A friend of mine has this VR app based on krpano https://ohwvr.nl/Hoornbrug-1200/tour.html and he wants to enter VR mode automatically instead of having to click on the mask.
I tried the following:
<script>
function krpanoReady(krpano) {
console.log('krpano', krpano);
krpano.call("webvr.enterVR();");
}
embedpano({
xml:"tour.xml",
target:"pano",
html5:"only",
mobilescale:1.0,
passQueryParameters:"startscene,startlookat",
onready: krpanoReady,
});
</script>
But it seems to only work with onclick, is this a limitation of the WebVR/XR API?

Well the point is the following:
import {
Camera,
CameraResultType,
CameraSource,
Photo,
} from "#capacitor/camera";
export function usePhotoGallery() {
// import { usePhotoGallery } from "../hooks/usePhotoGallery"; per usarlo in esterna
const scatta = async () => {
const cameraPhoto = await Camera.getPhoto({
resultType: CameraResultType.Uri,
source: CameraSource.Camera,
quality: 100,
});
};
return {
scatta,
};
}
With this pretty basic code just calls the default camera and makes it take a shot.
It's working fine no problem. The issue comes in, by my case, by the fact that i have a custom ROM with no pre-installed camera. So no default camera. I know pretty much no one would have my issue. But I'd like to cover those 0.1% of user that will have this problem.
So, finally, how can I can use a 3rd party camera app? Or just create one if it's better.
For example I can take photos from Whatsapp, Instagram, Snapchat ecc. I guess cuz they have their own camera. So the point basically is:
How can I make the user select the app he prefers for thake the shot (like the pop-up that ask "open with *choiches*.."
If i can't do the previous option, then how can I do my own camera?
Sorry for my probably disgusting english
I have been building an app in Adobe AIR using HTML/JavaScript.
The windows are all Chromeless and use CSS to style them to look like an application.
How can I detect if the window is focused by the user so I can alter the colours of the windows in the same way that native windows have more subtle shadows etc.
An example might be:
var active = false;
$(document).ready(function() {
active = nativeWindow.active;
if(active) {
$('body').addClass('active');
} else {
$('body').removeClass('active');
}
});
But how do I properly handle the change of active event?
You can do this with: air.NativeWindow.active. See: http://help.adobe.com/en_US/air/reference/html/flash/display/NativeWindow.html#active
UPDATE:
window.nativeWindow.addEventListener(air.Event.ACTIVATE, function() {
$('body').addClass('active');
});
window.nativeWindow.addEventListener(air.Event.DEACTIVATE, function() {
$('body').removeClass('active');
});
I would like to show the big play button at the end of the video, so user can replay it easily.
It seems that this big play button is shown by default (every posts I read are for hidding it instead of showing it...), but it is not the case for me...
I have tried to edit the following function (in video.dev.js file) but nothing has changed :
vjs.Player.prototype.onEnded = function(){
if (this.options_['loop']) {
this.currentTime(0);
this.play();
}
else { // I am not using loop mode
this.bigPlayButton.show();
this.pause();
}
};
Thanks for your responses.
There are a few ways you can do this. You can show the button when the video ends with the API:
videojs("myPlayer").ready(function(){
var myPlayer = this;
myPlayer.on("ended", function(){
myPlayer.bigPlayButton.show();
});
});
Or if you do want to modify video.dev.js you just need to uncomment the line that does the same thing:
vjs.BigPlayButton = vjs.Button.extend({
/** #constructor */
init: function(player, options){
vjs.Button.call(this, player, options);
if (!player.controls()) {
this.hide();
}
player.on('play', vjs.bind(this, this.hide));
// player.on('ended', vjs.bind(this, this.show)); // uncomment this
}
});
Or with CSS you could force the button to be showed whenever the video is not playing (ended or paused):
.video-js.vjs-default-skin.vjs-paused .vjs-big-play-button {display:block !important;}
The posts you've seen about hiding it probably refer to version 3 of video.js, as with that the play button was shown at the end.
Place this code after the videojs code. Works great. It not only shows the poster and the big play button, but also allows you to re-play the video again and again:
<script type="text/javascript">
var vid = videojs("YOUR-VIDEO-ID");
vid.on("ended", function()
{
vid.posterImage.show(); //shows your poster image//
vid.currentTime(0);
vid.controlBar.hide(); //hides your controls//
vid.bigPlayButton.show(); //shows your play button//
vid.cancelFullScreen(); //cancels your fullscreen//
document.mozCancelFullScreen(); //cancels your fullscreen in firefox//
});
vid.on("play", function() //function to play the video again//
{
vid.posterImage.hide(); //hides your poster//
vid.controlBar.show(); //shows your controls//
vid.bigPlayButton.hide(); //hides your play button//
});
</script>
The only thing I can't get to work is the exit fullscreen with firefox... But I don't know what else to do.
I don't know why but I cant get the answers mentioned here to work, maybe it's because I am on a newer version of the player, so doing things like vid.posterImage.show() is not doing anything for me.
On version 5.19.2 (current release), I was able to reset the player to it's default state (before the play button is pressed by the first time) by setting hasStarted to false on the event listener "ended".
example:
var player = videojs('player');
player.on("ended",function(){
player.hasStarted(false);
});
That brings back the big button, the poster, and hides the controls.
I created this plugin to "reset" the player and show the big play button and the video's poster

