Programming of camera of black berries

I want to take pictures using the camera of black berries for my application, it is possible in version 5.0 and yes then how?

Yes, it is certainly possible, but is not a very simple task if you do not get tips at the front.

First of all, there is an example of code that comes with the package Eclipse at least (CameraDemo) that shows how to create a viewfinder using a field, player and VideoScreen. The biggest problem is that third-party developers can't stack anything on top of the viewfinder (that's where they call the domain after you put as such with an alarm.

In addition, you're very limited to what the size, you can define the field - I only got half of size and work full screen, some dimensions got ignored and others led to not display at all.

Here is a code that says this:

_videoField of private sector;
Private player _player;
private VideoControl _videoControl;

private void initCamera() {}
try {}
_player = Manager.createPlayer ("capture://video?? Encoding = jpeg & width = 640 & height = 480");
_player. Realize();
_player.prefetch ();
_videoControl = (VideoControl) _player.getControl ("VideoControl");
_player. Start();
If (_videoControl! = null) {}

_videoField = _videoControl.initDisplayMode (Field) (VideoControl.USE_GUI_PRIMITIVE, 'net.rim.device.api.ui.Field');
_videoControl.setDisplayFullScreen (true);
Add (_videoField);
}
}
catch (System.Exception e)
{
view the error
}
}

After that, you can use

image of Byte [] = _videoControl.getSnapshot (sizeAndEncodingParamters);

o take the picture. To determine what sizeAndEncodingParameters your device supports, you can use System.getProperty ("video.snapshot.encodings"); which returns a String [] that you can iterate to determine what to use.

  • The program monitor keeps going black in first Pro CC

    PC - first Pro CC - AMD Fire Pro (13.101 - 130604 a - 158071E - ATI)

    I'm working on a project and the program monitor keeps going black in first Pro CC while I'm working on the script. I got like 28 GB of memory granted to the program and update the latest version of the driver for my graphics card. No idea why this continues to happen, but the only way I can get around it is to reboot. When I go to close the program hangs and I have to stop it in system preferences.

    Under a crazy period if you can help? Thank you

    Hi Jonathan,.

    We have not seen a response from you because you have created this thread. Please let us know if you have solved the problem completely. For others on this thread, a few things were useful to solve the problem of 'black screen '.

    1. If your computer is underpowered and outdated (especially your CPU and GPU), he will expose the problem of 'black screen '. Consider upgrading your components or by switching to a newer computer.
    2. If your computer is newer and has components that are well within spec (core i7, 2 + GB VRAM for your GPU, etc) and you get the problem of 'black screen', it is likely to do with your GPU drivers or you have two GPUS and the Control Panel has the GPU badly activated for high quality graphics features. Control Panel for your GPU is probably pointing to the GPU to lower power of two.
      • Note that even if you have a considerably amplified GPU, it may be an old one that does not support drivers for a new version of OS X or Windows
    3. The GPU is problematic, in general. Choose file > project settings > general and set the converter to Mercury Playback Engine Software only
    4. Avoid the update to OS X 10.11

    Other workaround solutions include:

    1. Open the reference monitor: window > reference monitor
    2. Turn off the track (eyeball) power off, then on again. (Note: this may take a few tries)
    3. If you have already updated to OS X 10.11, OS X update to the current version
    4. Restore previous versions of video drivers video drivers
    5. Rolling back to a previous operating system
    6. Restoration of an earlier version of Premiere Pro

    I will mark this message as the correct answer and will add that other solutions users can have about it. Send me a PM if you think that your solution should be listed.

    Thank you

  • Programming of camera or 1744 with PLC

    Hello

    I have a N I 1744 camera. It scans the length and position of the pins. There are several lengths of pins. So, there are + 10 programs needed. The programs were made with NI Vision builder. The right program to fix the right axis is now inserted in the device with visionbuilder. I expect to get rid of the laptop and be able to choose the program with PLC S7-1200 installed. This would save some time.

    This would be possible or is there any otherway to make an easier selection of the program?

    Thanks in advance.

    If I understand correctly, you want the controller to tell what program to load the smart camera.

    Vision Builder AI support various industrial communication protocols which can be used to communicate with an automaton, like the series, Ethernet, Modbus, Ethernet/IP, OPC UA.

    You could also use e/s and send signals to the PLC to the smart camera.

    In the Vision Builder, select view > view complete on the inspection facility.

    Select then view > toggle main view window.

    On the left bar that is displayed, click the icon of the Inspection to select.

    Now click on the steps of Inspection: tab of the palette on the right to communicate.

    Select the step corresponding to the communication protocol that you have chosen to use with your PLC, for example, the TCP protocol.

    With this step, you want to read the command sent by the controller.

    Then go through the steps of Inspection: using tools additional tab scroll down and click on the select Inspection stage.

