Yeah, I know that lossless is huge, but was curious if there were any options since it will be a question that gets asked, and therefore I want to be prepared. My experiements suggest that even where there are codecs that have a lossless or near-lossless feature in the spec, they tend not to be implemented, especially in browsers. So I guess that’ll be a big “nope” for now… unless someone has further guidance.
The only adjustment I'd make is that "for now" implies that real-time lossless video transmission across the public internet might become available in the foreseeable future.
Uncompressed 1080p video at 4:2:0 color sampling minimally takes 1.5 Gbps. Lossless compression like FFV1 would knock that down to ~600 Mbps, depending on the source material (it does somewhere between 2:1 and 3:1 for most video sources). It is going to be quite a long time before this is realistically something that anyone outside a research environment can take advantage of.
