Merge remote-tracking branch 'qatar/master'
* qatar/master: (21 commits) fate: allow testing with libavfilter disabled x86: XOP/FMA4 CPU detection support ws_snd: misc cosmetic clean-ups ws_snd: remove the 2-bit ADPCM table and just subtract 2 instead. ws_snd: use memcpy() and memset() instead of loops ws_snd: use samples pointer for loop termination instead of a separate iterator variable. ws_snd: make sure number of channels is 1 ws_snd: add some checks to prevent buffer overread or overwrite. ws_snd: decode to AV_SAMPLE_FMT_U8 instead of S16. flacdec: fix buffer size checking in get_metadata_size() rtp: Simplify ff_rtp_get_payload_type rtpenc: Add a payload type private option rtp: Correct ff_rtp_get_payload_type documentation avconv: replace all fprintf() by av_log(). avconv: change av_log verbosity from ERROR to FATAL for fatal errors. cmdutils: replace fprintf() by av_log() avtools: parse loglevel before all the other options. oggdec: add support for Xiph's CELT codec sol: return error if av_get_packet() fails. cosmetics: reindent and pretty-print ... Conflicts: avconv.c cmdutils.c libavcodec/avcodec.h libavcodec/version.h libavformat/oggparsecelt.c libavformat/utils.c libavutil/avutil.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
