Bitstream file name:
SUBPIC_E_HUAWEI_1.bit

Explanation of bitstream features:
sub-pictures of varying sizes. using the example configuration file subpicture_4_slice_2_tiles_4_subpic.cfg in cfg/partitioning,
# assuming an 832x480 input sequence with CTU size = 128x128, and split to 4 rectangular slices, each slice include one tile.
# example 2 tiles, 4 subpictures (and each subpicture is a slice) in a 832x480 picture:
#----------
#|    |   |
#|    |   |
#|----|---|
#|    |   |
#|    |   |
#----------
#     |
#     v
# vertically divided into 2 tile, each tile includes two subpictures/slices


Profile, tier, and level for the bitstream: 
Main 10 profile, Main tier, Level 3.0


Max picture width and height, and any additional picture width and height values used (i.e., for reference picture resample or scalability):
SourceWidth=832
SourceHeight=480

Picture rate:
FrameRate = 30 

The bitstream can be decoded using VVC software, at Merge request https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/-/merge_requests/1509
will be soon merged in master branch, with commit: 0aefaba567ef86258432a3681a5243537ca332da
VTM-8.0 is not used because tile/slice implementation has a bug.
