SOLVED: Still using 10.8.9

[finicky6457]

I tried putting one of my MPEG2 test videos in TS (originally in MKV) and it still direct played on my 4800X.

Can you install the playback reporting plugin on 10.10 and replicate the issue with your TS files?  That plugin should print out why it is being transcoded.

Or you can have the Dashboard open on your PC and click on the "i" icon for the Roku playback and it should tell you why it is being transcoded.

Ok, I think this may help show what's going on....

Jellyfin 10.8.9

Code:

Remuxing
The media is in an incompatible file container (MKV, AVI, WMV, etc) but both the video stream and audio stream are compatible with the device. The media will be repackaged losslessly on the fly before being sent to the device.


Remux uses very little processing power with a completely lossless media quality.

Jellyfin 10.10.0

Code:

Transcoding
The media is being converted into a format that is compatible with the device that is playing the media.
Framerate: 28fps

9.5 Mbps TS HEVC AC3


Reason for transcoding:
The container is not supported

But on my Roku it direct plays MPEG2 in TS, also with AC3 audio. Which should be identical do your files.

What specific model Roku do you have? And the Roku OS and Jellyfin app version.

Roku Ultra (4800X)
Model 4802X
Roku OS 14.0
Jellyfin Roku app version 2.2 Build 1

I think I figured it out. For whatever reason, Jellyfin behaves differently depending on which hardware acceleration mode is enabled.

When QSV is select on my server, my Roku client, also a 4802X, will direct play my MPEG2/AC3 in TS video. But if I select "none" for hardware accleration, to match your setup, Jellyfin will transcode it.

This is definitely a bug. I will go ahead and submit a bug report with my findings.
