Use ffmpeg and mp4box to prepare DASH-AVC/264 v1.0 VoD
See my DASH-IF presentation from October, 2014:
https://s3.amazonaws.com/misc.meltymedia/dash-if-reveal/index.html#/
1. encode multiple bitrates with keyframe alignment:
ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
-g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4
My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.

JJY.js: Web Audio API based JJY transmitter

JJY.js: JJY time signal emulation/transmission library

Usage

  1. Make sure that the watch/clock is configured to receive JJY 40 KHz signal (for most Casio Waveceptor/G-Shock watches, the easiest way is to enter the engineer menu by pressing Mode+Light+Receive and select J 40 reception mode, for all other watches you need to set the home city to Tokyo)
  2. Make sure your device clock is in sync before running the emulator and the headphone volume is turned to the maximum.
  3. From the page, run:

Converts images in a directory to a comic/manga EPUB3 ebook. Can be used to convert extracted CBZ/CBR to EPUB3.

images2epub.py

Converts a directory of images into a modern EPUB3 ebook. Use a tool to extract CBZ/CBR/CBT files and then run this program to generate a nice fixed-layout EPUB ebook of it. You can optionally set the reading direction to right-to-left (e.g. for manga). For Kobo ereaders, use the file extension .kepub.epub to get the modern reader and correct reading direction.

Usage

Install dependencies with pip install imagesize lxml
