Merge remote-tracking branch 'qatar/master'
* qatar/master: mpegvideo_enc: don't use deprecated avcodec_encode_video(). cmdutils: refactor -codecs option. avconv: make -shortest a per-output file option. lavc: add avcodec_descriptor_get_by_name(). lavc: add const to AVCodec* function parameters. swf(dec): replace CODEC_ID with AV_CODEC_ID dvenc: don't use deprecated AVCODEC_MAX_AUDIO_FRAME_SIZE rtmpdh: Do not generate the same private key every time when using libnettle rtp: remove ff_rtp_get_rtcp_file_handle(). rtsp.c: use ffurl_get_multi_file_handle() instead of ff_rtp_get_rtcp_file_handle() avio: add (ff)url_get_multi_file_handle() for getting more than one fd h264: vdpau: fix crash with unsupported colorspace amrwbdec: Decode the fr_quality bit properly Conflicts: Changelog cmdutils.c cmdutils_common_opts.h doc/ffmpeg.texi ffmpeg.c ffmpeg.h ffmpeg_opt.c libavcodec/h264.c libavcodec/options.c libavcodec/utils.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
