Shield Pro 4K HDR AV1

[levogevo]

Hello all. I have an Nvidia Shield Pro 2019 that exhibits on/off weird behavior. In short, it tries to direct play (4K HDR) AV1 streams when the server should be transcoding them.

I have attached logs that capture the following:
-Playing and transcoding using the "sideloaded" Jellyfin mobile Android client apk ("correct" behavior)
-Attempting playing and not transcoding using the Jellyfin Android TV "default" client (it should be transcoding)
-Server log capturing both (first mobile, then TV client)

I say on/off because some 4K HDR AV1 files do transcode, and others do not. When it does not transcode (TV client), I simply get a "player encountered error" and cannot play the video file.
I also know it's not a server issue, because when I use the mobile client, the transcode is without issue, so something in the polling of the client abilities in the TV app is giving the green light to direct play when it should not be.

Any suggestions would be great.

Are you using 10.9 unstable?  It looks like you are transcoding to AV1 when playing on the Shield.  Which shouldn't be the case.

Make sure you are on the latest unstable build.  If the problem persists turn on debug logging and replicate the problem.  Debug logging will log the device profile reported by the client, which includes codec compatibility.
