    well, I managed to make a mess of the code but still no closer to having the overlay on the video.
    I did update the support classes with newer code available on the project page but that didn't help on adding overlay
    We need someone with above intermediate knowledge of directx/directshow to look at the code and make the changes needed.

    So this is Windows only then? I thought I saw one around for Linux, was pretty sure it was this one. Is there a similar one that works in Linux?

    This is based on .net and I dont think the MONO abomination can run it so you wont be able to run it on linux.

    I expect to migrate the carpc to linux at some point in the next few months. If you find any good web cam video recorder for linux let me know. I already migrated my main laptop to fedora 10 and everything is working great.
    Check the linux sub-forum and the LinuxICE section

    Did you use the newer code on the DirectXCaptureRefresh project ( http://www.codeproject.com/KB/direct...reRefresh.aspx ) or the original project Prefect used. The refresh seems to be newer, but still doesnt look to have been updated since 2007. I was looking into learning C# (did Java for 4yrs at university) and trying to put it into a CF plugin when I started to get bogged down in all these different versions of the stuff! The most up to date I can seem to work out is to use the DirectXCaptureRefresh (which is on DirectShow.NET 1.5/VS 2005) and update it to use DirectShow.NET 2.0/VS 2005, which was last updated in 2007.

    At present I dont have a clue how DX works, but I like the idea of trying to get it updated, then into a plugin, and also get overlays working. With CF you can access the OBDII plugin which can give the nice overlay stuff like speed, rpm, etc.

    heres a link from when they tried to organize the project. I used the newer clases from the same project page. The refresh one didnt seem to have anything that could make the overlay any easier to implement

    I don't believe you can use SampleGrabber to modify the video stream. It's designed to decode a frame and copy it into a bitmap buffer which you can then do anything you want with it (detect commercials, video levels, save still image, etc.) but it's not really inserted into the graph like a true filter.

    Sorry, cant see a link

    With the newer DirectShow.NET on Sourceforge, they have examples of using SampleGrabber to overlay stuff. In one example they put a watermark onto the captured file and on another they read a file and overlay text onto it. The methods used in both look very similar, so I would guess you could use the text one with the watermark one to put text overlay into our captured video file. I thought getting it all up to date would be a good start then we can move from there on overlays and making it a CF plugin. I tried to just drop the newer DirectShow.NET dll into the Refresh project but it doesnt run, so I guess they changed some function calls between v1.5 and v2 which is a shame, I hoped it would be drag and drop. Doing a diff on the CaptureTest of refresh and the Capture! program code, they look very similar and I think the Capture! one can be dropped straight into the Refresh. I will test that tonight and see if it compiles/builds.

    I should never skip preview when posting......
    heres the link:

    Inserting the customized CaptureTest into the captureRefresh project would be the easiest way. I though about doing a diff between the original CaptureTest and prefect's CaptureTest to extract the changes. Then it would be a matter on inserting the code in the correct places in the CaptureRefresh class without having to worry too much about the rest of the code. Prefects customization deal with the form design and file handling mostly so they wont get affected by any function changes in the video capturing methods.

    Cool, thanks.

    I was bored at work yesterday and was doing diffs between various versions. I think all Prefect changed was the actual CaptureTest class when he updated it. I'm sure he said that somewhere in this thread about doing all his changes in the main class and it was messy. The differences between the original CaptureTest and Prefects CaptureTest are the same differences between the CaptureTestRefresh and Prefects CaptureTest, so integration should be a simple drag and drop.

    I have a track day coming this weekend and new seats delivered tomorrow, so cant see I will make much progress the rest of this week, but definately will try and stick Prefects CaptureTest class into the CaptureTestRefresh.
