So can I assume HTML5 spec also allow playbackRate to be negative
value.
ie to support go backward at various speed....
Yes.
Would you expect the audio to be played backwards too?
I think that's extra credit and optional. As you say, even with audio
coded in independent frames you have to flip the samples, which is a
pain. For audio with forward dependencies, correct decoding means
decoding forwards and then flipping whole chunks of timeline (though AAC
doesn't suffer too badly if you don't do this, by the way).
Honestly, this seems useless enough that the spec should just say that
when playback is less than 0 sound should be turned off. I'd hate to see
engineers working on this just because "the spec says it should work
that way".
