Design

  1. Given a schedule file in XML format, and a subevent id
  2. This script parses it, and extract all timeslots for this subevent id
  3. For each timeslot, generate a Intro video, a QA video and an Exit video.
    1. slides/*-template.html contains html templates for these three slides
    2. This python script renders the templates into still images
      • Render once for each different video frame.
      • The only thing that can change is the clock image (or text). The clock changes every minute.
      • For video < 1min, we only need one frame (no clock updates)
      • For vidoe > 1min, we then need to render the template multiple times, one for each minute.
        • unimplemented
    3. Then the script generates slide videos from the images

Install

MacOS: bash ./setup-macos.h

Ubuntu: bash ./setup-linux.h

Run:

Generate splash videos:

  • For all events in all streams: ./gen-events.py
  • For one stream: ./gen-events.py --steam=SPLASHI
  • For one event: ./gen-events.py --stream=SPLASHI --event=5d1aeb28-75c6-4924-8e7a-5cbbe33cfacd

Generate fillers:

  • For all streams: ./gen-fillers.py
  • For one stream: ./gen-fillers.py --stream=SPLASHI
  • For one break: ./gen-fillers.py --stream=SPLASHI --time=16:30

            clock-16:30.mp4
            clock-16:35.mp4
            ...
            clock-17:05.mp4
            static-16:30.mp4
        <event-id>-A-intro.mp4
        <event-id>-A-qa.mp4
        <event-id>-A-outro.mp4
        <event-id>-B-intro.mp4
        <event-id>-B-qa.mp4
        <event-id>-B-outro.mp4

A means this video is used for the first round of 12-hours streaming.

B means the second round of streaming.

TODO

  • Keynotes get filtered out? (because no event_id present)
  • Styles
  • 12 Background images
  • Location name in top right corner
  • Display times for 13 different time zones
  • Top left corner: current stream
  • Better sponsor logos
  • Display auther names
  • Calculate time for qa-transition videos
  • Potential corner cases?
  • Output naming convention
  • Missing recorded_duration for some pre-recorded videos

Low Priority:

  • Fade-in animation for outro videos
  • High-resolution images
