# This script accepts an 8-bit, YUV420, pre-encoded h264 file and will send the rotated, encoded h.264 output to /tmp/xil_rotate_<N>.mp4 at a rate of 8Mbps.
# Direction flag enumeration:
# direction = 0 -> Rotate by 90 degrees counterclockwise and vertically flip (default)
# direction = 1 -> Rotate by 90 degrees clockwise
# direction = 2 -> Rotate by 90 degrees counterclockwise
# direction = 3 -> Rotate by 90 degrees clockwise and vertically flip
# Passthrough flag enumeration:
# none
# Always apply transposition.
#
# portrait
# Preserve portrait geometry (when height >= width).
#
# landscape
# Preserve landscape geometry (when width >= height).
