* qatar/master: (25 commits) rv40dsp x86: MMX/MMX2/3DNow/SSE2/SSSE3 implementations of MC ape: Use unsigned integer maths arm: dsputil: fix overreads in put/avg_pixels functions h264: K&R formatting cosmetics for header files (part II/II) h264: K&R formatting cosmetics for header files (part I/II) rtmp: Implement check bandwidth notification. rtmp: Support 'rtmp_swfurl', an option which specifies the URL of the SWF player. rtmp: Support 'rtmp_flashver', an option which overrides the version of the Flash plugin. rtmp: Support 'rtmp_tcurl', an option which overrides the URL of the target stream. cmdutils: Add fallback case to switch in check_stream_specifier(). sctp: be consistent with socket option level configure: Add _XOPEN_SOURCE=600 to Solaris preprocessor flags. vcr1enc: drop pointless empty encode_init() wrapper function vcr1: drop pointless write-only AVCodecContext member from VCR1Context vcr1: group encoder code together to save #ifdefs vcr1: cosmetics: K&R prettyprinting, typos, parentheses, dead code, comments mov: make one comment slightly more specific lavr: replace the SSE version of ff_conv_fltp_to_flt_6ch() with SSE4 and AVX lavfi: move audio-related functions to a separate file. lavfi: remove some audio-related function from public API. ...
