  • SurfaceView for Camera Preview won't get destroyed when pressing Power-Botton

    - by for3st
    I want to implement a camera preview. For that I have a custom View CameraView extends ViewGroup that in the constructor programatically creates an surfaceView. I have the following components (higly simplified for beverity): ScannerFragment.java public View onCreateView(..) { //inflate view and get cameraView } public void onResume() { //open camera -> set rotation -> startPreview (in a thread) -> //set preview callback -> start decoding worker } public void onPause() { // stop decoding worker -> stop Preview -> release camera } CameraView.java extends ViewGroup public void setUpCalledInConstructor(Context context) { //create a surfaceview and add it to this viewgroup -> //get SurfaceHolder and set callback } /* SurfaceHolder.Callback */ public void surfaceCreated(SurfaceHolder holder) { camera.setPreviewDisplay(holder); } public void surfaceDestroyed(SurfaceHolder holder) { //NOTHING is done here } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { camera.getParameters().setPreviewSize(previewSize.width, previewSize.height); } fragment_scanner.xml <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <com.myapp.camera.CameraView android:id="@+id/cameraPreview" android:layout_width="match_parent" android:layout_height="match_parent"/> </RelativeLayout> I think I have set the lifecycle correct (getting resources onResume(), releasing it onPause() roughly said) and the following works just fine: pressing home and returning pressing Taskswitcher and returning rotation But one thing doesn't work and that is when I press the power-button on the device and then return to the camera-preview. The result is: the preview is stuck with the image that was last captured before button was pressed. If I rotate it works fine again, since it will get through the lifecycle. After some research I found out that this is probably due to the fact that surfaceView won't get destroyed when the power-button is pressed, i.e. SurfaceHolder.Callback.surfaceDestroyed(SurfaceHolder holder) won't be called. And in fact when I compare the (very verbose) log output of the home-button-case and the power-button-case it's the same except that 'surfaceDestroyed' won't get called. So far I found no solution whatsoever to work around it. I purposely avoid any resource cleaning code in my surfaceDestroyed(), but this does not help. My idea was to manually destroy the surfaceView like asked in this question but this seems not possible. I also tested other applications with surfaceViews/cameras and they don't seem to have this issue. So I would appreciate any hints or tips on that.

  • audio power on AudioQueue

    - by Tomoyuki
    Hi everyone. I'm now creating an Application using speech recognition.To check the Audio Power coming in through the microphone, I wrote a method as follows. -(void)checkPower(AudioqueRef)queue{ UInt32 expectedSize= sizeof(AudioQueueLevelMeterState); AudioQueueGetProperty(queue, kAudioQueueProperty_CurrentLevelMeter, audioLevels, expectedSize); NSLog(@"average:%f peak:%f",audioLevels.mAveragePower,audioLevels.mPeakPower); } I found that sometimes mAveragePower was larger than mPeakPower, and when mAveragePower was 1.0, in other words, averagePower is regarded as max, mPeakPower was lower than 1.0. I think that generally this result is inpossible. please Let me know if you have any information about sound power on CoreAudio. thanks.

  • Hyper-V Deployment Options Best Practices

    - by Erv Walter
    In what circumstances would you choose each of the following deployment options: Hyper-V installed as the bare bones Windows Hyper-V Server 2008 R2 Hyper-V role installed on a Windows Server 2008 R2 Server Core installation Hyper-V role installed on a Windows Server 2008 R2 Full Installation For example, I know there are licensing considerations for each option: With Hyper-V on top of a full installation of Enterprise or Data Center edition, you can use Windows Server as a guest OS without needing additional licenses (4 for Enterprise, unlimited for Data Center) With "Windows Hyper-V Server" you have to obtain licenses for each guest OS. But my real question is, are there technical considerations as well? I understand that the Full Installation doesn't perform as well as the other two options, but is there a significant difference between Server Core and "Windows Hyper-V Server"? What are the pros and cons of Hyper-V on Server Core vs "Windows Hyper-V Server" and when would you choose each?

  • HP Recovery options: System Recovery not showing

    - by sha404
    I am using HP Pavilion dv4 notebook. Previously, there were following options in Recovery Manager(using f11 during boot): +System Recovery +Factory Restore +Minimized Image Recovery The System Recovery option allows me to restore only Operating system drive e.g. C:\ drive, keeping all other user (me) created hard drives intact. I made a set of recovery disk. Since then I don't see the System Recovery option in HP Recovery Manager. But all other options are still there. But when I use recovery disks that i created earlier, that option e.g. System Recovery is shown. But It's really boring and time consuming to use disks for recovery. So, what's the problem with internal HP Recovery Manager? Why isn't it showing that option?

  • ClearMyTracksByProcess - all options?

