* qatar/master: swscale: make yuv2yuv1 use named registers. h264: mark h264_idct_add8_10 with number of XMM registers. swscale: fix V plane memory location in bilinear/unscaled RGB/YUYV case. vp8: always update next_framep[] before returning from decode_frame(). avconv: estimate next_dts from framerate if it is set. avconv: better next_dts usage. avconv: rename InputStream.pts to last_dts. avconv: reduce overloading for InputStream.pts. avconv: rename InputStream.next_pts to next_dts. avconv: rework -t handling for encoding. avconv: set encoder timebase for subtitles. pva-demux test: add -vn swscale: K&R formatting cosmetics for SPARC code apedec: allow the user to set the maximum number of output samples per call apedec: do not unnecessarily zero output samples for mono frames apedec: allocate a single flat buffer for decoded samples apedec: use sizeof(field) instead of sizeof(type) swscale: split C output functions into separate file. swscale: Split C input functions into separate file. bytestream: Add bytestream2 writing API. The avconv changes are due to massive regressions and bugs not merged yet.
