Successor of RTMP for VP9/OPUS streaming ?
Hey,
So I was wondering, let's say someone were to create a new streaming platform (such as twitch) with one big difference : the codecs would have to be VP8|9 and OPUS. And I'm not talking about the broadcaster sending H264/AAC and then the platform transcoding, I'm talking about VP9/OPUS through the whole pipeline. What would be the drop-in replacement for RTMP ? Would DASH be an option ? As far as I understand, one of the problems with DASH is that it introduces latency. And can it even be used for the broadcaster -> platform part ? I was also wondering about the media protocol inside WebRTC. Anyone knows what it is ? It's a protocol that can handle VP9/OPUS streaming from client to client, so this would be a very interesting path to follow. Thanks! |

1) Just about everyone is using HLS (twitch does as well)
2) list of problems with "new and exciting next-gen codecs blabla" - no guarantee of mobile decoders (not even every _desktop browser_ has them) - there goes 40% of your audience - vbv bitrate controls/limits are awful - makes people lag and stresses delivery routes - extremely slow encoding for broadcasters - atm even for x264 the prevailing preset is veryfast |

Does HLS support VP9 and OPUS ? Also, can it be used as a client to platform protocol ? |
