No OPUS audio transcoding?

[fire_jellyfin]

Hi, I have a collection of music video (h264) clips that contain audio with OPUS codec. They play fine on a PC.
I am not able to play those videos (with sound) on TV from the Jellyfin DLNA server.. The television can not install the Jellyfin app, therefore playback is done through DLNA. Direct playback (from USB) of video with the OPUS audio codec is not supported on this Panasonic Television. The video is played, but without sound.

Jellyfin is configured with a profile for the television. Unsupported video codecs are transcoded correctly, but native playable video codecs with unsupported OPUS audio codec are not transcoded. Jellyfin is aware of the unsupported audio codec (see journal below), but it streams the media without any transcoding. As a result I am able to see the video playing but without sound.

I fail to see why Jellyfin does not transcode these media files with opus audio and like to find a solution for it. Any help is greatly appreciated.

Opus is widely used now and is here to stay... I would still like to get a little help or thought with this issue.

Setting the condition limit for opus audio ridiculously low or at 1 channel also won't trigger Jellyfin to start transcoding the media. It keeps streaming it as directplay and does not produce any log file.

This appears to be a known issue for a while.

hmmm i see, guess more people will bump into this one with opus being so popular. Hopefully a real fix will be found. I started using Jellyfin in 2021 and can't remember having this issue with Emby. Probably somewhere on the line it got broken.
