Use git clone --depth 1 for faster clones about mpv-build

The problem with this is that with --depth=1 the tags (apparently) do not match up anymore, so I'm not sure if this could work with the current scripts. If someone could verify whether this happens and/or has a workaround, that would be welcome.

Or maybe the problem is that it doesn't fetch all refs (so we can't list them locally). Do you have any interest in getting this to work?

For me,

git clone --depth 1 https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg && git tag

returns nothing at all.

It seems that the fundamental problem is that git has no way of of cloning only metadata. For example

git log remotes/origin/master

will not do what you might expect/want in a shallow clone. There is a relevant stackoverflow question essentially confirming this.

I guess you'd want to git clone/pull the entire repo if you want to use a specific release. If you just want to use HEAD, git clone --depth 1 should work.

this creates all kinds of problems when switching from one to the other

Could run git pull --tags if switching to to a specific release?

Actually, if you are building from a release, the script should download the *.tar.gz and extract them. If building from master, git clone.