    - by Jonny Blaze
    I've seen the list of values floating around the internet for ClearMyTracksByProcess Delete Temporary Internet Files: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8 Delete Cookies: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2 Delete History: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 1 Delete Form Data: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 16 Delete Passwords: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 32 Delete All: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 255 Delete All + files and settings stored by Add-ons: RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 4351 But it's not a complete list of all the options, and I can't seem to find a complete list (whether there isn't one published, or this one has been republished too many times and is hogging all the search results, I'm not sure). What I'm looking to do is delete Cookies + Temp + Add-ons, but preserve History, Form data, and Passwords. Has anybody found a complete list of all the available options? Or just the option for Add-ons so I can do the math myself? (e.g. Add-ons value + 8 + 2 = the answer I'm looking for) Thanks for looking at my question!

  • Entering Unicode Characters using NumPad in Chrome conflicting with Options Menu

    - by YatharthROCK
    TL;DR: Can't use E while entering Unicode on NumPad — conflicting with Options menu OK, so I finally got entering Hex Unicode chars on my laptop using the NumPad working using this answer from this link But when I was trying to enter the Irony Mark (? U+2E2E), as soon as I hit the E, Options opened up like in old-style menus where pressing Alt + letter brought up the relevant menu. This annoying behaviour doesn't let me enter any Unicode code-point that has an E. This works fine outside Chrome. How can I stop this?

  • Options for gaming remotely on a LAN?

    - by Schwern
    I have a Windows 7 desktop for gaming, a big bulky tower with a nice graphics card. I'd like to sit out on my porch rather than inside while the weather is nice and play games. I have a high end Macbook Pro. What are my options? I figure either remote desktop over the LAN on the Macbook or maybe wireless video, keyboard and mouse. Something so I don't have to physically move the PC. The sort of games range from things like Skyrim to SW:TOR to Torchlight 2. What are my options? They have to do a better than running Boot Camp on the Macbook (MacBookPro8,1 i7 2.7 Ghz but Intel Graphics 3000). I realize there's a lot of issues involved in running a game over a remote desktop with a decent frame rate, I'm interested in a practical answer with real experience behind them. Ideally something that works on a OS X so I don't have to reboot into Windows.

  • ESXi 4.0u1 - backup/copy options

    - by Hanadarko
    I have a machine built using ESXi 4.0u1 and it has 3 hard drives. I have my hosts built on different hard drives but wondering about backup options. I do not have RAID but I have 3 drives and 1 is totally empty. I had been using it to store ISOs for loading. So what options do I have to either create a 1 time copy onto the spare drive or some sort of snapshot to the spare drive? - There must be some way to do this either via the vsphere client or ssh into the ESXi box and go from there. Thoughts? -JD

  • Script to set "Hide file extensions"

    - by Ickster
    I'm tired of the multi-step process to set my preferred folder options on every server to which I log on (Mostly Win2008, but also some 2012 and Win7 here and there). I'd love to be able to script the process, but unfortunately, I can't find any commands or extensions to do so for folder options. There are several settings I'd like to change, but in particular, I'd like to set "Hide file extensions for known file types" to false. I figure that if I can do that, I'll be able to manage any additional settings on my own. Methods that work on the vanilla command line would be preferred, but if there are commands in PowerShell, I'll use that.

  • How do I start mysqld with options

    - by xiankai
    I need to start up mysqld with command line options as from here: http://dev.mysql.com/doc/refman/5.1/en/server-options.html#option_mysqld_skip-grant-tables I normally do sudo service mysqld start, but passing the option as sudo service mysqld start --skip-grant-tables does not seem to work. Alternatively I have tried starting as a daemon, sudo mysqld_safe --skip-grant-tables & But it seems to terminate too soon: 131101 04:59:57 mysqld_safe Logging to '/var/lib/mysql/vagrant.example.com.err'. 131101 04:59:57 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 131101 05:00:03 mysqld_safe mysqld from pid file /var/lib/mysql/vagrant.example.com.pid ended My last option seems to specify the option in /etc/my.cnf instead, but is there any way to do it via the command line?

  • SQL Cluster install on Hyper V options

    - by Chris W
    I've been reading up on running a SQL Cluster in a Hyper V environment and there seems to be a couple of options: Install guest cluster on 2 VMs that are themselves part of a fail over cluster. Install SQL cluster on 2 VMs but the VMs themselves are not part of an underlying cluster. With option 1, it's little more complex as there's effectively two clusters in play but this adds some flexibility in the sense that I'm free to migrate the VMs between and physical blades in their cluster for physical maintenance without affecting the status of the SQL guest cluster that's running within them. With option 2, the set-up is a bit simpler as there's only 1 cluster in the mix but my VMs are anchored to the physical blades that they're set-up on (I'll ignore the fact I could manually move the VHDs for the purposes of this question). Are there any other factors that I should consider here when deciding which option to go for? I'm free to test out both options and probably will do but if any one has working experience of these set-ups and can offer some input that would be great.

  • Taming XCode’s auto-complete options

    - by Nippysaurus
    I am fairly new to XCode and the Objective-C language. When I am instantiating a class, for example an NSMutableArray, XCode will provide a whole lot of auto-complete options. Even for an empty class which simply extends an NSObject has many options, most of which seem completely useless. What is the reason for having so many auto-complete options, or can they be "tamed" in the preferences?

