At least with software decode we would know that it has failed - an inconvenient property of many hardware decoders is their reluctance to report errors usefully or at all. Hence the warning on using the ALLOW_PROFILE_MISMATCH flag, which does allow the attempt to decode baseline profile streams with hardware: """ If the stream is actually not supported then the behaviour is undefined, and may include returning entirely incorrect output while indicating success. """ I think the behaviour we have now with this option to continue if the user really wants (and is aware of the possible consequences) is correct.
