Not sure about libx264rgb. Is packed RGB encoding supported on high bit depth
x264 builds?

+
+x264 supports 8- to 10-bit color spaces. The exact bit depth is controlled at
+x264's configure time. FFmpeg only supports one bit depth in one particular
+build. In other words, it is not possible to build one FFmpeg with multiple
+versions of x264 with different bit depths.
+
+The supported pixel formats for each bit depth is listed below.
