Please describe your bug

I'm finding that Jellyfin is transcoding video content while listing the reason for transcoding as Audio Codec Not Supported.

If it's only the audio codec that is causing issues it should probably be only encoding it and not the video as well.

I'm attaching a section of my logs where this is occurring and one interesting thing I've noticed is that despite using the Jellyfin app on Roku the Device profile information seems rather sparse and missing some things that I believe the Roku supports codec-wise.

Jellyfin Version

10.7.7

As I mentioned on #7439, I still see this (as of yesterday's nightly) with 'downmix to stereo' option on, so it seems recent changes in this area have not totally fixed these problems?

This is still present in 10.8.8, so 10.8.2 doesn't seem to fix this:

What's also interesting is it transcodes to H.264, even thou HW encoding to HVEC is enabled and supported by my nV GPU.

I faced the same problem on 10.8.8 when playing on Jellyfin Android TV app. I have enabled encoding in HEVC. When "Allow video playback that requires transcoding" is selected, the HDR data is lost and the video is encoded in h264 and color space changes from bt2020nc/bt2020/smpte2084 to bt709. I had just selected the option to downmix to stereo as my speaker is stereo and not 5.1. The file doesn't play in exoplayer. It plays on libvlc but in SDR. When I play it through external player like NOVA, it plays correctly in Dolby vision.

log snippet
Stream mapping:
Stream #0:0 -> #0:0 (hevc (native) -> h264 (h264_nvenc))
Stream #0:1 -> #0:1 (eac3 (native) -> aac (libfdk_aac))

I see this in my environment also. Also running on Kubernetes. I also noticed that the UnsupportedAudio seems to be incorrect, since viewing the file information seems to confirm that the audio is a common format and should be well supported.

I have issues with direct play generally and transcoding seems to be considerably more reliable when running on Kubernetes. I've asked several folks in the communtiy channels and they all seem to think that the files in question should play without transcode, so I wonder if there is something more fundamental going on here. Transcoding would use ffmpeg to open and read the files, which would be potentially different than the method that the .NET code uses to open the file.

I just run into this issue with Jellyfin Server 10.11.0 and Jellyfin Roku 3.0.10 on a Roku Streaming Stick 4K (3820x).

Video: AV1 SDR in MKV container
Audio: Surround 5.1 - DTS-HD MA

Jellyfin says that the reason for transcoding is only the audio codec, but then it goes on and transcodes to H264 + MP3.

This Roku Stick / Client can successfully play AV1 SDR in MKV with Flac-24bit, so it is really just the audio codec.

Did I misconfigure something or is this (still) a bug?

This issue was resolved in the Web client years ago.

Your issue is https://github.com/jellyfin/jellyfin-roku/issues/433, and the Roku client doesn't support AV1 in HLS. Roku needs to update its OS to add support, and then the Roku client needs to be updated accordingly.

This issue was resolved in the **Web client** years ago. Your issue is https://github.com/jellyfin/jellyfin-roku/issues/433, and the **Roku client** doesn't support AV1 in HLS. Roku needs to update its OS to add support, and then the Roku client needs to be updated accordingly.

Your issue is jellyfin/jellyfin-roku#433, and the Roku client doesn't support AV1 in HLS. Roku needs to update its OS to add support, and then the Roku client needs to be updated accordingly.

Thanks, I just found that issue too and took the time to read through it.
But again, the very same device / client / server combo plays AV1 SDR in MKV with Flac-24bit fine. AFAIK this is using HLS too?

But I should probably switch over to the other issue, thanks!

That's direct play, because the video and audio formats are all supported by the device.

If the audio format isn't supported, transcoding occurs, in which case the HLS protocol is used. In this case, Roku is only capable of H264, HEVC, and VP9, which is why you see transcoding of the video.
