[FFmpeg-user] Unknown decoder 'libvpx-vp9'

[Ronnie Roller]

I'm built ffmpeg 4.1 with libvpx 1.8.0.

Running "ffmpeg -vcodec libvpx -i vp9a.webm -pix_fmt rgba out/image_%d.png"
doesn't work because I need to use the libvpx-vp9 codec.

Running "ffmpeg -vcodec libvpx-vp9 -i vp9a.webm -pix_fmt rgba
out/image_%d.png" results with:

Unknown decoder 'libvpx-vp9'

I can't find any resources that show how to get the decoder 'libvpx-vp9' to
work. It does work if I brew install ffmpeg (but brew is not an option for
me).

Any idea how to get the libvpx-vp9 decoder enabled?

Here's how I built:

cd libvpx-1.8.0 && \
./configure \
make && \
make install

./configure \
    --enable-gpl \
    --enable-libx264 \
    --enable-libx265 \
    --enable-libwebp \
    --enable-librsvg \
    --enable-libvorbis \
    --enable-libvpx \
    --disable-network && \
make -j12 && \
make install-progs
