Merge remote-tracking branch 'qatar/master'
* qatar/master: ppc: drop unused function dct_quantize_altivec() mpegaudiodec: Do not discard mp_decode_frame() return value. matroska: do not set invalid default duration if frame rate is zero mkv: use av_reduce instead of av_d2q for framerate estimation mkv: report average framerate as minimal as well avcodec_string: Favor AVCodecContext.codec over the default codec. cook: Make constants passed to AV_BE2NE32C() unsigned to avoid signed overflow. Conflicts: libavcodec/cook.c libavcodec/ppc/mpegvideo_altivec.c libavcodec/utils.c libavformat/matroskadec.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
