• The Kindle needs to be jailbroken.
• Terimnal access on Kindle (Kterm or SSH)
  • Generate a directory to store all temporary files on Kindle, using /mnt/us/demo/ for example in this tutorial.

Slice Video Frames

i=INPUT.mp4; w=1236; h=1648;
# Adjust resolution accordingly:
# - Kindle Paperwhite (11th gen.): 1236x1648
# - Kindle Paperwhite (12th gen.): 1264×1680
# - Kindle Colorsoft: 1264×1680

mkdir -p ./frames && ffmpeg -i "$i" \
-vf "transpose=1,\
	scale=$w:$h:force_original_aspect_ratio=decrease,\
	pad=$w:$h:(ow-iw)/2:(oh-ih)/2,\
	format=gray" \
-r 5 ./frames/frames_%04d.png

Copy all PNG images (the frames folder) to Kindle, put under /mnt/us/demo/.

Tips

Expedite the process of cleaning filler files on macOS

• Disable Spotlight on the Kindle

  sudo mdutil -i off /Volumes/Kindle
  

• Expedite the cleaning process (should finish around 2 minutes)

  rm -rf /Volumes/Kindle/.active_content_sandbox
  

Otherwise it may take over an hour to delete the recursive folders (around 5000)

Equivalent/Mapping Paths

Folder /mnt/us/ on Kindle (internally) is the same as /Volumes/Kindle/ (externally) on macOS

Introduction

A brief guide to setting up a stealthy, NAT-transversing SSH tunnel using VLESS + REALITY on Debian. This configuration allows you to securely access a private machine (Client) through a public VPS (Server) while masking traffic as a standard TLS handshake to a legitimate website.

1. Pre-requisites

Have xray-core set up and running with a basic VLESS + REALITY configuration Check the previous article. This guide focuses on the additional steps to enable SSH tunneling through the established VLESS + REALITY connection.

Introduction

Bilibili provides Danmaku in an XML format that mpv cannot natively render. Furthermore, Bilibili’s AI subtitles often use non-standard language tags (like ai-zh), which can lead to “null” tracks or rendering errors in older mpv kernels (like the one used in IINA).

Thankfully, yt-dlp allows us to extract and download these Danmaku and AI subtitles; danmaku2ass(deveoped by @m13253) provides a brilliant solution to convert XML files to ASS subtitles.

Introduction

A brief guide to set up a VLESS with Reality server on a Debian-based system using binary releases.

VLESS is a stateless proxy protocol designed for high performance and low overhead. REALITY is a security layer that eliminates TLS fingerprints by “borrowing” the identity of other websites. Together, they provide superior stealth against Deep Packet Inspection (DPI).

• Protocol (VLESS): Handles user authentication (UUID) and data routing. It does not encrypt data on its own.
