a fridge or freezer, they won’t be on constantly, so would the V2L turn off as there is no load? If so is there a set amount of time it would be...

    V2L Earthing - how?

    I cannot seem to find any clear answer on this. How, if at all, does the V2L system provide an earthing system? There is no actual connection to earth, but does it need one? I’ve read there is some form of in built RCD but I’ve also read no such thing exists. Is an RCD even needed if it is a...

    V2L programming unloading.

    I understand it is NOT possible to start MG4 V2L unloading using a switch at the outside of the car. it must be activated from inside the car. Using an ionic 5 V2L it is possible to start unloading using a switch in the socket. this means unloading can be started from a distance using a...

    V2L adapter cable adaptor - £ 6.20 vs £500

    Errr....so, Ali Express are selling a V2L adapter cable for £ 6.20 while my dealer is selling it for around £ 500. And I'm seeing a German guy who makes his own(don't do that) and shows that it is not gold and jewels inside the V2L that cost £500. I have also seen one to 169,40€ I'm not gonna...

    Should a new MG4 Trophy come with the Type 2, Granny and V2L cables ?

    Hi all, new here. Just ordered a Trophy today - due to pick up 15/02 as its at the dealers already. Reading through this forum I see several adverts for people selling Type 2 / V2L cables but I would expect these to come with the car as standard. Is this not the case ? Is there anything else I...

    V2L… again…

    And so it would appear that some people can use V2L with a stopped ‘n’ locked car while some others (like myself) can’t. There’s this guy on YouTube who clearly shows he’s able to turn off and lock the car (the video is in German, but you can use auto translated captions in English). My ZS...

    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...

    V2L switching off after a few seconds ZS EV 2022!

    V2L Test. 7kW output...

    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'.
