gst/ffmpegcolorspace/gstffmpegcodecmap.c: Replace __VA_ARGS__ caps creation macros with varargs functions. looks nice...
Original commit message from CVS: Patch by: Sebastien Moutte <sebastien moutte net> * gst/ffmpegcolorspace/gstffmpegcodecmap.c: (gst_ff_vid_caps_new), (gst_ff_aud_caps_new), (gst_ffmpeg_pixfmt_to_caps), (gst_ffmpeg_smpfmt_to_caps): Replace __VA_ARGS__ caps creation macros with varargs functions. Makes things compile on MSVC (#320765), looks nicer, and we can tell the compiler to check for the NULL terminator.
