    I hvae 8 days to finish before my trial of video libary is gone



    So about vista if registring xvideo doenst help then i hvae no idea why that doenst work. I still didnt get to installing vista here yet



    As to the sounds for recording, yep will add them, also I'm thinkong to add images that will indicate the recording status (unfortunatly i can not have transparant images



    Detecting reverce speed by gps is not posible by software only unles you are moving on one way street and ur map tells u that. oterwise gps always thinks u r going foward. However if you can attach Phidgets board to your backup light I can detect that you are moving backwards and show you backup camera full screen. (If you will me to add support for that i can do that a bit later)



    As to the multiple cameras, that is doable but needs quite a logic to control everything. How about I get all the other parts working and then i add supports say for 8 cameras? That should be enough for all ppl (Real Car DVR) well then u will need real good car PC to get some fps.



    Um, sounds like I ill have to buy the damn library

    Any one goes for donations ;-)

    well drop thye forwards/backwards if you are able to do multi cam display ,thats enough.
    i only want 3 cams really 1 forward 1 reverse and 1 in cockpit, 1st 2 i would like to be displayed in the same scr the 3rd is for somthing else i have in mind.

    how much is the libary , i'm willing to donate to this if you are sure you can pull it off, i know in the russian forum there is a cam plugin with 6 cams , and this is something i have been after for sometime now ,

    so hit me with the price

    what russian forum? I speak all languages anyway ;-)
    I can check what library they are using.

    Actually I like backup sensor part more as its easier ;-)

    Lib cost $200, but i'm not 100% sure if i will stick with it. So lets wait till the my trial expires and then i'll see how it goes.

    The problm with multiple cameras is that i have to do the GUI logic and thats getting messy 2 cameras to siplay is more or less ok. I think I can do screen sptoter and positionong w/o getting dirty

    3rd camera on separate page if needed.
    PS: hey stop spying on your passangers :P

    Hmm 2nd window may be a problem for RR overlys... I guess I have to have invisible window for it

    which file am i supposed to register..? i can't find "xvideoocx.dll"
    the only dll's i found in the zip are "Interop.XVIDEOOCXLib.dll" and "AxInterop.XVIDEOOCXLib.dll"

    what i can do then is 1 app with 2 cams front / reverse , if it makes it smoother a button to switch between the 2 cams then only 1 cam is running at 1 time , but this will give another issue switching time , the time it takes to switch cams from front to back .

    then a single app ( as is now ) for the 3rd cam as its use will have nothing to do with the car in motion.

    $200 so thats 130 uk mm not bad ,

    spying on passengers na not me lol......

    like you say lets see how far you can go without loseing what you have now, once i get
    my system back up and running and get off this PII lappy i can start to test this out .
    and just in case i'm xp through all my systems hate vista. good looking and some really good features but man its a hog.

    You need to register AxInterop.XVIDEOOCXLib.dll
    But If it has Interop prefix that menas you are looking at the unextracted source files. So you need to run the installer first if there is no errors you have to search your comp for XVIDEOOCXLib.dll and register that file. If you cant find that file try regitring both:

    AxInterop.XVIDEOOCXLib.dll
    XVIDEOOCXLib.dll

    technicaly they should be placed in the app root directory or in System32 directory.

    PS: I think library is using DirectX 8.1 and is that is the case I dont think vista has those files? I think vista only comes with DX9, 10 files so that could couse the probelm too

    Carputer1, its most likly be one single app with all features in it. I'm if i'll have multiple project i would have hard time fixing bugs in all of them

    I will try to get first 2 camera version soon, but i'm geting time issues and after all i have to make money for leaving too ;-) and i spent last 4 days onlyt doing this thingie

    any way;

    fror now the schedule is following:
    1. add GPS overlys from RR
    2. add GPS log file
    3. add 2nd camera support
    4. add direct GPS connection possibility
    5. add GPS + Video Player to see both map and video on the same screen for videos that we recorded with the camera
    6. add external config utility so u dont hve to mess with .ini file that is 20 lines of setings and mos likely to grow 300 lines
    7. Check if it is suitable to go to better lib
    8. get some menety and translate it to C++ project for better speed (I dont do C++ myself so i will have to hire some one)

    about the multiple cameras, you could take the multiple videos combine them on the video buffer and then display and save one video. Then you could have hard coded values for the video displays arrangement
    full size for one video
    50% side by side for 2 videos
    25% 4 cell grid for 3 or 4 videos
    etc...

    are going to make the source code public?

    combining video in one stream is not possible in the curent libary nor i really se any resons of doing that as i would have to increase the resolution and that would drop your fps unless u got MMX 3 capabilities on ur PC... Most via mobos dont use MMX and VIA is most popular carpc mobo... so id rather stick with separate streams.

    As to the code, sorry i'll keep it private for now as it is hot thingie and our company in direct business of mobile security so i cant release it.
