Videos show no image in OS 7

Hello

I have an application accessing a service to download videos on the phone and play them later. This application has been tested up to OS version 6.

Now I test if it works under OS 7 (I'm testing with the Simulator 9930 BB) and I find that the video does not appear, but the sound can be heard perfectly. In previous versions the video read without any problems at all, so that the OS 7, the screen shows just a black screen (during playback). This same behavior can be seen on a real phone.

To play the videos, I use the standard way, i.e.:

_player = javax.microedition.media.Manager.createPlayer (_videoUrl);
_player. Realize();

_Kit = _player.getControl ("VideoControl") (alarm);
Field videoField = _vc.initDisplayMode (Field) (VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field");
_vc.setDisplaySize (Constants.BBWIDTH, Constants.BBHEIGHT);

Later, the "videoField" field is added to a Manager, who in turn is added to the screen.

I tested the video and audio formats, but it seems to be compatible. Also, I don't understand why it might work correctly the OS 6, but not the 7 OS.

Any help?

Thank you

After struggling with him a few days, I finally solved it.

The key was in the code that was setting the size of the field for the VideoField: he read these values in the VideoControl object. For some reason, it worked on OS 6 but it was returning (0, 0) OS 7. This is the reason why he did not display the image of the video (duh...).

Adjusting the size according to the size of the screen solved the problem.

  • Prime Minister - imported videos show slow images, audio plays perfect

    Hello!

    I recently stumbled on this after a reinstallation of my system. I have Pro CS4 first (with the latest updates, tried without updates as well) and the 64 bit version of Windows 7 (completely up to date).

    Here's the deal:

    After I created a new project, I leave everything intact, select only 1080 resolution NTSC (or PAL). I have imported video clips (has each audio and video clip), I want to work with. This import is fast and not mistakes... but when I really want to work with clips (for example: double click to start at the edge he or dragging to the timeline) what is happening:

    Audio play perfectly... but the video is like 1 images / 60 seconds or more. While the audio is just fine video plays really slow almost like a support of still images. And so, the length of a video on the timeline is correct the audio, but I get not even 4-5 frames of fotage video before the end of the clip. To sum up: video and audio is really out of step, but in a weird twisted way. Audio OK, increased or reduced speed is detectable, but the video (same btw) is not like that. He shows me some pictures before the time of the end of the clip.

    Is this a problem with the import?
    If yes how to correct?

  • Recorded video appearing differently - image format?

    I use Premiere Elements for about a year and move to the EP 14 in March.  I still feel like a novice and cannot explain it clearly.  I hope my video attached.  I had no problem with PE until this last week.  What I see on my screen when I'm editing in PE, isn't what makes its appearance in my final video output.  If I put all images on my second piece, the final video shows these images with black lines on the sides, even if it appears in PE.   I've never had this problem before.  What has changed?  Or what I am doing wrong?   Since it's really hard for me to explain it, I share a video of the final video: what means MK NEW2 - YouTube

    Thanks for any help.

    Its a little bit of everything.

    Your export settings are in high definition, while the project settings are in standard def. where the strange appearance.

    I would put up a widescreen DV project. Turn off the power of the scale to the size of the image in the preferences.

    All manually adjust and export to dv wide screen or widescreen dvd.

    Then reset your preferences - with Photoshop CC you can do it in the preferences. Earlier versions require that you press the modifier keys that you launch Photoshop. Ctrl alt shift on Windows or cmd opt shift on Mac.

  • Video shows that in the margin of safety

    I really hope I don't have to repeat everything I just edited. So I hope you guys have an answer for me.

    The problem is that Ive made a video that contains images and the resolution of 1920 x 1080 live video. The video begins with a 720 p picture and then continues in 1080 p video. What I don't understand is when I have exported it in the same format as I always do. The video shows what is in the margin of safety. What happens because I managed to move a picture from the video "off the screen" somehow?

    And if you manage to do it, is there a reset button, so we're back in the 'frambox' or whatever you call it.

    Out in the video Ive used the pan / zoom feature, has something todo with the video showing just what's inside the margin of safety?

    When I started the project I didn't select new. I just opened the program and began to add photos and videos.

    IM exporting the same type every time, which is Adobe flash video and 1080 p F4V - HD. That has always worked well for me and I have not had this problem before.

    Jiinxs

    Thanks for the follow-up.

    That present you your workflow, p60 of 1920 x 1080 video and image 1920 x 1980 and with those export settings, I have is only with the export settings

    frame rate defined as identical to the Source, as I mentioned earlier. But that should not contribute to your export 1472 x 832 F4V get.

    If you do not already have it, you can try once more with this project. This time, import your video and photo, but don't do any pan and zoom, then

    Let's wait and see what looks like the export as well as what are its properties.

    After exporting F4V, where you see this description 1472 x 832 for your export to F4V?

    Please consider. We will be watching for further developments.

    Thank you.

    3. you will remember to do recent changes on the computer before this problem?

    If you use Windows Live messenger, you can consult the following articles and check if that helps:

  • Show-hide images (or group)

    Hi all

    I have a question: How can I use the same button for sho and hide something?

    Example: I have a photo (A) and I want to show another image (B) when I click photo's and to hide B once more, when I re - click.

    Ho can I do?

    I've created a transparent form that appears on A first click, and I use a tip action that allow this transparent form to disappear when I click on it. And Yes, the circle will start again. But I want to do that, I want to put the above writing (with only 2 foto, A and B)

    I would use a shared conditional action. You need a user variable to track

    What image is visible, this tagged as v_second, with a default value

    0. This means the second image is not visible, will be toggled to 1 when it is

    visible. Action will look like this:

    IF v_second equals 0

    Hide Im_a

    See the Im_b

    Toggle v_second

    ON THE OTHER

    Hide Im_b

    See the Im_a

    Toggle vsecond

    If you opt for a joint action, the two images will be settings.

    Image can be replaced by group or something else when you apply the shared

    action.

  • Link column shows no Images

    Hello

    I have a classic report with a column like this:

    It works very well.

    What's wrong?
