AppleTV HLS player with metrics?

Hello, I am running some simple playback tests. I would like to playback content streamed via HLS manifest on my AppleTV device, ideally with playback metrics.

I should be able to use something like the VLC app: https://www.videolan.org/vlc/download-appletv.html (open to suggestions)

But as for metrics, im not 100%. Does anyone have experience on this topic?

As for the specific metrics, Im just looking for something that I can use to objectively measure different tests. I was thinking anything related to buffer rates, error rates, and percentage of time playing back specific streams.
