MediaPipe Pose on two synchronized videos

[mcdonasd1212]

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

Yes

OS Platform and Distribution

Ubuntu 22.04.4 LTS

MediaPipe Tasks SDK version

0.10.11

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

Pose

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

Python

Describe the actual behavior

When implementing 10.11 the code example is very slow. However with the legacy code, the example performance is acceptable.

Describe the expected behaviour

MediaPipe 10.11 to have similar performance as legacy for the example.

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

Here is an example the example code with acceptable performance. How can I implement 10.11?

Hi @mcdonasd1212,

After reviewing the provided standalone code, it appears that you are currently using the outdated pose solution, which is no longer maintained, and we have ceased support for it. This functionality has been integrated into the new Pose Landmarker Task API, detailed here.

We encourage you to explore the features of our updated Pose Landmarker Task API and suggest replacing the legacy Pose with the new Pose Landmarker. The new solution offers improved performance and additional functionality compared to the legacy pose solution. You can find the guide for the new Pose Landmarker here, along with specific instructions for implementation in the Python platform provided here. Additionally, a corresponding example Colab notebook is available for reference here.

Please report any observed behavior, ensuring to check if similar issues persist in the upgraded task API. We value your feedback. Unfortunately, beyond this, there is limited action we can take to address the specific issue you are facing.

Thank you!!

[mcdonasd1212]

Sorry for the confusion, I am asking why the legacy pose solution works, the NEW POSE LANDMARKER DOES NOT.

Any advice?

Hi @mcdonasd1212,

Please verify with the latest version 0.10.13, which we recently released. If the issue persists, could you kindly provide the standalone code or steps you are following from our documentation, along with the version of Python being used, to reproduce the issue? This will help us identify and address any genuine bugs.

Thank you!!
