+ * GstJPEG2000Sampling:
+ * Sampling values from RF 5371 for JPEG 2000 over RTP : https://datatracker.ietf.org/doc/rfc5371/C
+ * Note: sampling extensions that are not listed in the RFC are signified by an _EXT at the end of the enum
+ *
+ * @GST_JPEG2000_SAMPLING_NONE: no sampling
+ * @GST_JPEG2000_SAMPLING_RGB: standard Red, Green, Blue color space.
+ * @GST_JPEG2000_SAMPLING_BGR: standard Blue, Green, Red color space.
+ * @GST_JPEG2000_SAMPLING_RGBA: standard Red, Green, Blue, Alpha color space.
+ * @GST_JPEG2000_SAMPLING_BGRA: standard Blue, Green, Red, Alpha color space.
+ * @GST_JPEG2000_SAMPLING_YBR444: standard YCbCr color space; no subsampling.
+ * @GST_JPEG2000_SAMPLING_YBR422: standard YCbCr color space; Cb and Cr are subsampled horizontally by 1/2.
+ * @GST_JPEG2000_SAMPLING_YBR420: standard YCbCr color space; Cb and Cr are subsampled horizontally and vertically by 1/2.
+ * @GST_JPEG2000_SAMPLING_YBR411: standard YCbCr color space; Cb and Cr are subsampled vertically by 1/4 (Since: 1.20).
+ * @GST_JPEG2000_SAMPLING_YBR410: standard YCbCr color space; Cb and Cr are subsampled vertically by 1/4 alternating the Cb and Cr component.
+ * @GST_JPEG2000_SAMPLING_GRAYSCALE: basically, a single component image of just multilevels of grey.
+ * @GST_JPEG2000_SAMPLING_YBRA4444_EXT: standard YCbCr color space, alpha channel, no subsampling,
