[vlc-devel] [PATCH] taglib: Enable caching on the IOStream

Hi,

Using cache only essentially optimises for half-assed plugins that don't implement streaming like the libsmbclient-based one, but *breaks* slow bandwidth inputs even with properly implemented plugins like HTTP or FTP, which require prefetch.

I don't think we should optimise for bugs if it means breaking something else.
