* qatar/master: doxygen: Consistently use '@' instead of '\' for Doxygen markup. Use av_printf_format to check the usage of printf style functions Add av_printf_format, for marking printf style format strings and their parameters ARM: enable thumb for Cortex-M* CPUs nsvdec: Propagate error values instead of returning 0 in nsv_read_header(). build: remove SRC_PATH_BARE variable build: move basic rules and variables to main Makefile build: move special targets to end of main Makefile lavdev: improve feedback in case of invalid frame rate/size vfwcap: prefer "framerate_q" over "fps" in vfw_read_header() v4l2: prefer "framerate_q" over "fps" in v4l2_set_parameters() fbdev: prefer "framerate_q" over "fps" in device context bktr: prefer "framerate" over "fps" for grab_read_header() ALSA: implement channel layout for playback. alsa: support unsigned variants of already supported signed formats. alsa: add support for more formats. ARM: allow building in Thumb2 mode Conflicts: common.mak doc/APIchanges libavcodec/vdpau.h libavdevice/alsa-audio-common.c libavdevice/fbdev.c libavdevice/libdc1394.c libavutil/avutil.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
