Live Stream: Playback Stall during Low Bandwidth Speeds(450kbps and below) after receiving HLSEvent.WARNING

Nobody has claimed this yet.

Playback doesnt continue once HLSEvent.WARNING is received. But the fragments continue to be downloaded.

This always happens when Network throttling is used on Chrome Browser and is set to Good 2G and below.

I have set the Network Throttling to **GPRS(500ms, 50kbps, 20kbps)** to demonstrate it quicker.

Reproduce the stall in Chrome using Good 2G or the GPRS throttling settings described, then start with the HLSEvent.WARNING path and the fragment-loading logs. Compare playback state with continued fragment downloads and the ERR_CONTENT_LENGTH_MISMATCH parsing error. Done means live playback continues or recovers after the warning while fragments keep downloading.
