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.

    mg4 2023 model V2L adapters/cables not working?

    Reading around seems these adapters are not working on MG4 MY23 models? Basically those built after end of March 2023. Anyone know if there's a way around this? Not sure if its to do with the new ones being single phase only affecting the connections? I have no knowledge on this stuff, just...

    Quasar 2 - EV Charger

    This looks interesting. The MG4 has V2L capability and some have wired sheds etc to take advantage of that. But this looks like a game changer, 2 birds with one stone, although that stone may be an expensive one Quasar 2 Charger with integrated V2L (your home)

    Does anyone offer something like a V2L socket inside the vehicle?

    I know it's only day 2 of my ownership It seems to me that a 13A (BS 1363) covered/ switched socket inside the vehicle might be nice to avoid having to have a V2L cable dangling out the front. Does anyone provide such?

    MG ZS missing V2L function

    Hello, I recently purchased an MG ZS EV LR Trophy Connect and attempted to use the V2L function. I tried various power states for the car, ensure it had decent charge etc however it refuses to start providing power. I have ordered a different cable for testing purposes but I note that others...

    V2L Again.... sorry

    V2L discharge and lock up car over night

    I have successfully provided power to the back of my house from the car V2L. Managed to wash a basket of clothes and tumble dry, all while fridge, freezer and kettle were connected to same powerboard. Boiled water while on soak cycle of course. I used 6 kwh over 5 hours. I'd like to keep these...

    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...

    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...
