Hope this gives some info: https://paste.kodi.tv/bofejupiku.kodi

I first played the file normal, then enabled forced Transcoding and played the file again.

This is the log from the Jellyfin server: https://paste.kodi.tv/fekazizola

Are you using native mode?  I'm genuinely not sure if transcoding works in native mode, since it's entire point is to basically give a middle finger to the server and do what it wants anyway.  I've never tried it myself, never seen the point to using native mode.  I also see that you have ssl verification turned off.  This shouldn't be causing any weirdness, but it's not entirely outside the realm of possibility.  Possibly more concerning is that you have a lot of errors when trying to download subtitles from the server.  I'm not sure what would be causing that

Nope using addon mode, but yeah I tried both.

When searching for issues I saw somebody say Native is a hack and that it is better to use the addon mode.
So I tried that and surprisingly it works quite fast.

I also tried direct to the IP and port instead of through Synology’s reverse proxy, the same issue.

your jellyfin server is installed on a Synology NAS?
if yes, what version and how was it installed?

Yes, it is running version 10.8.13 within docker.
Transcoding working perfect within a webbrowser or iPhone/iPad apps.

i ask because if it is a forked or 3rd party install the addon may be requesting transcoding that is broken or unsupported on the server (which it expects to work in the official jellyfin)
and because mcarlton is unable to reproduce with official jellyfin
and because there are also 'synology' community versions running around

and because each client requests transcoding differently


RE: Transcoding in Kodi - Theetjuh - 2024-02-02

I don’t mind, I am as intrigued to why it isn’t working.
So from that point I’m an open book .. ask and I shall provide Grinning-face


RE: Transcoding in Kodi - tmsrxzar - 2024-02-02

i tried to break mine to match but i'm not able to, it's working for me

Jellyfin for Kodi (not jellycon)

base addon settings
- cinema mode off
- force http playback on
- Force transcode Off
- Enable External Subs On
- Preferred video codec h264
- Preferred audio codec aac

tried to set my max bandwidth to 10Mbit, it worked so i changed it back to 1000 (default)
then tried changing Transcode H265/HEVC to On and it worked
so i'm not sure how to break mine in order to tell you whats broken

try changing the Preferred codecs, this is what it is asking the server to Encode "To"


RE: Transcoding in Kodi - tmsrxzar - 2024-02-02

from the log it started having issues at 16th subtitle, maybe ffmpeg isn't able to extract 24 subtitle tracks fast enough

i don't have any files with 24 subtitle tracks to test, suggest removing the subs and test with that

ffmpeg -i (infile) -map 0:v -map 0:a -c copy (testfile).mkv


RE: Transcoding in Kodi - Theetjuh - 2024-02-02

I have used the linuxserver/jellyfin docker image, I am now building a new database with the jellyfin/jellyfin docker image.
Just to be sure that is not the issue … so that will take quite some time to get back in business and test again.

I have tried multiple files, also with only english subs and 1080p video.

That many subtitles is normally also no issue for Kodi and that uses quite an old ffmpeg from what I know.
Kodi 21 will make a jump to version 6 instead of 4 from what I heard.
