Description

The char type with gcc on ARM defaults to unsigned instead of signed on x86. Consequently the VideoHardwareDecoder flag is not working as intended on ARM (result is a black screen with MPEG2/VDPAU).
Adding -fsigned-char to CXXFLAGS and CFLAGS in the Makefile resolves the problem.

Thank you for your work.

This path should eleminate the type-limits compiler warnings and solve the arm unsigned char issue.

This is mostly fixed in current git, but I believe there's one more of these changes still needed:

diff --git a/softhddev.c b/softhddev.c
