![]() ![]() Mixing protocols will generate its own security errors. But I don't think that is what is causing your issue.Īlso be aware that both your site and the src you're linking to needs to use the same protocol. I should also mention that Edge's tracking prevention is also triggering on this so that isn't good either. The workaround would be to configure CORS to allow that domain to access your site but you're opening yourself up for potential attack so be wary. Hence why you're getting the failed to read error as the iframe does not have access to the parent window because it is not on the same domain. This helps sandbox the contents and prevent malicious actions but it is not foolproof. Most browsers have limited the ability to access anything on the parent page within an iframe. is your issue, temporarily remove the mark-up of the controls and any reference you had to them in the code behind, ie make it so you can successfully build. If a malicious user injects content into your site then they would have the same access to the client as your app would which could expose sensitive data. If you are having problems with a specific control, try to create one near the top of the page, if that doesnt work either, its a code generation problem. This is the gist of why CORS is so important. For example, nothing would prevent a malicious user (or script) between you and a web server from injecting an iframe that has a source pointing to a completely different domain. iframes are a great way to inject malicious code into a site and every modern browser is purposefully starting to block iframe usefulness. The most important part of the application is here: // src/RecordView.Don't use an iframe. The main app is simple, it only includes one component. The react-media-recorder is ready to use the component that will help us record the video stream from a laptop camera. One would be named as SetCookie.html and the other one would be GetCookie.html. This iframe will point to my server and I should be able to access a cookie set by the vendor in their main page. This will solve the issue of accessing camera/microphone within iframe using a different domain. I have an iframe set in one of their html pages. Our React application has a button ‘Click to fix permissions’, which will add a proper attribute to iframe. Solution preview Video Recording with preview After stopping, the recorded playback will be played. ![]() During recording, we will see a video preview. To showcase cross-origin camera access from iframe, our demo will show the recording status as well as 2 buttons for starting and stopping the recording. The test page test.html will be hosted on the Netlify server to check the cross-domain ability to access the camera within iframe. Click to fix permissions Media Recorder APIįor demonstration purposes, we’re going to create a simple React App in iframe that uses Media Recorder to record audio and video. reset MediaRecorder permissions by changing src urlĭ.setAttribute("src", iframeUrl + '?v=2') Į.target.appendChild(document.createTextNode(' ✔')) Ĭonst d = document.getElementById("iframe1") ĭ.setAttribute("allow", "autoplay camera microphone") The trick is to reload iframe (change src with query string addition), otherwise, permissions will not be updated. To fix the error, we can add the allow attribute inline, or we can do it dynamically using Javascript. Without adding the allow attribute to iframe, the MediaRecorder API will return: Error: permission_denied. ![]() To allow access to devices we can use the allow parameter that should be added to iframe. In a situation when iframe uses a different domain, access to the camera is blocked. It’s not a rare situation when we want to conduct a video chat in iframe. SOLUTION: use the iframe “allow” parameter ![]() CHALLENGE: request access to the camera and microphone within iframe ![]()
