// Prepare MediaRecorder recordedChunks = []; mediaRecorder = new MediaRecorder(mediaStream);

// Show preview previewVideo.srcObject = mediaStream;

// Stop recording if user clicks the browser's native "Stop sharing" button mediaStream.getVideoTracks()[0].onended = () => stopRecording(); ; catch (err) console.error("Error: " + err);

The days of relying on third-party software for screen recording are fading. With the Screen Capture API (often searched as api grabador de pantalla ), modern web browsers can capture screen content, individual windows, or browser tabs directly using JavaScript.

function stopRecording() if (mediaRecorder && mediaRecorder.state !== 'inactive') mediaRecorder.stop(); mediaStream.getTracks().forEach(track => track.stop()); previewVideo.srcObject = null; startBtn.disabled = false; stopBtn.disabled = true;

While it has limitations (especially with system audio), it eliminates the need for browser extensions or native plugins for most basic to intermediate screen capture needs. api grabador de pantalla

mediaRecorder.start(1000); // Capture data every second startBtn.disabled = true; stopBtn.disabled = false;

mediaRecorder.onstop = () => const blob = new Blob(recordedChunks, type: 'video/webm' ); const url = URL.createObjectURL(blob); recordedVideo.src = url; downloadLink.href = url; downloadLink.download = 'screen-recording.webm'; downloadLink.style.display = 'inline'; ;

mediaRecorder.ondataavailable = (event) => if (event.data.size > 0) recordedChunks.push(event.data); ; mediaRecorder
