jmAt the beginning of the development of this feature, we entertained the idea to simply pre-transcode all the videos in Dropbox to all possible target devices. Soon enough we realized that this simple approach would be too expensive at our scale, so we decided to build a system that allows us to trigger a transcoding process only upon user request and cache the results for subsequent fetches. This on-demand approach: adapts to heterogeneous devices and network conditions, is relatively cheap (everything is relative at our scale), guarantees low latency startup time.
