Compiling JM14.1 for CBE

• Compiler requires switch -fsigned-char to set default signedness of char to signed. This is an issue between x86 and PPC which use signed and unsigned char respectively, information on signed char here: An Introduction to GCC
• Don't know yet if these flags from JM Makefile are needed: -std=gnu99 -pedantic -ffloat-store -fno-strict-aliasing -m32

Video Quality

• Example Cisco jitter target, 10ms
