* qatar/master: v410dec: Implement explode mode support zerocodec: fix direct rendering. wav: init st to NULL to avoid a false-positive warning. wavpack: set bits_per_raw_sample for S32 samples to properly identify 24-bit h264: refactor NAL decode loop RTMPTE protocol support RTMPE protocol support rtmp: Add ff_rtmp_calc_digest_pos() rtmp: Rename rtmp_calc_digest to ff_rtmp_calc_digest and make it global swscale: add missing HAVE_INLINE_ASM check. lavfi: place x86 inline assembly under HAVE_INLINE_ASM. vc1: Add a test for interlaced field pictures swscale: Mark all init functions as av_cold swscale: x86: Drop pointless _mmx suffix from filenames lavf: use conditional notation for default codec in muxer declarations. swscale: place inline assembly bilinear scaler under HAVE_INLINE_ASM. dsputil: ppc: cosmetics: pretty-print dsputil: x86: add SHUFFLE_MASK_W macro configure: respect CC_O setting in check_cc Conflicts: Changelog configure libavcodec/v410dec.c libavcodec/zerocodec.c libavformat/asfenc.c libavformat/version.h libswscale/utils.c libswscale/x86/swscale.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
