📺 What
Adds MSE target latency and current latency reporting to the debug menu. Useful when debugging low-latency content, particularly on TV hardware where some decoder behaviours do not match what might be expected
🛠 How
Uses existing
DebugTool.dynamicMetric()method to add these metrics each time atimeupdateevent is called.✅ Testing
Added underlying dash.js functions to the
mockDashInstance. No additional unit tests were added.Test Guidelines
👀 See
New fields are seen below when the MSE strategy is chosen. The values
NaNand 0 are seen when VOD content is played.The same changes are shown again, but using live low-latency content. Extra fields, along with the existing playback rate field, can be used to determine whether low-latency content is performing as expected.
