I want to implement image uploading. It works for web (Chrome/Safari), but not for mobile ios (built with Capacitor). It shows image selection, but when I select it nothing happens.
Here is my input:
<q-file
v-model="avatarFile"
accept=".jpg, .png"
#input="uploadImage"
/>
async uploadImage() {
if (this.avatarFile) {
let extension = "jpg";
if (this.avatarFile.type === "image/png") {
extension = "png";
}
try {
this.loading = 1;
const {
data: {
uploadUrl: { uploadUrl },
},
} = await this.$apollo.query({
query: GET_UPLOAD_URL,
variables: {
extension,
},
});
await axios.put(uploadUrl, this.avatarFile);
await setTimeout(() => {
this.$emit("on-image-upload");
this.loading = 0;
}, 3000);
} catch (e) {
this.alertError(e);
this.loading = 0;
}
}
}
What am I doing wrong? Thanx in advance!
Found the solution. My accept rule had the wrong format. This works:
accept="image/*"

When using the geolcoation api in a react-native-webview, I am asked twice whether the app is allowed to use my current location. How is it possible to forward the already (not) granted permission to the webview?
I am currently using react-native 0.68 and react-native-webview 11.22.
First prompt:
Second prompt:
I should only be asked once for permission to use my current geolocation.
In case somebody faces the same problem, I solved this issue with the following workaround. I injected a custome javacscript into the webview to override the used geolocation api in the webview. My custome script does all the communication with the app. The app returns the geolocation and so the webview doesn't need to aks for permission.
Custome Script

navigator.geolocation.getCurrentPosition = (success, error, options) => {
window.ReactNativeWebView.postMessage(JSON.stringify({ event: 'getCurrentPosition', options: options }));

eventData = JSON.parse(e.data);

I'm trying to develop an app where users can can video call to each other and share their screens using WebRTC technology. I have succeed with either video call or screen sharing app and now I'm trying to make it to be able to switch between getUserMedia and getDisplayMedia on button click during a call inside the same RTCPeerConnection but it doesn't work.
This is how I thought it could work:
function onLogin(success) {
var configuration = { offerToReceiveAudio: true, offerToReceiveVideo: true, "iceServers" : [ { "url" : "stun:stun.1.google.com:19302" } ] };
myConnection = window.RTCPeerConnection ? new RTCPeerConnection(configuration, { optional: [] }) : new RTCPeerConnection(configuration, { optional: [] });
myConnection.onicecandidate = function (event) {
console.log("onicecandidate");
if (event.candidate) send({ type: "candidate", candidate: event.candidate });
};
myConnection.ontrack=function(e){
try{remoteVideo.src = window.webkitURL?window.webkitURL.createObjectURL(e.streams[0]):window.URL.createObjectURL(e.streams[0])}
catch(err){remoteVideo.srcObject=e.streams[0]}
}
myConnection.ondatachannel=openDataChannel
openDataChannel();
startAVStream();
//startSStream()
};
function startAVStream(enable){
if(sStream)sStream.getTracks().forEach( function (track) {
try{myConnection.removeTrack( track, sStream );}
catch(e){}
} );
navigator.mediaDevices.getUserMedia({ video: true, audio: true }).then(s => {
if(!avStream){
avStream = s;
avStream.getTracks().forEach( function (track) {
myConnection.addTrack( track, avStream );
} );
}
}, function (error) { console.log(error); });
}
function startSStream(enable){
if(avStream)avStream.getTracks().forEach( function (track) {
try{myConnection.removeTrack( track, avStream );}
catch(e){}
} );
navigator.mediaDevices.getDisplayMedia({ video: true }).then(s => {
if(!sStream){
sStream = s;
sStream.getTracks().forEach( function (track) {
myConnection.addTrack( track, sStream );
} );
}
}, function (error) { console.log(error); });
}
Can anyone tell me how I can switch between tracks inside the same RTCPeerConnection or should I create 2 separate RTCPeerConnection - one for video/audio streaming and another for screen sharing?
Any help appreciated! Thanks!
You could use RTCRtpSender.replaceTrack to splice the screen capture track. This doesn't require renegotiation, and therefore has very low latency.
let newstream = navigator.mediaDevices.getDisplayMedia({});
let newtrack = newstream.getTracks()[1];
if(newtrack.kind !== 'video')
throw new Error('Eek!?');
pc.getSenders().forEach(async s => {
if(s.track && s.track.kind === 'video')
await s.replaceTrack(newtrack);
});
The test for s.track not being null deals with the case where you previously called replaceTrack(..., null).
shareScreen = () =>{
const success = (stream) => {
window.localStream = stream
// this.localVideoref.current.srcObject = stream
// localStream.replaceStream(stream);
this.setState({
localStream: stream
})
Object.values(this.state.peerConnections).forEach(pc => {
pc.getSenders().forEach(async s => {
console.log("s.track ",s.track);
if(s.track && s.track.kind === 'video'){
stream.getTracks().forEach(track => {
// pc.addTrack(track, this.state.localStream)
s.replaceTrack(track);
});
}
});
});
}
const failure = (e) => {
console.log('getUserMedia Error: ', e)
}
navigator.mediaDevices.getDisplayMedia({ cursor: true }).then(success).catch(failure)}
I created a opt-in app for potential interims for our company, i worked with Gatsby and for now am quite satisfied with the result. I made it an Progressive Web App as that is fairly easy with the gatsby plugin.
The PWA works great on Android and shows the background video as expected, but on iOS the video doesn't show.
I updated all the packages and dependencies to the last versions but that doesn't change a thing. I tried googling the issue but got a lot of search results off people trying to let a PWA play video in the background when the app is closed (not my case).

