SOLVED: Playback Error causing 0 videos to play

[Link of Hyrule]

Hey all, been using Jellyfin for a bit, but it stopped playing some videos, then while trying to troubleshoot the issue, a reinstall seemed to completely break it. The things it used to play are now:

Playback Error
Playback failed due to a fatal player error.


Restarts do nothing, and it was working originally without hardware transcoding, I believe I've set it up properly now. I'm using an older laptop (ASUS X550Z) as a home server. The drive is new, and the Ubuntu server OS was recently reinstalled after a HDD upgrade. I am new to Linux and having trouble troubleshooting for myself.

Your laptops CPU/iGPU is not fast enough for CPU transcoding and doesn't have the capability to hardware accelerate transcoding.

You either need to pre-transcode to avoid transcoding on the fly or upgrade the server, which is less expensive than you think.

Why was it able to play beforehand, but now it can't do anything? Anyway to get it back to a usable state? Also, how could I go about pre-transcoding?

[TheDreadPirate]

Can you share your full jellyfin logs via pastebin?

Also, I had VLC transcode a video for me, and no dice.

Can you directly link the pastebin? I'm at work and pastebin is blocked. I use my Google Cloud VM to circumvent that but I need a direct link to wget the log file.

Due to size, I had to split it into parts. My son (autistic 16 year old) has been trying like a mad man to watch something, so I'm sorry about the size:
Part 1
Part 2
Part 3

ffmpeg is missing.

Code:

[2024-07-05 00:41:06.289 +00:00] [ERR] Error processing request. URL "GET" "/videos/70534b1a-3a59-0ecc-1b24-2cb4e47f9ecf/live.m3u8".
System.ArgumentNullException: Value cannot be null. (Parameter '_mediaEncoder.EncoderPath')

What are the contents of /etc/jellyfin/encoding.xml? Is there a value for this line?

Code:

<EncoderAppPathDisplay>/usr/lib/jellyfin-ffmpeg/ffmpeg</EncoderAppPathDisplay>

Is jellyfin-ffmpeg installed?

Code:

sudo apt list --installed | grep ffmpeg

I did install it, but let me do it agsin.

[TheDreadPirate]

Is the EncoderAppPathDisplay set in /etc/jellyfin/encoding.xml?

Also make sure you install jellyfin-ffmpeg instead of plain ffmpeg.

Code:

sudo apt install jellyfin-ffmpeg6
