Video + Audio Playback (Experimental)

Experimental demo that pairs gmplay video with SoX audio on Kindle.
Not a polished media player—intended for tinkering and proof-of-concept only.
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.
