Very slow transcoding - Akeldema - 2023-09-14

I have been struggling for a few days now to work out the cause of my transcoding performance issues.
Most shows have a noticeable delay before they start playing 15 to 30 seconds, with movies taking anywhere up to 7 to 10 minutes before playback begins.

I have tried no hardware acceleration along with AMD AMF and VAAPI, VAAPI may have been the fastest but by far the poorest quality once playback started.

Below is one of the ffmpeg logs for the worst example of this, it takes so long to start that it creates a few dozen logs, but they all seem to contain basically the same data.

hardware of the machine doing the transcoding is a AMD 5800x and a AMD RX 7900 XTX

Any input would be much appreciated as this is driving me crazy.

RE: Very slow transcoding - TheDreadPirate - 2023-09-14

Which client are you using. It looks like the issue is with the subtitles and fonts.

RE: Very slow transcoding - Akeldema - 2023-09-14

I have been using the web client in chrome.
your question actually spurred me to try a couple of other clients, both the Official desktop client and Edge will play without transcoding, never occurred to me that chrome was just being the problem.

Is there any way to get chrome to be able to play these files without transcoding, or should I just forget about using chrome and move across to either Edge or the Official Desktop app

RE: Very slow transcoding - TheDreadPirate - 2023-09-14

Your system SHOULD be able to transcode, no problem. I would need to see your main jellyfin log to figure out why it wanted to transcode and if there are any other errors that aren't in the ffmpeg log.

RE: Very slow transcoding - Akeldema - 2023-09-14

This is the main log_20230915.log file up until the point playback resumed. 
If you need a larger log let me know, this is from a fresh restart of the server.

RE: Very slow transcoding - TheDreadPirate - 2023-09-14

Your log looks normal. Including the fact that ffmpeg exited with code 0 (no problems). How much of this guide did you follow?

https://jellyfin.org/docs/general/administration/hardware-acceleration/amd/#windows-setups

RE: Very slow transcoding - Akeldema - 2023-09-14

I believe when I first set it up I followed the documentation, I'll go over it from scratch tomorrow and see if it yields any improvements.

RE: Very slow transcoding - Akeldema - 2023-09-15

I have gone back over the documentation and verified that it is all set up accordingly.

the only thing of interest I noticed while doing is while Jellyfin is sitting there frozen FFMPEG is hitting my HDD at its maximum read speed while the GPU is inactive, once the file starts playing the GPU kicks in and the encoding is obviously being done by the GPU.

Now I obviously have no understanding of the innerworkings of FFMPEG, but if its sitting here for 8 minutes reading the same file at 210MB/s there's something not quite right going on.

RE: Very slow transcoding - TheDreadPirate - 2023-09-15

The only thing that makes sense to me is the many TTF based subtitle tracks in your media. There's gotta be some sort of interaction or rendering with the fonts going on. Do you happen to have any media that DOESN'T have TTF (custom fonts) subtitles? What happens when you try to transcode those?

RE: Very slow transcoding - Akeldema - 2023-09-15

I think pretty much everything I have has .ASS subtitles, the one series I know for sure that does not have them has a strange display issue in chrome/jellyfin for the subtitles, but does not need to transcode.
FFMPEG log for the non .ASS series https://pastebin.com/GEAkzZeM sorry for the pastebin, the log was too big for a comment.
