I am setting the srcObj property of an audio element with the MediaStream of the user at the other end of the line (using PeerJS). I am also showing the time since the start of the call by displaying the currentTime property of the audio element every second. This works fine on windows chrome and firefox, but on webkit browsers (macOS AND iOS), the currentTime property is way too high. Like it is equal to several hours when the call has just started. Example: https://jsfiddle.net/vladmashk/j3ysLf29/1/ <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"/> </head> <body> <audio id="audioElement" autoplay></audio> <div>Time passed: <span id="timePassed"></span></div> <script type="module"> const audioElement = document.getElementById("audioElement"); const stream = await navigator.mediaDevices.getUserMedia({audio: true}); audioElement.srcObject = stream; setInterval(() => { document.getElementById("timePassed").innerText = audioElement.currentTime; }, 1000) </script> </body> </html> 2085356 1 webkit-bug-importer 2025-01-07 01:44:03 -0800 <rdar://problem/142465970> 2085357 2 youennf 2025-01-07 01:48:37 -0800 Pull request: https://github.com/WebKit/WebKit/pull/38633 2085383 3 ews-feeder 2025-01-07 04:59:13 -0800 Committed 288519@main (8194ca4f8b6f): <https://commits.webkit.org/288519@main> Reviewed commits have been landed.
