What is MPV Player? How to configure custom parameters?

## Decoding/Rendering Settings##

# Video output driver, Windows can choose gpu/gpu-next/direct3d etc., gpu is the most mature and stable, gpu-next is experimental, direct3d is only used when compatible with old system hardware
vo=gpu
# Set hardware decoding API, auto/auto-copy/no correspond to automatic/automatic-memory copy/soft decode
hwdec=auto
# Rendering API, can choose auto/d3d11/opengl/vulkan
gpu-api=auto
# Try using hard decoding formats (default h264, vc1, hevc, vp8, vp9, av1; all is a special value indicating all formats)
# hwdec-codecs=all
# gpu-api=d3d11 when (win default api) multi-GPU platforms specify the used GPU, GPU name reference device manager. This option recognizes the first string, if it's not the same GPU, no need to input full name. If using Vulkan, it is vulkan-device=
# d3d11-adapter=AMD
# d3d11-adapter=Intel
# d3d11-adapter=NVIDIA
# d3d11va zero-copy mode, can reduce GPU 3D engine usage
# d3d11va-zero-copy=yes

## Cache Settings##

## Playback Status Recording##

# Remember playback status when exiting (including pause, volume, playback speed, position etc.)
save-position-on-quit
# Playback status save location
# watch-later-directory=D:\Cache\watch_later
# Do not record whether paused (except pause similarly can write fullscreen, mute, speed, ontop etc. parameters)
watch-later-options-remove=pause
# Record playback status while ignoring file path (for backup/sharing, but affects same-named files distinction)

# Set default window size and position (example is 1280x720, bottom-left of screen)
# geometry=1280x720+100%+100%
# Drag-and-drop file behavior setting (no/auto/replace/append). no disable drag-and-drop, auto automatically select according to platform, replace replace current file and play, append add dragged files to playlist. Default is drag-and-drop replace, hold shift drag-and-drop append

# OSD information position, font size, border size (left/center/right, top/center/buttom)
osd-align-x=left
osd-align-y=top
osd-font-size=22
osd-border-size=2
# Set the duration of OSD text information (milliseconds)
