/**
* 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.
