Path for the ffmpeg binary is not correct in jellyfin.sh

[hobby-lc]

The ffmepg binary is not located in the folder "/usr/share/ffmpeg" for Ubuntu 22.04. Jellyfin service will start normally (with error message only) until the need of transcoding the video during play. FYI.

It would be better to use "$(which jellyfin)" to pass the ffmepg binary location in the jellyfin.sh.

And, it seems that Jellyfin called "ffprobe" instead of "ffmpeg" sometimes during play.

https://forum.jellyfin.org/t-ffmpeg-path-jellyfin-10-8-13?pid=11058#pid11058 According to the above discussion, adding the following lines in encoding.xml should fix the ffprobe problem: (it seems that the cmdline option "--ffmpeg" will modfiy the "EncoderAppPathDisplay" only)

`/path/to/bin/ffmpeg

/path/to/bin/ffmpeg` Thank you very much for jellyman. Please consider adding an option for using the jellyfin-ffmpeg.

Unfortunately your solution would not work, for example this is my output on my system for that.

echo $(which jellyfin)
which: no jellyfin in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/var/lib/snapd/snap/bin)

However it would be better perhaps to use $(which ffmpeg). Maybe that's what you meant?

Sorry for the typo, and yes I mean '$(which ffmpeg)' for locating the ffmpeg binary path.

I still haven't tested this on my system, I would like to make sure this works in every situation on all the distros I mentioned I tested it on before continuing. As for specific Ubuntu support for jellyfin-ffmpeg, anyone with a reasonable understanding of linux would easily be able to install jellyfin-ffmpeg on their ubuntu machine with my script. I'm just not so sure that it's completely necessary to add code specifically for ubuntu and that specific use case of their version of ffmpeg. Feel free to write up some code to include the automatic installation for jellyfin-ffmpeg as a pull request, and I may merge it.
