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
warning: remote HEAD refers to nonexistent ref, unable to checkout.
Because the remote git repositories not create the master branch. You can use git branch -r to look the other branch, and use git checkout -b xxx origin/xxx to checkout a remote branch code. Or try git help symbolic-ref for more information.
