	Merge remote-tracking branch 'qatar/master'
* qatar/master: indeo3: add parens around some macro arguments h264: use proper PROLOGUE statement for a function using 8 registers. doc: Update sample Vim config with suitable (function) indentation settings. dv: Merge dvquant.h into dvdata.c where all other DV tables reside. dv: Move static tables only used in one place to where they are used. graphparser: set next to NULL on an entry extracted from inputs list doc/filters: update documentation. avconv: flush decoders immediately after an EOF. avconv: send EOF to vsrc_buffer. avconv: reindent. Conflicts: doc/filters.texi ffmpeg.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