I expect the iOS PWA (safari) to show the video as it does on Android but instead it gives a grey screen.
I hope some one can help me out or point me in the right direction.
How big is your video ?
Last time I checked, iOS has a limit of 50MB for the cache of a PWA, so if your video is bigger than 50MB, that may be the reason it works only on Android (which doesn't have such restrictions).
I found this blog post that helped me fix this problem
To add Range request handling to gatsby-plugin-offline, I added a script called range-request-handler.js with the following:
// range-request-handler.js
// Define workbox globally
importScripts('https://storage.googleapis.com/workbox-cdn/releases/5.0.0/workbox-sw.js');
// Bring in workbox libs
const { registerRoute } = require('workbox-routing');
const { CacheFirst } = require('workbox-strategies');
const { RangeRequestsPlugin } = require('workbox-range-requests'); // The fix
// Add Range Request support to fetching videos from cache
registerRoute(
/(\.webm$|\.mp4$)/,
new CacheFirst({
plugins: [
new RangeRequestsPlugin(),
],
})
);
Then in my gatsby-config.js I configured the plugin to append the above script:
// gatsby-config.js
module.exports = {
// ...
plugins: [
// ...plugins
{
resolve: 'gatsby-plugin-offline',
options: {
appendScript: require.resolve('./range-request-handler.js'),
},
},
// ...plugins
],
// ...
};
Videos now work in the Safari browser for me. If there is a better way to implement this, I am all ears. For now it works as intended
I use Ionic Framework.
Camera works perfectly in Ionic View. But it doesn't work after compilitaion on iOS.
Please, help to find out what is the problem.
Camera code in services.js:
app.factory('FileService', function() {
var images;
var IMAGE_STORAGE_KEY = 'dav-images';
function getImages() {
var img = window.localStorage.getItem(IMAGE_STORAGE_KEY);
if (img) {
images = JSON.parse(img);
} else {
images = [];
}
return images;
};
function addImage(img) {
images.push(img);
window.localStorage.setItem(IMAGE_STORAGE_KEY, JSON.stringify(images));
};
return {
storeImage: addImage,
images: getImages
}
});
app.factory('ImageService', function($cordovaCamera, FileService, $q, $cordovaFile) {
function optionsForType(type) {
var source;
switch (type) {
case 0:
source = Camera.PictureSourceType.CAMERA;
break;
case 1:
source = Camera.PictureSourceType.PHOTOLIBRARY;
break;
}
return {
quality: 90,
destinationType: Camera.DestinationType.DATA_URL,
sourceType: source,
allowEdit: false,
encodingType: Camera.EncodingType.JPEG,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: false,
correctOrientation:true
};
}
function saveMedia(type) {
return $q(function(resolve, reject) {
var options = optionsForType(type);
$cordovaCamera.getPicture(options).then(function(imageBase64) {
FileService.storeImage(imageBase64);
});
})
}
return {
handleMediaDialog: saveMedia
}
});
Camera code in controllers.js:
app.controller('CameraController', function($scope, $cordovaDevice, $cordovaFile, $ionicPlatform, $cordovaEmailComposer, $ionicActionSheet, ImageService, FileService) {
$ionicPlatform.ready(function() {
$scope.images = FileService.images();
$scope.$apply();
});
$scope.addMedia = function() {
$scope.hideSheet = $ionicActionSheet.show({
buttons: [
{ text: 'Take photo' },
{ text: 'Photo from library' }
],
titleText: 'Add images',
cancelText: 'Cancel',
buttonClicked: function(index) {
