# camera_frame_drop_counts_per_stream
#
# Total number of dropped frames per stream type.  Typically, the system decides
# to skip a delivered frame in following cases:
#   1. FrameAvailableInfo contains an erroneous status,
#   2. Delivered frame has a duplicated identifier,
#   3. Delivered frame does not have a timestamp,
#   4. Or, too many frames are currently in use.
