Building on Fedora

[rishubn]

Hi,

Can this repo be built without any changes for different platforms I.e., fedora or RHEL? If not, what debian/ubuntu specific changes have been made?

Thanks,

[nyanmisaka]

All you need is to clone this repo and apply all patches under debian/patches folder and configure ffmpeg with following options to satisfy jellyfin’s minimal requirements: https://github.com/jellyfin/jellyfin-ffmpeg/blob/jellyfin/debian/rules

Here’s the PKGBUILD file for Arch linux:
https://aur.archlinux.org/packages/jellyfin-ffmpeg5

Thanks for the guidance! I managed to compile 5.1-2 with the following options (Fedora 36):

I had to remove --enable-lto is this flag necessary? Not sure if it affects the binary or just compilation time

[nyanmisaka]

No. It's LTO(link time optimization), which affects the output binary and slow down the compiling speed.

Did you use Fedora build script to build the package? Any chance you can share it?

[rishubn]

@nyanmisaka Ah ok, so LTO will make ffmpeg runtime slower as well?

I did not build an RPM as I am not familiar with the packaging; however I can write a short summary of what I did on the jellyfin forums once I get everything stable.

[nyanmisaka]

It should make ffmpeg faster a little bit at runtime.

Note: I discovered this:

https://github.com/chenxiaolong/jellyfin-ffmpeg-fedora

It mostly worked for me to make an rpm. I had to add rpmfusion setups to my box, and I had a problem with nvenc. But it is a great place to start. The author notes that this could be included in Jellyfin itself.
