An encoder includes a processor, a buffer, and a memory. The memory includes code as instructions that cause the processor to perform a number of steps. The steps include partitioning a geometric construct within an axis of the geometric construct based on a point differential between two partitions, the geometric construct including geometric data, determining a number of points in the partition, storing a value indicating the number of points in the buffer, and entropy encoding the value stored in the buffer.

Systems and methods are provided herein relating to adaptive video streaming. Time-to-offset mapping associated with a set of video blocks can be broken up into chunks. A client can download a first set of seek index chunks and use the first set of seek index chunks to select a stream. Seek index chunks within remaining sets of seek index chunks can be ranked for relevance based on client capabilities. A subset of remaining sets of seeks index chunks can be downloaded based on the rankings and client capabilities during streaming. Chunked time-to-offset mapping can facilitate faster startup when playing streamed video.
