How to calculate the video frame rate #4699

Hello ,
We are using the getVideoPlaybackQuality() API of the video element to calculate FPS in our application. However, we’ve noticed that the data returned by this API is unreliable on some Smart TVs.

Is there an alternative method or approach within Dash.js to reliably calculate FPS?

Thank you for your help.

The only way that pops to my mind is using the information from the MPD. But this just gives you the encoded framerate not the rate at which the client is decoding the frames.
