Overview: Understanding playback behavior

Playback behavior links visible symptoms to observations of the stages involved in a media session.

A late start, a stall and a dropped frame describe different results. Diagnostic information can then show which source, conversion or delivery path was active. This group pairs those symptom definitions with ways to capture evidence, so the investigation follows the actual session rather than one assumed cause.

• Playback symptoms
  Playback symptoms describe distinct failures or limits in starting, continuing and presenting media.

• Playback diagnostics
  Playback diagnostics capture the active media path and enough context to reproduce or explain its result.
