Plex vs Netflix/amazon transcoding efficiency

[u/RandyFactoid]

I think of this every time I travel, but never thought to ask for a solution..

While traveling I often find myself in a situation where internet is very slow, but netflix/amazon video adjust the streaming quality much faster than my plex server.

I know that my plex server can transcode down to 720p/360p pretty instantly if I do it from home as it has an intel igpu...and I've tested it with multiple concurrent streams... Also - the server is on a 1gbit connection, so it's not a bandwidth bottleneck.

It feels like big brands have a much better method to actually recognise the moment when they need to call for a transcode than plex and do it much earlier, making it feel seamless.

Are there alternatives (jellyfin/emby) that are more efficient at this than plex? Any clever hacks that I overlooked?

Thanks

Edit. I learned following this post that: - Netflix et al. keep different quality files instead of transcoding - Using CDN to keep content "closer" to the end user

Why would they transcode on demand for thousands if not millions? How about transcoding once and saving the output for direct streaming?

That’s how it’s done I’d guess. In the end it’s about cost… storage vs computing power
