AppleTV 4th Gen - Jellyfin/Swiftfin Not Transcoding Properly

[i-am-the-arm]

Describe the bug

I just set up HWA on my Jellyfin server using a Quadro p620. So far, so good; however, I just tried to play a tv show episode and it behaves as if Jellyfin doesn't even try to transcode on the AppleTV; sits at a black screen and eventually moves onto the next episode which also sits on a black screen. I tried the same video on my iPhone and it does transcode. Running ffprobe, here is a comparison of a working and not working file (stripping out stuff I didn't think was relevant):

Transcoding	Not Transcoding
"codec_name": "hevc",	"codec_name": "h264"
"codec_long_name": "H.265 / HEVC (High Efficiency Video Coding)",	"codec_long_name": "H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10"

"codec_type": "audio",	"codec_type": "audio",
"sample_rate": "48000"	"sample_rate": "48000"
"channels": 6,	"channels": 6

I have also selected both HEVC and H264 under the "Enable hardware decoding for" section. I noticed that when I play the video on my AppleTV, I get a FFmpeg.DirectStream log whereas when playing via my iPhone, I see a FFmpeg.Transcode log file. I don't see any errors in the DirectStream log file, but noticed it says "SupportsDirectStream":true,"SupportsDirectPlay":true, so again, I'm curious why it's not attempting to transcode.

As a final mention, running nvidia-smi shows a process running for the "working" video but No running processes found for the other.

Hoping to get some direction without having to re-encode all these files. Please let me know if I can send anything else that would help diagnose.

The issue is likely related to the device profile, which was pushed a while ago, but the app on tvOS hasn't been updated yet.

The issue is likely related to the device profile, which was pushed a while ago, but the app on tvOS hasn't been updated yet.

Can we get an indication of when the app on tvOS will be updated? I have the same AppleTV as the reporter, and the native client isn't working for much of my library.

Note: Update is provided in #1294.
