Large files & remuxes buffer while streaming in the same network

[TheDreadPirate]

So I realized that web browsers are not ideal for playing media on desktop....

...

I unchecked every transcoding option and disabled hardware acceleration, and I wasn't able to play the same file 64Mb/s bitrate file on the web browser (the one that I shared mediainfo of in previous post), and my CPU was running at 100% while I was trying to play it. The same file worked flawlessly in the Jellyfin Media Player with the same settings. I'm not sure why it did that. 

Your videos were HEVC.  The only browser I know of that actually plays HEVC is Microsoft Edge (requires extra software to make this happen).  Turning off all the hardware acceleration options will only result in CPU transcoding.  Which is very very demanding even at 1080P.

Re-enable NVENC hardware acceleration. Your GPU supports every codec EXCEPT AV1. Also enable tone mapping.

My only concern is that will I be able to see the actual HDR10 without any tone mapping or transcoding enabled or does Jellyfin turns media to SDR when H/A and tone mapping is disabled? My assumption is that the files won't either play or if they do then the colors will be washed out. Also wanted to know if H/A impacts the quality of the videos.

Read my previous post about using Jellyfin MPV Shim as the player on your desktop.

I read the JF documentation regarding Hardware Acceleration and it has suggested to avoid H.264 / AVC 10-bit videos. I also assume that Dolby Vision videos would not play if Hardware Acceleration is disabled since my monitor doesn't support DoVi, but I take it that HDR10 would be playable since my monitor does support it, right?

AVC 10-bit has nothing to do with HDR10 or Dolby Vision.  Ignore that part.  Hardware acceleration only comes into play if the client can't directly play the video.

Regarding your monitor's capabilities, my understanding is that it shouldn't matter since the player you use with Jellyfin would decode the HDR signal.  I might be wrong.  I'm still a bit of an HDR noob.  But, again, see my prior post about Jellyfin Media Player's limitations and suggestion you use MPV Shim.
