/**
 * JPEG 2000 Profiles (stored in rsiz/capabilities field in code stream header)
 * See Table A.10 from 15444-1 (updated in various AMDs)
 *
 * For broadcast profiles, the GST_JPEG2000_PARSE_PROFILE_BC_XXXX profile value must be combined with the target
 * main level (3-0 LSBs, with value between 0 and 11).
 * Example:
 * capabilities  GST_JPEG2000_PARSE_PROFILE_BC_MULTI | 0x0005 (in this case, main level equals 5)
 *
 * For IMF profiles, the GST_JPEG2000_PARSE_PROFILE_IMF_XXXX profile value must be combined with the target main level
 * (3-0 LSBs, with value between 0 and 11), and target sub level (7-4 LSBs, with value between 0 and 9).
 * Example:
 * capabilities  GST_JPEG2000_PARSE_PROFILE_IMF_2K | 0x0040 | 0x0005 (in this case, main level equals 5 and sub level equals 4)
 *
 *
 * Broadcast main level (15444-1 AMD4,AMD8)
 *
 * Note: Mbit/s == 10^6 bits/s;  Msamples/s == 10^6 samples/s
 *
 * Level 0: no max rate
 * Level 1:	200 Mbits/s, 65  Msamples/s
 * Level 2:	200 Mbits/s, 130 Msamples/s
 * Level 3:	200 Mbits/s, 195 Msamples/s
 * Level 4:	400 Mbits/s, 260 Msamples/s
 * Level 5:	800Mbits/s,  520 Msamples/s
 * Level >= 6: 2^(Level-6) * 1600 Mbits/s, 2^(Level-6) * 1200 Msamples/s
 *
 * Broadcast tiling
 *
 * Either single-tile or multi-tile. Multi-tile only permits
 * 1 or 4 tiles per frame, where multiple tiles have identical
 * sizes, and are configured in either 2x2 or 1x4 layout.
