Techniques described herein are directed toward creating one or more 'dynamic profiles' for media (video) streaming in which an encoding bit rate (and optionally other profile settings) is optimized for particular content. More specifically, techniques involve performing one or more “probe” encodings of the particular content to determine an encoding bit rate (and optionally other profile settings) that results in an encoding having a quality value sufficiently near (within a threshold) a target quality value.

Optimization of encoding profiles for media streaming

Techniques are disclosed for the creation of multi-codec encoding profiles (or encoding ladders), which define quality and bitrate for each of the streams made available to clients for streaming a video. In particular, optimization techniques may take into account a quality rate function of each of the codecs when determining the encoding ladder. Additional considerations may include a network bandwidth distribution and/or a distribution of client types.

Optimal multi-codec ABR ladder design

Techniques described herein are directed toward creating one or more 'dynamic profiles' for media (video) streaming in which an encoding bit rate (and optionally other profile settings) is optimized for particular content. More specifically, techniques involve performing one or more 'probe' encodings of the particular content to determine an encoding bit rate (and optionally other profile settings) that results in an encoding having a quality value sufficiently near (within a threshold) a target quality value.

A method for dynamic file availability during remote transfer and transcoding involves the conversion of a non-streamable media file to a streamable format prior to transcoding, and the streaming of the transcoded file before ingest and transcode is complete. A first portion of a non-streamable media file is received at an ingest server for transcoding. Upon determining that the first portion does not include a header, the probable location of the header in the media file is determined and a header portion of the file is received at the ingest server. The first portion is combined with at least part of the header to produce a first streamable segment. Prior to receiving the last portion of the media file at the ingest server, the first streamable segment is transcoded at a first transcode server to produce a first transcoded streamable segment.
