在ubuntu上安装ffmpeg时出错：使用pkg-config找不到opus

Question

When I try to install ffmpeg on my ubuntu 14.10 machine, I keep getting this:

ERROR: opus not found using pkg-config

at this step :

PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
  --prefix="$HOME/ffmpeg_build" \
  --extra-cflags="-I$HOME/ffmpeg_build/include" \
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  --bindir="$HOME/bin" \
  --enable-gpl \
  --enable-libass \
  --enable-libfdk-aac \
  --enable-libfreetype \
  --enable-libmp3lame \
  --enable-libopus \
  --enable-libtheora \
  --enable-libvorbis \
  --enable-libvpx \
  --enable-libx264 \
  --enable-nonfree

I've followed all the previous installation steps and it went all successful. I'm really new to Ubuntu. Could anybody give me a hint?

Answer 1

这对我有帮助......

apt-get install libopus-dev

Answer 2

我通过安装opus-devel包在Fedora上解决了这个问题。

Answer 3

我将其添加到./configure行，它似乎解决了它：

--pkg-config-flags="--static"

1- first start fresh again and delete what you have done: (copy and in terminal press right button of the mouse to paste )

rm -rf ~/ffmpeg_build ~/ffmpeg_sources ~/bin/{ffmpeg,ffprobe,ffplay,ffserver,vsyasm,x264,x265,yasm,ytasm}
sudo apt-get autoremove autoconf automake build-essential cmake libass-dev libfreetype6-dev \
  libmp3lame-dev libopus-dev libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev \
  libvorbis-dev libvpx-dev libx264-dev libxcb1-dev libxcb-shm0-dev ibxcb-xfixes0-dev mercurial texinfo zlib1g-dev
sed -i '/ffmpeg_build/c\' ~/.manpath
hash -r

2- now update your server :

sudo apt-get update 

3- install build tools for your server to build ffmpeg :

sudo apt-get install build-essential

4- now follow the steps in this link

Answer 5

This was the only code worked to me

PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH
