* master: (403 commits) Initial caf muxer. Support decoding of amr_nb and gsm in caf. Fix decoding of msrle samples with 1bpp. udp: remove resource.h inclusion, it breaks mingw compilation. ffmpeg: Allow seting and cycling through debug modes. Fix FSF address copy paste error in some license headers. Add an aac sample which uses LTP to fate-aac. ffmpeg: Help for interactive keys. UDP: dont use thread_t as truth value. swscale: fix compile on mingw32 [PATCH] Update pixdesc_be fate refs after adding 9/10bit YUV420P formats. arm: properly mark external symbol call ffmpeg: Interactivity support. Try pressing +-hs. swscale: 10l forgot git add this change from ronald. AVFrame: only set parameters from AVCodecContext in decode_video*() when no frame reordering is used. avcodec_default_get_buffer: init picture parameters. swscale: properly inline bits/endianness in yuv2yuvX16inC(). swscale: fix clipping of 9/10bit YUV420P. Add av_clip_uintp2() function Support more QT 1bpp rawvideo files. ...
