* qatar/master: libavutil: add utility functions to simplify allocation of audio buffers. libavutil: add planar sample formats and av_sample_fmt_is_planar() avconv: fix segfault at EOF with delayed pictures pcmdec: remove unneeded resetting of samples pointer avconv: remove a now unused parameter from output_packet(). avconv: formatting fixes in output_packet() avconv: declare some variables in blocks where they are used avconv: use the same behavior when decoding audio/video/subs bethsoftvideo: return proper consumed size for palette packets. cdg: skip packets that don't contain a cdg command. crcenc: add flags avconv: use vsync 0 for AVFMT_NOTIMESTAMPS formats. tiffenc: add a private option for selecting compression algorithm md5enc: add flags ARM: remove needless .text/.align directives Conflicts: doc/APIchanges libavcodec/tiffenc.c libavutil/avutil.h libavutil/samplefmt.c libavutil/samplefmt.h tests/ref/fate/bethsoft-vid tests/ref/fate/cdgraphics tests/ref/fate/film-cvid-pcm-stereo-8bit tests/ref/fate/mpeg2-field-enc tests/ref/fate/nuv tests/ref/fate/tiertex-seq tests/ref/fate/tscc-32bit tests/ref/fate/vmnc-32bit Merged-by: Michael Niedermayer <michaelni@gmx.at>
