We do not allow streams to have independent timelines (e.g. no adjustable playback rate or seeking within an arbitrary Stream), because that leads to a single Stream being consumed at multiple different offsets at the same time, which requires either unbounded buffering or multiple internal decoders and streams for a single Stream. It seems simpler and more predictable in performance to require authors to create multiple streams (if necessary) and change the playback rate in the original stream sources. | We do not allow streams to have independent timelines (e.g. no adjustable playback rate or seeking within an arbitrary Stream), because that leads to a single Stream being consumed at multiple different offsets at the same time, which requires either unbounded buffering or multiple internal decoders and streams for a single Stream.
