#

|
# Usage:
|
|
# ffmpeg -i input.mp4 -c:v copy (or reencode libx264) input.264
|
|
# python3 experiments/avd.py -i input.264 -a
|
|
#
|
|
# - Supports .264, .265, and .ivf formats.
|
|
# - Regarding the codec, it's whatever codec features are supported.
|
|
# Check avid for details.
|
|
# - Also ensure to change the sys.path.append above to the avid repo
|
