How to use ffmpeg to convert midi to ogg

[ToddAndMargo]

Hi All,

Fedora 30
ffmpeg-4.1.3-2.fc30.x86_64

How do I use ffmpeg to convert midi to ogg?

$ ffmpeg -i Bless-The-Lord.midi -vn -acodec libvorbis Bless-The-Lord.ogg
...
Bless-The-Lord.midi: Invalid data found when processing input

Many thank,

You don't, midi is not an audio format.  You need to use something like 
timidity to generate the instrument sounds.  I think it can directly 
write to vorbis as well.

I don't remember having tried that ever, but there's even a Wiki for
it: fluidsynth

How to convert MIDI to MP3/OGG

Simple command lines to convert midi to ogg:

$ fluidsynth -nli -r 48000 -o synth.cpu-cores=2 -T oga -F example.ogg
/usr/share/soundfonts/FluidR3_GM.sf2 example.MID
"
from:
https://wiki.archlinux.org/index.php/FluidSynth

Note the dependencies for the package: you might need
FluidR3_GM*, maybe twolame.
More on the Wiki.

someth. like:
dnf -C whatprovides \*FluidR3_GM\*
dnf -C repoquery -l fluid-soundfont-gm

HTH, and good luck!
Wolfgang

Thank you!

I already installed fluid-soundfont-gm to get VLC to work
with MIDI, so this should be ...
