Android TV max streaming bit rate

[Caption7133]

Hello there,

I am currently migrating from Plex to Jellyfin and tried to query the forum to find a answer for my question which I didn't.

Just installed Jellyfin on my Android TV and saw that there is no option to set an unlimited bandwith (200 Mbit is maximum).
On my server tab I see that it's currently being direct streamed.

My setup would be:
Docker deployment within VM (16 cores & 8 GB RAM), Nvidia A4000.
I am using a reverse proxy for TLS termination.
Networkwise my Docker and reverse proxy are using a 10 Gigabit connection (which is 40 Gigabit connection from hypervisor to switch).
The connection continues over a router to an edge switch - again all 10 Gigabit. From the edge switch to Nvidia shield I am using 1 Gbit.

On Plex I was able to stream uncompressed 4K videos over this setup. It saturated the Nvidia 1 Gbit link but without buffering or any other hick ups.


At Jellyfins admin section I have added all RFC1918 networks to be treated as LAN.



How can I determine if Jellyfin will always use direct streaming instead of converting it to a lower bitrate?

You can turn off transcoding for the user you want to test with. Then you can use the Dashboard to observe behavior. If your client is compatible (Shield is a good option for compatibility) it will direct stream.

4K UHD Bluray has a max bitrate of 128Mbps, so unless you're streaming 8K then the max limit of 200Mbps is more than adequate.

However if you're really speaking of uncompressed 4K, then the data rates will be well over the 1Gbit you have (approx 5Gbit/sec)

Would that be a global setting?
For example if I am abroad I would like to downsample on my mobile device

Again bringing up the topic regarding transfer speed:

On Android TV the maximum setting is currently 200 Mbit/s - some of my 4K videos have around 20 Mb/s which would be 1600 Mbit/s.

Still unsure if Jellyfin will then convert the video down to match the 200 Mbit limit or not.

20Mb/s = 20Mbit/sec
If you meant 20MB/s then this is only 160Mbit/s (not 1600, as its 8bits to a byte)
If these are 4K UHD Bluray movies the max bitrate is 144Mbit for newer discs and 128Mbit for the normal sized discs, so even if you have a remux there is no way it gets past 200Mbit/sec.
If these are 4K movies you have made yourself, then i would probably suggest re-encoding them to a more normal bitrate.

Yeah sorry - seems I am no longer able to do simple mathematics. 
1 Byte = 8 Bits -> 1 Megabyte = 8 Megabit and so on.
