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.

    First 'away from home' charging and V2L working in anger

    Well, the MG is out of the garage, still broken, but we got bored of waiting for the dealer not to fix it and decided to take it on a trip to Spain as I'm working at the Barcelona circuit this weekend taking polaroids of race cars going round and round in circles turning hydrocarbons into noise...

    Using V2L to keep electricity bill lower

    Before i start, please note that i do not currently own a ZS EV, so this is just speculation, not me trying to "cheat" So, like everywhere else, electricity prices are skyrocketing in Denmark. The current record was a few days ago, where the price from 7-8PM on a cloudy day with not much wind...

    V2L adapter

    Hi I'm just wondering if any of you who have received the Marvel r, did you also get the V2L adapter? I'm asking since most of the YouTube reviews said it would ship with one. I did not receive one so I would like to know if I'm the only case or they changed their mind about including it.

    V2L - useful ?

    That's what I was alluding to Michael. For true V2H or V2G you need (amongst other things) circuitry to synchronise the output AC waveform with that of the grid/house supply.

    V2L warning - also discharges 12v battery!

    So first time using our new V2L cable on the campsite last night and awoke to a flat 12v battery. It seems that with the V2L cable attached there is some form of drain on the 12v battery although I cannot work out what or why?! The process we followed was: car on, discharge screen set to 40%...

    New ZS ev V2L options

    Whole I wait for my new LR Trophy Connect to be built, shipped and delivered (I can dream) I was thinking about the vehicle to load function. At present it seems that it can only be used when the vehicle is not being driven and the lead is outside the vehicle. The Ionic5 and EV6 both have a...

    V2L cable

    Hi all. I searched up here and online and the only place really that sell such a cable is evcable website. But that is still at a whopping £150 for a 5 m cable single gang. Is there anywhere that does one that is a bit more price friendly ? I have to do quite a few camping trips to make the...

    Marvel R V2L

    V2L (Vehicle to Load ) is the most exciting thing about the new Marvel R for me. I expect that I will probably be alone in this so let me explain. Once you have an EV it makes a lot of sense to make your own fuel at home from Solar. I have solar and batteries, I make all my power for my car and...
