# .INFO

# This will try to use your gpu AMD/INTEL to transcode video into X265
|
|
# The will also remux existing video to a streaming optimized mp4 container
|
|
# If it can remux your video it will extract subtitles and delete the mkv container
|
|
# .FYI
|
|
# QSV and libfdk_aac support requires compiling your own ffmpeg