    This step allows you to specify which control to run according to the result of the stage of communication that you just inserted.

    Click Add to specify a new inspection. Specify a (value - Inspection) pair.

    Activate the checkboc 'Activate the selection of Inspection' and click OK.

    Go to the inspection of the VBAI mode and open an inspection.

    When control reaches the final State, the inspection status select will turn to see if a new inspection has to be charged.

    I hope this helps.

    Best regards

  • The program monitor randomly goes black

    First Pro CC uses for months and no problem.  All of a sudden, the program monitor goes black, then back over video transitions between clips, then goes black again.

    I have a HP workstation, with a processor of xenon 12-core, 32 GB RAM, 9 TB of disk storage hard (the first 1 TB flash), blazing fast dedicated with a ton of video memory video card.  It's worked wonders for 12 months and with all the other products Adobe (Photoshop, Lightroom) and hundreds of other programs.  I have NOT changed any video card or video processing settings.   I don't have a hardware problem - it is a problem with Adobe first Pro CC.

    I spent the maximum money on the hardware and the software more later/better (even though I hate paying a subscription for software).  And now this...   Moreover, I understand now and still not a bug, but when the screen goes black in a video software - well, it's like losing your direction while on the highway - it's sort of IMPORTANT - wouldn't you say Adobe?

    I'll scream at Adobe on Monday, but have a serious work that must be done this weekend.

    Is there any help that works?

    You use the latest versions (which numbers?) of Adobe CC?

    Try resetting the workspace.

    Try to update or restore your video driver.

    Try to remove the media cache files.

    Try resetting preferences.

  • All clips in my sequence of multi camera went black

    After spending a long time, editing a sequence of multi cameras, all the clips have now gone black. The waveform has disappeared, but the audio is not yet. Other clips on the same timeline, including another sequence mulitcam all seem to be good and I can't identify exactly where it happened in what concerns the measures I did.

    The last element in the sequence multicam has diagonal white lines through it. I don't know if this is related? Online forums suggest it's something to do with the insufficient media, but I don't really know what that means. The camera angle ends before the other, it's the only thing I can think of that would cause the white lines.

    I have attached some sceenshots I hope clearly the question - can anyone help? I'm desperate: I lost several hours of work! Thank you!Screenshot (1).pngScreenshot (2).png

    I have it solved! (With the help!) It turns out that the original source multicam file has been deleted. I was able to return to a previous AutoSave and import it into the current version of the project and add a link to my sequence for it. So relieved to have solved this problem without having to re - edit. Thanks again for the help!

  • Sequence of multi cameras went black (mostly)

    So, I edited three sequences of separate camera multi... They all was beautiful and I exported through media encoder. When I went to look at my files, one of the three was a really small size, and I noticed he was all black.

    I returned to premeir pro cc and of course this multi cam seqence was all black as well (except about 3 seconds of images in the middle of two different cameras). Now when I go back to the original (except the nested multi cam) sequence that is fine so I know that the clips are always linked in PP. Also, I can make a new cam multi of the original sequence and that is very good.

    I think that PP just F'd up... and unless someone can tell me how to go back in the file record history or something I'm flowing because first auto saved when I closed it last.  I'm seriously unprofitable as to why this has happened as it was fine when I went to export it... or at least almost immediately before.  Why are there 3 seconds of footage in the middle of all the sequences of black 47 min? and 3 seconds is from within a sequence of 10 minutes on the original UN nested sequence is not as if a single video file showing upwards.

    OK, so more about what happened that I want to spend my life with. Any way to copy edit them the points on a new multi cam sequence?  Does anyone have ideas, what's happened I can cancel?

    Thank you

    OK, so it's weird... so, the original UN nested sequence was 01:30 hours with 45 minutes of audio at the beginning unused. When I did my nested for multi cam editing sequence I selected the last 45 minutes and nested that.  Everything worked very well, but somehow during export it took my multi cam sequence and added within 45 minutes of audio virgins... so when I extended the sequence of cam multi at 01:30 there was all my videos... but my changes were all conducted on the top of the audio. Seriously stupid and certainly a bug!

    Is there an any file record history that I can come back?

    This looks like a bug in 7.0 that has been fixed in 7.0.1.  I recommend that you update to 7.1. In many if not most cases, the patch has corrected the problem in existing projects.

    Hi linsugr,

    Do you know when this started?  The simplest solution because I have no idea of what is happened to cause this is to restore the system to a point BEFORE this problem started (and give it a a few days to be sure).  If you use Windows 7, see:http://www.sevenforums.com/tutorials/700-system-restore.html. If you are using Vista, see:http://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/. If you are using XP, see:http://www.bleepingcomputer.com/tutorials/tutorial56.html.  If the first attempt fails, try to go back a little further and see if you are met with success.

    I hope this helps.

    Good luck!
