    摘要： Technology for low-delay encoding of live video streams in multi-adapter systems can include a host processor and memory comprising instructions which, when executed, cause a computing system to encode, via a first graphics adapter, an I-frame of a live video signal and a first subset of P-frames of the live video signal, encode, via a second graphics adapter, a second subset of P-frames of the live video signal, and combine the encoded video frames from the first adapter and the encoded video frames from the second adapter into an output video bitstream. Frames of the live video signal are divided into the first and second subsets of P-frames on an alternating frame basis, and the I-frame copied from the first graphics adapter to the second graphics adapter prior to encoding the second subset of P-frames, such that encoding the first and second subsets of P-frames occurs essentially in parallel.

    摘要： A method for media content streaming includes: receiving a command to start playback of a first media content item, wherein a first portion of the first media content item has been transcoded to generate at least one passive adaptive streamlet, and the first portion of the first media content item starts at a playback position and ends at an optimal transition point; outputting, by a content streaming device, one of the at least one passive adaptive streamlet; while outputting the one of the at least one passive adaptive streamlet, requesting, receiving, and transcoding a second portion of the first media content item to generate an active adaptive streamlet of the first media content item, wherein the active adaptive streamlet starts at the optimal transition point of the first media content item; and immediately following outputting the one of the at least one passive adaptive streamlet, outputting the active adaptive streamlet of the first media content item.
