Hello,

I got the very latest svn head, then tried to compile.
But, I got errors;

Strange, is this on Linux? Either way I expect it is fixed by disabling these files as they caused issues on non-Linux systems, so they are disabled for now.
They won't be interesting for the vast majority of users anyway.

Yes, on Linux.

I executed 'svn up', then the configure script was updated.
This solved the problem.

Thanks,

That makes me wonder why MPlayer _still_ uses the frankenstein approach
of an "in-tree" FFmpeg with its build system partially replaced. It
seems to cause regressions every other week.

Wouldn't it be much easier to default to an external FFmpeg?

Only changing the default would mean it still needs to be fixed, thus not any less effort...
In exchange, it would mean having to do a proper version check and supporting multiple FFmpeg versions, which is quite some effort.
Though that doesn't mean that it might not make sense to change the default anyway.