  • Command-line options for HH and opening CHM Windows Help Files

    - by Jeromy Anglim
    I'd like to be able to write Inquisit scripts in Vim. In the standard Inquisit application for writing scripts, I can press F1 and it brings up help on the topic related to the word under the cursor. I'd like to set up the same functionality through Vim. The help file for Inquisit is stored in a Windows .CHM file. I figured there must be a set of command-line options for doing a keyword search in a chm file, but I haven't been able to find a complete list of the command-line options, presumably for HH.exe. I did find this page with a few pointers, but it does not have a full listing of command-line options. I also found this discussion on AutoHotKey discussion board. It mentions keyhh. I also just found a vimscript designed to do exactly what I want Questions: Is there a complete list of command-line options for HH.exe? Is there a better way of going about what I am trying to do?

  • jQuery UI datepicker options as varialbe

    - by Desmond Liang
    I have a number of inputs on a page function as JQ UI datepicker. Each needs to have different settings. I want to minimize the JS so I save the settings as an attribute in each individual . <input type="text" class="datepicker" name="dateofbirth" id="dateofbirth" size="20" value="" options="{ dateFormat: 'yy-mm-dd',changeYear: true,yearRange: '1920:2010'}" /> <input type="text" class="datepicker" name="expdate" id="expdate" size="20" value="" options="{ yearRange: '2011:2020'}" /> I use js to load the options dynamically as the settings. $(document).ready(function(){ $(".datepicker").each(function(index){ $(this).datepicker("option" , $(this).attr('options')); }); }); datepicker is not functioning. If I empty the parentheses after $this.datepicker it works fine. I have also tried another way to assign settings. ("option",...) no dice.

  • http post request with cross-origin in javascript

    - by Calamarico
    i have a problem with a http post call in firefox. I know that when there are a cross origin, firefox first do a OPTIONS before the POST to know the access-control-allow headers. With this code i dont have any problem: Net.requestSpeech.prototype.post = function(url, data) { if(this.xhr != null) { this.xhr.open("POST", url); this.xhr.onreadystatechange = Net.requestSpeech.eventFunction; this.xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8"); this.xhr.send(data); } } I test this code with a simple html that invokes this function. Everything is ok and i have the response of the OPTIONS and POST, and i process the response. But, i'm trying to integrate this code with an existen application with uses jquery (i dont know if this is a problem), when the send(data) executes in this case, the browser (firefox) do the same, first do a OPTION request, but in this case dont receive the response of the server and puts this message in console: [18:48:13.529] OPTIONS http://localhost:8111/ [undefined 31ms] Undefined... the undefined is because dont receive the response, but the code is the same, i dont know why in this case the option dont receive the response, someone have an idea? i debug my server app and the OPTIONS arrive ok to the server, but it seems like the browser dont wait to the response. edit more later: ok i think that the problem is when i run with a simple html with a SCRIPT tag that invokes the method who do the request run ok, but in this app that dont receive the response, i have a form that do a onsubmit event, i think that the submit event returns very fast and the browser dont have time to get the OPTIONS request. edit more later later: WTF, i resolve the problem make the POST request to sync: this.xhr.open("POST", url, false); The submit reponse very quickly and can't wait to the OPTION response of the browser, any idea to this?

  • Select options not showing in IE

    - by donkapone
    I have a dynamically generated select with some options and it shows the options fine in normal browsers, but its empty options in IE. Here's the generated HTML: <select name="0" id="custom_0" style="border-bottom: #c0cedb 1px solid; border-left: #c0cedb 1px solid; background-color: #ededed; width: 280px; font-size: 0.87em; border-top: #c0cedb 1px solid; border-right: #c0cedb 1px solid"> <option id="1000" value="0" name="00">1x2GB ECC DDRIII 2GB ECC DDRIII</option> <option id="1001" value="10" name="01">2x2GB ECC DDRIII 4GB ECC DDRIII (+10.00 €)</option> </select> I can't really show you the javascript, since there's so much of it and I would be able to make it simple just for a demo. Maybe you had some of you would've had a similar experience and could figure this one out. Thanks I've added some javascript: $('#custom_order').append('<tr id="custom_'+category+'_row"><td'+padding+'>'+header+'<select id="custom_'+category+'" name="'+category+'" style="background-color:#EDEDED;border:1px solid #C0CEDB;width:280px;font-size:0.87em"></select>'+plusspan+'</td></tr>'); for (var i=0;i<components[category]['value'].length;i++){ $('#custom_'+category).append('<option id="'+components[category]['value'][i]['id']+'" value="'+components[category]['value'][i]['price']+'"></option>'); removals(category,i); dependencies(category,i); selectInput(category); } getDiff(category); getDiff() function adds the values to the options with html() function. The weird thing is, if I alert the html of the option just after the getDiff() function, it shows the value filled out. And it I put the getDiff() function in the for loop where the options are generated, it fills the values and shows them in IE, just not the last one. I'm calling getDiff() outside the loop for optimization, and since I can add the values later after all the options are generated. Well at least I thought I could, since it works on Firefox and Chrome.
