Can't take out all the computation power of your multi-processor system when doing transcoding? A new technology being developed in MediaCoder will be the solution. I name it SVE (Segmental Video Encoding). It is like multi-segments downloading, but the difference is the segmentation is temporal instead of spatial. Multiple instances of the same encoder are used to encode the different part of one video concurrently. The result bitstreams are merged by muxer together with audio. My practice has proved that this is completely feasible, without almost no compromise. This will increase overall transcoding speed on all under-loaded systems (a system with many CPUs or processor cores) reglardless of the encoder's multi-threading capability, as well as GPU encoding (in most cases GPU is under-loaded when encoding a single stream). My test has shown a 20% speed boost of Intel MSDK GPU encoding on the same Intel i7-2600 system. Distributive encoding will also benefit from this technology. So stay tuned!
