it's true that the real value is 30000/1001 = 29.97002997
changing it in my local tree now, would commit it later today
thanks for spoting this
actually, it is defined here :
gst-plugins/ext/libfame/gstlibfame.c: "framerate = (double) { 23.976024,
24.0, 25.0, 29.970030, 30.0, "
gst-plugins/ext/dv/gstdvdec.c:#define NTSC_FRAMERATE 29.997
gst-plugins/gst/y4m/gsty4mencode.c: 29.970, 30.000, /* NTSC */
other numbers that are rounded differently :
23.976023999999999 = i don't know (25000/10001 gives 24,975024975)
59.940060000000003 = NTSC * 2 = 60000/1001
