It's not possible to always provide accurate values for duration -
we've already discussed that and you suggested estimating. I don't see
that as an accurate value. Can you link to the post where implementors
said they would always provide accurate values? The only accurate
value I can provide with Ogg is the exact duration if the http server
supports byte range requests, or some other out of band duration
metadata (X-Content-Duration, etc). Without byte range requests,
accurate duration is not possible.
