I'm unable to transcode a video file to webm because my machine isn't able to find libvorbis. When I run the following command:
ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360 -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm
I get the error
Unknown encoder 'libvorbis'
I already have libvorbis installed on my machine, though (When I try "brew install libvorbis, it tells me: Warning: libvorbis-1.3.3 already installed).
How can I solve this problem?
Here is the full log:
ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360 -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm

Edit 2020:
Homebrew now installs libvorbis by default, so you can just run:
brew install ffmpeg
If you're using Homebrew, try this:
brew install ffmpeg --with-libvorbis
...or, if you've already tried installing ffmpeg with Homebrew...
brew reinstall ffmpeg --with-libvorbis
If you want libvpx, too:
brew reinstall ffmpeg --with-libvpx --with-libvorbis

Your ffmpeg build is not compiled with --enable-libvorbis
which is required if you want libvorbis support in ffmpeg
, but you have some options:
Note: Vorbis has been made obsolete by Opus, so consider using libopus instead–especially if you are encoding to VP9/VP8 (WebM).
This is an easy option. Already compiled macOS builds of ffmpeg are available and come with libvorbis support. You can just download the executable and optionally put it in /usr/local/bin
.
The Hombrew core FFmpeg formulae contains support for libvorbis by default (as of 2019-03-01). First, install Homebrew, then run:
brew install ffmpeg
However, the core formulae no longer supports additional, non-default options such as --with-aom
, so if you want to customize it see the option below.
This is a third-party tap that provides a Homebrew formula with lots of additional options you can enable. First, install Homebrew, then:
Uninstall ffmpeg
if you installed it from Homebrew core:
brew uninstall ffmpeg
Then install ffmpeg from homebrew-ffmpeg:
brew tap homebrew-ffmpeg/ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg
For more options and info see homebrew-ffmpeg.
For complete instructions for manually compiling see FFmpeg Wiki: macOS.

Homebrew stopped supporting the --with-libvorbis
option in late 2018. Precompiled binaries containing libvorbis for Linux, macOS and Windows here: https://ffmpeg.org/download.html

The problem was fixed with the suggestion here of rebuilding ffmpeg using:
./configure --disable-encoder=vorbis --enable-libvorbis; make; make install
