  1. Chrome only has fallback for no-preference when hardware encoder encounters an error. It will try software encoding.
  2. Spec doesn't currently have any language allowing fallback. We could add a note forbidding fallback.
  3. @dalecurtis to gather stats on current fallback mechanism.
  4. Way forward for current users is to specify prefer-hardware or prefer-software which won't trigger fallback in Chrome.
  5. @aboba to ask media WG (Mar 7th) for opinions on whether developers prefer automatic fallback or want explicit control even in no-preference case.
