Core allows real-time transcoding between an HEVC / H.265 input stream to an H.264 / AVC output stream.
This allows an HEVC stream from an encoder to be converted and delivered to hardware decoders or clients which only accept H.264 streams, or the use of streaming protocols which only support H.264.
The RTMP streaming protocol is not compatible with HEVC, but the MPEG-TS protocol and SRT protocols both support the HEVC codec in addition to the older H.264 codec.
NOTE: if transcoding is not activated, the incoming HEVC stream from the encoder will be left at HEVC by the Sputnik server and will not be converted to H.264. This means that both the outbound streams sent from a Core-controlled Sputnik must be capable of supporting the HEVC codec, and the destination must also be capable of receiving HEVC.
The transcoding feature can only be activated on an Advanced, Premium or Enterprise plan with a dedicated Sputnik server.
The Starter Plan with On Demand Sputniks is not supported.
The transcoding server is an additional $8/hour charge to operate, and in addition to any other fees on the Core plan.
