Transcoding on WebOS with PGS + TrueHD

[sonyci]

Hello,

I activated the "Experimental PGS rendering" option in Jellyfin. With that option, I can direct stream a mkv file with DV/AC3 audio and PGS subtitles activated. Without the option, activating the PGS subtitles activates transcoding.

However, if I select an audio track which is TrueHD Atmos (I have the passthrough option activated too, as my AVR is compatible with TrueHD Atmos), I get transcoding when the PGS subtitles are activated.

This means I have to choose:
- either use .srt to be able to play DV/TrueHD content without transcoding (but I prefer PGS)
- or use AC3 instead of TrueHD to be able to play DV/PGS content without transcoding

I would expect that it should be possible to play DV/TrueHD/PGS content without transcodig, as it seems those options when activated individually seem to work. Am I missing something here?

Submit a github issue. This sounds like a bug.

Shouldn't it be https://github.com/jellyfin/jellyfin-webos ?

I forgot to say I am using the native Jellyfin player on webos (LG G4).

Thank you, yes. The webos repo.

I will do more tests tonight and get around posting ffmpeg logs on the issue if that helps.
