[libdvdcss-devel] Tag 1.4.0 : libdvcss 1.4.0 [with patch in-line]

[Jörg-Volker Peetz]

Setting the environment variable DVDCSS_CACHE described in libdvdcss.c does not
work as expected: any path set in the environment variable is ignored and no
caching files are written.

In the function set_cache_directory() the local variable psz_cache containing
any non-void content of DVDCSS_CACHE is not written to the structure dvdcss.
Something like the patch below might be needed, therefore.

Regards,
Jörg-Volker.
