* qatar/master: h264: K&R formatting cosmetics s3tc.h: Add missing #include to fix standalone header compilation. FATE: add capability for audio encode/decode tests with fuzzy psnr comparison FATE: allow a tolerance in the size comparison in do_tiny_psnr() FATE: use absolute difference from a target value in do_tiny_psnr() FATE: allow tests to set CMP_SHIFT to pass to tiny_psnr FATE: use $fuzz directly in do_tiny_psnr() instead of passing it around Conflicts: libavcodec/h264.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
