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
