vf_pad calls ff_draw_init, which assumes BT.709 and TV range for its
YUV matricies. Since the filter only accepts RGB inputs for the color
argument, it needs to convert them to YUV for YUV input video, and it
should respect the tagged colormatrix when doing such a conversion, but
it does not. It can do this by calling ff_draw_init2, and this patch
causes the filter to re-init when the first frame is received, as that
is when that colormatrix tag becomes available.
If the filter is not initialized before the first frame, then an
assertion will fail in avfilter.c when it does sanity checks on
input/output dimensions, so the original initialization cannot be
skipped.
