Video chunking for robust, progressive uploading

摘要

Systems and methods are provided herein relating to video chunking for robust, progressive upload. Video can be parsed to determined byte offsets associated with prospective chunk boundaries. Chunks can be generated based on the prospective chunk boundaries and a preferred chunk size. Sample tables can be generated for each chunk. The chunks can be fully self contained, in that they can be received and transcoded independently of other chunks. Thus, if one chunk fails, only that chunk needs to be retransmitted versus the entire video.

1. A device comprising:
a memory that has stored thereon computer executable components; and a processor that executes the following computer executable components stored in the memory:
a receiving component that receives a video sample;a parsing component that parses the video sample to determine chunk boundaries and respective byte offsets associated with the chunk boundaries;a chunking component that generates a set of chunks based on the chunk boundaries, the respective byte offsets, and a preferred chunk size wherein chunks in the set of chunks are self contained;a sample table component that generates a set of sample tables for respective chunks among the set of chunks based on sample tables associated with the video sample;a packing component that packs respective chunks among the set of chunks and associated sample tables into subcontainers; anda transmission component that transmits respective subcontainers to a media sharing service separately.
