如何在react js中旋转视频

如何解决如何在react js中旋转视频

我使用 navigator.mediaDevices.getUserMedia 和 MediaRecorder 在 react js 中将相机录制为视频。 如何将视频旋转 90 度？

navigator.mediaDevices.getUserMedia({video: {
      facingMode: 'user'        
    }})
      .then(function (stream1) {         
        video && (video.srcObject = stream1);
        stream = stream1;
        mediaRecorder = new MediaRecorder(stream);           
      
        mediaRecorder.ondataavailable = function(e: any) {
          chunks.push(e.data);
        };
      
        mediaRecorder.onstop = function(e: any) {           
          var blob = new Blob(chunks,{ type : 'video/mp4' });
          chunks = [];
          var videoURL = URL.createObjectURL(blob);
        };
      });
