Hardfloat (HF) Demo

Features

• Plays .gmv.gz video via gmplay with separate audio via SoX.
• Simple script launcher for quick demos in KTerm.
• Works when audio and video files match; bundled demo media is not synchronized.

Requirements

• Jailbroken Kindle running hardfloat firmware.
• KTerm terminal installed.

Download & Install (HF)

1. Download video-audio-all.zip (Google Drive).
2. Unzip on your computer or Kindle.
3. Place the videos folder in your Kindle root (/mnt/us).
4. Place the vidoe-audio folder (typo intentional) into /mnt/us/extensions/.

How to Run (HF)

cd /mnt/us/extensions/vidoe-audio/
chmod +x playgmvmp3.sh
./playgmvmp3.sh

• The bundled HF demo uses gmplay’s sample video with a separate audio track (not synchronized).
• To create a synced demo, put matching .gmv.gz and .wav files in /mnt/us/videos/ with consistent names, and edit the script if necessary.

Softfloat (SF) Demo

Requirements

• Jailbroken Kindle with softfloat firmware.
• KUAL (Kindle Unified Application Launcher) installed.

Download & Install (SF)

1. Download bad_apple.tar.xz.
2. Unzip on your computer or Kindle.
3. Place the bad_apple folder into /mnt/us/extensions/.

How to Run (SF)

Open KUAL and launch the demo directly from the menu. It plays the included video using gmplay and SoX when supported.
