I'm trying to checkout libvpx but I get the error below.
sudo git clone http://git.chromium.org/webm/libvpx.git
Initialized empty Git repository in /opt/ffmpeg/sources/libvpx/.git/
warning: remote HEAD refers to nonexistent ref, unable to checkout.
cd libvpx/
git branch -a
<nothing>
I've even tried to checkout the master branch specifically but still nothing.
sudo git clone http://git.chromium.org/webm/libvpx.git -b master
Initialized empty Git repository in /opt/ffmpeg/sources/libvpx/.git/
warning: Remote branch master not found in upstream origin, using HEAD instead
