Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

No

OS Platform and Distribution

iOS 16.4 and iOS 16.6

MediaPipe Tasks SDK version

0.10.15

Task name (e.g. Image classification, Gesture recognition etc.)

Pose Landmarker

Programming Language and version (e.g. C++, Python, Java)

JavaScript

Describe the actual behavior

tasks-vision -> detectForVideo function doesn't work for iOS 16.4 and 16.6 even with CPU delegate

Describe the expected behaviour

Should work because Pose (Legacy solution) works on iOS 16.4 and 16.6

Standalone code/steps you may have used to try to get what you need

// Mediapipe warmup

this.poseLandmarker = await PoseLandmarker.createFromOptions(vision, {
          baseOptions: {
            modelAssetPath: modelURL, // tried with full and lite models 
            delegate: "CPU"

          },
          minPoseDetectionConfidence: 0.6,
          minPosePresenceConfidence: 0.6,
          minTrackingConfidence: 0.6,
          runningMode: "VIDEO",
          numPoses: 1,
        });
        const canvas = document.createElement('canvas');
        canvas.width = 1;
        canvas.height = 1;

        const ctx = canvas.getContext('2d');
        if (ctx) {
          // Clear the canvas before drawing
          ctx.clearRect(0, 0, canvas.width, canvas.height);

          // Draw a single pixel
          ctx.fillRect(0, 0, 1, 1);

          this.poseLandmarker.detectForVideo(canvas, performance.now(),  (result) => {
            console.log("[event] PoseLandmarker initialized successfully");
            this.isInitialized = true;
            // Clear the canvas after we're done
            ctx.clearRect(0, 0, canvas.width, canvas.height);

            return this.poseLandmarker;
          });
        }

Hello Everyone. Wanted to update: the issue is isolated only to iOS 16.4 and iOS 16.6 versions. I tried iOS 16.1 and iOS 15, both work. Legacy Pose Model works on all iOS versions I tested though, we recently migrated to a newer model and are experiencing these issues. I read apple has made some bugs with webql in those updates where webQL 2.0 doesn't work, but what's interesting is that legacy model works.
