Are you willing to contribute it

None

Describe the feature and the current behaviour/state

Mediapipe does not support setting the maximum number of threads to use.

Will this change the current API? How?

Add a function or env var to set the macimum number of threads.

Who will benefit with this feature?

People with many cores on their system since the default number of threads seem related to it.

Please specify the use cases for this feature

Running multiple models in parallel (in different processes) creates mtoo many threads which is detrimental to efficiency.

Any Other info

Hi @nlgranger,

Thanks for reaching out,

I understand that in systems with many cores, especially when running multiple MediaPipe instances in parallel processes, this default behavior can lead to a very large number of threads, potentially causing performance issues due to contention, scheduling overhead, or resource limits. I'll discuss this with the team and I'll get back to you 😊.
