Intel Releases Open Source Encoder for Next-Gen AV1 Codec
Intel published its own open source CPU-based encoder for the next-generation and royalty-free AV1 codec (a codec is a program for encoding / decoding a digital data stream or signal). Intel is one of the main founding members of the Alliance for Open Media (AOM), the non-profit group behind the development of the AV1 codec.
Intel's new encoder, called Scalable Video Technology AOMedia Video 1 (SVT-AV1), aims to fill the role of a good CPU-based encoding software tool until dedicated AV1 encoders are ready for prime time. The encoder supports the Linux, macOS and Windows operating systems.
A CPU-based encoder requires a beefy system, so it's no surprise the real-time encoding specifications for SVT-AV1 are no joke. SVT-AV1 requires Skylake-generation or newer Xeon processors with at least 112 threads and at least 48GB of RAM for 10-bit 4K video encoding. Outside of video streaming companies, these type of systems are out of reach for most. Consumers that want to encode AV1 videos may want to wait for dedicated AV1 encoding hardware to appear, which make take another year or so.
Here's a recent 42-minute talk (no transcript) about AOMedia Video 1 (AV1). Hardware support for AV1 should begin appearing around 2020.

I think you are missing the point. If you have a 'raw' bitstream, it is not MPEG-2 or MPEG-4 AVC encoded. If you have a bitstream that is already compressed, you are not looking for an encoder, but a transcoder.
If Apple don't want to support open standards, shrug. AFAIK they support WebRTC by supporting the Opus audio codec and H.264 for video [bloggeek.me], and it looks like VP8 has been added to Webkit/Safari. [webkit.org]
Have a nice day.

Precisely. Someone doing a lot of HD to SD transcoding would need to use older encoders (x264 or libvpx) until AV1 encoding hardware or more time-efficient AV1 encoding software becomes widespread.

Apple is a founding member [aomedia.org] of the Alliance for Open Media. So it's a sure bet that they will support AV1 when they are ready to do so.
