How can I fix MediaRecorder FPS?

Hello!

It seems that the fps of the video captured using MediaRecorder depends on the rendering fps at the time.
Is it possible to fix this to 24 fps for recording?

According to this document, ( if 8thwall’s MediaRecorder internally uses captureStream() ), captureStream() can accept a frame rate as an argument.
Is there a way to set this option?

Thank you!
