Abstract: The disclosed embodiments relate to a file-communication system that enables a user to stream high-quality media (for example, from their Dropbox™) During operation, the system streams the media at an initial quality level to a client via a channel. For example, the quality level may be one of a set of quality levels associated with different transcoding operations. Then, the system determines or obtains an indicator of performance for the channel. Based on the indicator, the system spawns an additional transcoding operation at a different quality level than is available in the set of quality levels. The resulting media at the different quality level is then streamed from the system to the client via the channel.
