Problem with video player

Hi experts,

I'm under 2 problems with video player in my application:

1. the backlight turns off automatically after 30 seconds by default during playback of a video file.

2. impossible to adjust the volume, he always plays with the highest volume.

When I try to play the video by media player integrated BB Bold, the volume is adjustable and the backlight is on during the display of the video. Is it possible to do the same thing in my application?

Thanks in advance,

Kind regards

Binh Nguyen

-For the first problem, you will need to set the backlight to yourself in the code, something like:

If ((Display.getProperties () & Display.DISPLAY_PROPERTY_REQUIRES_BACKLIGHT)! = 0)
{
Backlight.Enable (true, 20);
}

Be careful about the number of seconds that you pass to the enable(). They are tp limited 255 seconds even if you spend a lot. This means that if your video is longer than 255 seconds, you must call the activate more than once. I usually call it the timer as well as check the status

-For volume control, the player does not meet the default control buttons. You need to implement it in your code.

Set the class of player that you use to implement the method as follows:

  protected boolean keyControl(char c,int status,int time)
    {
        if(c == Characters.CONTROL_VOLUME_UP)
        {
            //IncreaseVolume;
        }
        else if(c == Characters.CONTROL_VOLUME_DOWN)
        {
            //decreaseVolume();
        }
        return super.keyControl(c,status,time);
    }

Where the increseVolume is something like:

If (_Kit! = null) //_vc = player VolumeControl
{
_vc.setLevel (volumeLevel);
}

    Problems with media player 11 and all other players, playing music is broken?

    Hi all

    I have a big sound even and odd / problem reading music?

    My computer using windows media player 11 and classic media windows and others to play my music in the hard lists recorded by windows media player 11 copied from my CD.

    But here's the weird problem that only started to happen now, when I play music saved on any one of the players of the computer the sound breaks sometimes but not always?

    Even if I try tp use players like windows media player 11 to play recorded video clips sound breaks toward the top, but the video image only?

    I have a newly completed with windows xp home system and service pack 3, and all memory and material necessary for a pc game of level, a new graphics card was installed and by the way the problem of noise was there before this was done?

    I don't know what is the fault? And I don't know how to find out what the required audio driver are for his computer system I?

    I tried the right click on the audio device to see if the pilot could be updated in case that's all? All he asks is a cd or a floppy disk, but I thought you could ask to search for drivers online too?

    He even now breaks the game sounds too!

    Help, please

    If you access Windows Update (start - programs - Windows Update), you can
    see if there is a newer driver. The drivers are optional updates are not so made
    automatically.
     
    Download the driver for your audio hardware manufacturer (or motherboard if
    "It's built-in sound). They are often newer than Windows Update.
     
    This explains how to disable the improvements.

  • Problems with video recording

    Hello

    I have some problems with the video recording on the BlackBerry.

    On the BB 9700 my application crashes when I try to stop recording. The file produced
    the app is empty.
    On BB 9800 I have the same problem unless I have explicitly defined the video resolution, but

  • Problems with video previews: Picture freezes during purification (CS6)

    I just installed CS6 on my computer after working with CS5.5 and I met a strange problem with my EOS5D Mk 2 and also Ixus 100IS images in Bridge CS6 (in fact, this happens with all videos).

    In CS5.5, I could get a glimpse of my mov files and rub through them without many problems (apart from occasional, but good crash... )

    In CS6 now the preview of the video starts and everything seems fine, until I have rub to a point later in the video. At this point, the video freezes but the sound continues. The only way to make the video running again is to click pause and then click play again. You can imagine that rub through videos is not fun...

    Someone at - it already had a problem like this with CS6?

    Since CS5.5 is always installed, I checked and found that in CS5.5 bridge everything still works fine: no video freezes it - only in CS6

    I've already updated the latest graphics card driver and all updates cs6. Does anyone have an idea what I could do?

    some stats on my computer:

    Win7 64 bit

    NVIDIA geforce GTX 590, pilot 301.42

    no other video software installed

    Aside from that, I also realized that the video quality in the preview area is not particularly brilliant (in CS5.5 or CS6). Because the video is proportional to the size of the preview window, I sometimes get artifacts/moirees scale. Is there a way to smooth video playback, as you would in a regular video player?