$scope.addImage(index);
}
});
}
$scope.addImage = function(type) {
$scope.hideSheet();
ImageService.handleMediaDialog(type).then(function() {
$scope.$apply();
});
}
$scope.sendEmail = function() {
if ($scope.images != null && $scope.images.length > 0) {
var mailImages = [];
var savedImages = $scope.images;
for (var i = 0; i < savedImages.length; i++) {
mailImages.push('base64:attachment'+i+'.jpg//' + savedImages[i]);
}
$scope.openMailComposer(mailImages);
}
}
$scope.openMailComposer = function(attachments) {
var bodyText = '<html><h2>My Images</h2></html>';
var email = {
to: '',
attachments: attachments,
subject: 'Devdactic Images',
body: bodyText,
isHtml: true
};
$cordovaEmailComposer.open(email, function(){
console.log('email view dismissed');
}, this);
}
});
To resolve this problem you need to compile an app with XCode.
After XCode compilation camera works correctly.
Probably, the problem with camera was caused by Ionic compilation.
In my import photos script, I try to update a progressbar (Jquery UI) following a while loop with Ajax requests.
The JQueryUI progressbar, which is supposed to be displayed before the launch of ajax requests do it after. So I have the user feedback at the end of the execution of my while loop ... (The console shows me that these applications are running well, in the right order)
I thought about using live () or bind (), but I do not know how to test it ...
Here is my jquery code:
$(function() {
var percent_progressbar=0;
$('#myform').submit(function() {
$('#myform').hide();
$("#text_result").html("Import in progress : <span class='progression'>0/0</span>").show(10, function() {
$("#myprogressbar").progressbar({value:percent_progressbar});
$("#myprogressbar").show(10, function() {
if (jQuery.trim($("#id_src").val()).length!=0) {
// Total number of photos to import
$.ajax({
type : 'POST',
async : false,
url : '/nbphotos.php',
data : 'chem=mydir',
success : function(nbphotos){
if (nbphotos>0){
$(".progression").html("0"+" / "+nbphotos);
var finish=false;
var nb_photos_imported=0;
var ajax_done = false;
var resultat_ajax="";
// Variables envoyées en Ajax
var datas = desvariables;
while (nb_photos_imported < nbphotos) {
ajax_done = false;
$.ajax({
type : 'GET',
async : false,
url : '/traitement.php',
data : datas,
success : function(resultat){
resultat_ajax=resultat;
ajax_done=true;
nb_photos_imported++;
}
});
if (ajax_done==true){
if (resultat_ajax=="ok") {
percent_progressbar = Math.floor(nb_photos_imported*100/nbphotos);
$("#myprogressbar").progressbar("option", "value", percent_progressbar);
console.info("Succès ajax (resultat : OK) : "+percent_progressbar);
$(".progression").html(nb_photos_imported+" / "+nbphotos);
} else {
finish=true;
$("#text_result").html(ajax_done);
return false;
}
} else {
// ajax error => exit the while
console.info("Ajax execution error "+nb_photos_imported);
return false;
}
} // While
if (finish==true) {
$("#myprogressbar").hide('slow');
$('#text_result').html("Import of "+nb_photos_imported+" photos done.");
}
} else{

$("#myprogressbar").hide(10);
$('#myform').show("slow");
}
}
});
}
});
}); // callback #text_result.show()
return false;
});
});
Here is my new code. The console log show the progression of the percentage, the photos are imported, but I still have the display at the end. If I put a breakpoint with me debugging tool somewhere in the loop, the display is refreshing and everything is OK...
