    hello, I’m developing a mobile application. HTC currently have a 3.0 MegaPixel. I used your dll and I am very pleased with their use. But like everything else I have a little problem: (will not let me change the resolution to 240×320 for better. SetMediaType I have used for this, but when I try to setearlo May-zero number, my application fails. Now, there is a way for using This library allows me to work at a resolution greater than or equal to 640×480.

    Thanks and I hope your answer.
    Greetings

    Hi, Im a beginner but I have successfully managed very well with your DLL. I am using it on a standard Windows Mobile 6.1 phone and everything works. Except the preview image is upside down. I compiled up your example and the preview image there is also inverted. But I cant seem to find a way to invert the image back. Sorry if its a silly question but have I missed something?

    All help greatly appreciated.
    Thanks
    Richard

    version 1.1.3.0:

    1. AMCamera now text draws after target (so target wont be drawn over text)
    2. AMCameraEx memory leak fixed
    3. AMCameraEx fixed bug “ConnectGrabberError_2″, now class should
    work correct on all devices
    4. AMcameraEx fixed conversion from RGB565 to RGB24
    5. AMCamera fixed drawing text on RGB565
    6. AMCamera fixed conversion from YV12 to RGB565
    7. AMCameraEx edded Edge Detection effect

    P.S. Tested on Samsung i710 and Toshiba Portage G910

    CarlB, you can always build simple DirectShow graph and check that image rotated on some devices, so if its bug, then it definitly not my.

    you can always check frame returned by GrabFrame and see is it screenshot or not. Also you can read SampleGrabber docs and you will find answer for question regarding “screenshot”.

    P.S. if you need some custom features use email or skype instead commenting…

    Thanks for your reply… the “need” for rotation ist nor the problem… I wouldn’t need it, when the video would be correct in the panel. even your samples are showing the vide rotated. so it’s not a missing feature, it’s a bug.

    I promis, I’ll buy your sources if it will work correct… or let’s make it short… waht would it cost to correct it? I dont need the sources, I need only the ability to show the actual video to the user (with overlay) and grab some images while the preview is shown.

    btw. return the GrabFrame-method a “screenshot” from the preview or does it deliver a “real” image (640×480) for example?

    Hello ,
    First of all …
    Thanks for your master piece !

    I got some problem on this …
    Is that possible to get the progress position in the player ?

    Thanks again ~

    admin Says:

    2CarlB, I can implement rotation, but i dont have enough time to do it, so if its so important for you, you can always buy sources and do it for you needs.

    BTW panel or any other control using for rendering, not for capturing
