📺 What

Update the videoFramesNotAdvancing implementation to handle additional invalid or inaccurate values being reported by the Video Quality API.

🛠 How

Deals with 3 observed cases:

• Increases the default thresholdInSeconds to 5. As many WebKit-based TV environment only appear to provide an update to this value every ~2-seconds
• Handle cases where some devices always report the maximum value of 32-bit signed integer as their totalVideoFrames value on the Video Quality API when playing a live stream. Caused by some implementations using totalVideoFrames = mediaTime * frameRate
• Finally, only trigger when frames are explicitly not changing, i.e previousFrames !== currentFrames. Some devices appear to reset totalVideoFrames to 0 if the decoder is reinitialised.