    Yes, this is a known bug.  I found it in beta, Adobe has confirmed, and they should have a fix on the next dot (hopefully) release.

  • HP Slimline problem with video card?

    Hello

    I got a Slimline s3020n for a few years and have never had a problem with it. A few days ago when I turned it on there is no picture on the monitor except the box that is displayed when you turn it on and it says: "no signal". I plugged into another computer to the screen to see if the monitor was the problem and it worked fine. I swapped the hard drive thinking that might work, but still had the same problem. All lights turn on and it seems that everything works (hard drive, fans) which leads me to think, maybe it's a problem with the video card. My question is if you have advice on what could be the problem and I think that the video card is integrated into the motherboard, so I have to replace the whole motherboard to fix this. Thank you.

    -Chris

    Chris,

    Your PC has built-in video on the motherboard.  If it is simply a matter of graphic, a low profile card could be added to the system.   However, you can view the following link - depending on when you purchased your product - you may qualify for an extended warranty - the problem, he describes sounds similar to what you mentioned.  I found this on the page of the product of the s3020n, btw.

  • Problems with media player and Streaming Online & Essentials

    I didn't know where to post this because it concerns problems reading media downloaded and all media and streaming online. In other words, any media. I have now found my problem with the problem and that's coming from MS Essentials and becomes very disruptive. Carefully One I've ever had this problem and it's probably because it was not a free service, however, since I installed essentials the problem has worsened. Also on one of my computers, the update will start just randomly and all but shuts down the system. Yet once, never happened with care. If this problem persists I will launch essentials to another more compatible antivirus protection system. Moreover, it happens with all other types of media also like Real Player and i Tunes so it is not exclusive to WMP.    All resolutions to this problem would be greatly appreciated. Thank you

  • A very strange problem with DVD player (some DVD play not)

    Hello everyone.

    I bought a laptop Dell Inspiron 3543 2 months ago. Overall, I am very satisfied with this product, but I have a problem with the DVD player. When I insert some DVD discs, the driver reads some DVDs but not others. After trying to play DVDs, I see that the DVD player play about half of the DVD I'm looking for. Although I can guarantee, I didn't send my laptop to the service because I can't work even a day without my cell phone. So, in order to solve the problem, I bought a DVD player new, original Dell (the same model of dvd player, which is Panasonic Matshita DVD +-RW UJ8E2). Today I started using my new DVD player, but it also has the same problem as my old DVD drive or it also does not play some DVD.

    To make the issue even more strange, here are some details:

    -My dvd drives have no problem and I have tried many original DVDs (especially the original films). And all the dvd disks that do not play on my computer play on other computers with no problems. There is no problem with the disks.

    -Certainly no problem with the "DVD region Code". I use original DVDs with region code 2, which is the area code for my country.

    -All my drivers, the operating system and the dvd drive drivers are up to date. When I look at my DVD drive properties, it is written that "the dvd drive works properly.

    -When I insert a DVD disc, if my DVD player he plays, he plays each time. But if my dvd player does not play a dvd, and then he never plays it. So, there is a consistency in the dvd disc set to play or not. When a DVD disc does not play, my DVD player rolls the drive some time and then the DVD done pretending as if there is no disc in the drive.

    -Both my old and newly purchased DVD drives have exactly the same problem, so I think that there's no problem like a lens dirty. I also think that there is no mechanical problem with one of my DVD drives because my newly purchased, original DVD player also has the same problem.

    I thank everyone for any help or advice in advance.

    Today, I received my dvd player third, new, Chinese, not original from a seller of spare part. He plays all DVDs with no problems. :)

    If in the future someone always has the same problem as me and read this Web page to find a solution, you know where is the problem.