I read the entire API and dozens of related help topics but I dont manage to get with the code to help me do what I want.
This is what I need:
The video is muted by default.
When user click on fullscreen button the video is played with full volume.
How do I code this?
I understand I can mute my video adding myPlayer.volume(0) like this:
<script>
var myPlayer = _V_("video_1");
myPlayer.volume(0);
</script>
But how do I detect whether the video is in fullscreen or not?
I found the fullscreenchange event on the API but dont manage to implement it successfully. Any help will do my day. Thank you!
Listen for the fullscreenchange event and check the isFullScreen property of the player.
var myPlayer = _V_("video_1");
myPlayer.volume(0);
var onFullScreen = function(){
if (this.isFullScreen) {
this.volume(1);
} else {
this.volume(0);
}
};
myPlayer.addEvent("fullscreenchange", onFullScreen);

I'm using jCaptcha (http://jcaptcha.sourceforge.net/) on our website. The problem is sometimes it's very difficult to read the image. So, we are planning to provide a button named 'REFRESH' next to the jcaptcha image and upon clicking REFRESH button, it has to refresh only the jcaptcha image not the entire page/portlet. How can we do that?
This is how I solved it using JQuery, it will replace the image. The alert() is just there to show off the new filename and can of course be removed. The code is using the jquery plugin in grails but shows what to do in jquery to refresh the image.
<div>
<jcaptcha:jpeg name="captchaImage"/>
Refresh captcha
<jq:jquery>
$("#refreshCaptcha").click(function() {
$("#captchaImage").fadeOut(500, function() {
var captchaURL = $("#captchaImage").attr("src");
captchaURL = captchaURL.replace(captchaURL.substring(captchaURL.indexOf("=")+1, captchaURL.length), Math.floor(Math.random()*9999999999));
alert(captchaURL);
$("#captchaImage").attr("src", captchaURL);
});
$("#captchaImage").fadeIn(300);
});
</jq:jquery>
</div>
Make this changes in JSP :
<img src="jcaptcha" id="captcha_image"/> Refresh
Add the Javascript function like :
function reloadCaptcha(){
var d = new Date();
$("#captcha_image").attr("src", "jcaptcha?"+d.getTime());
}
You would have to load the image and the refresh button into . Than you should be able to refresh just the iframe. But the I don't know how you are performing your validation so.
Set an id for the img tag and let it call a javascript function:
<img src="jcaptcha.jpg" id="captchaImage"/>
javascript function:
<script type="text/javascript">
function refresh()
{
var captchaImage=document.getElementById("captchaImage");
captchaImage.src="jcaptcha.jpg";
}
</script>
this works fine because i implemented this one in my project just create one button on clicking that button it will come to below menctiond block of code like that you do
<script type="text/javascript">
function refresh()
{
var image=document.getElementById("kaptchaImage");
image.src="<%=request.getContextPath()%>/kaptcha.jpg?"+Math.floor(Math.random()*100)
}
</script>
