LoveVideo - LÖVE module for playing video

[josefnpat]

LoveVideo

Taking a lot of inspiration from this thread, I refactored and documented the mjpeg library into a module.

There is also a handy dandy bash script that takes most of the hassle out of making the target videos.

Much löve to all you devs who made this possible.

Please direct bugs, patches and feature requests here: https://github.com/josefnpat/LoveVideo/issues

Features:

• Supports PNG/JPG and now DDS!
• Full OOP
• Love like API for easy implementation;

  Code: Select all

  LoveVideo = require "LoveVideo.lovevideo"
  
  bunny = LoveVideo.newVideo("big_buck_bunny")
  
  function love.draw()
    bunny:draw(0,0,
      love.graphics.getWidth()/bunny:getWidth(), -- x scale
      love.graphics.getHeight()/bunny:getHeight() -- y scale
    )
  end
  
  function love.update(dt)
    bunny:update(dt)
  end

• Inline LDOC documentation for easy usage and generation.
• Convert tool for generating the target video (love-video) from any video type supported by avconv
• Sample Generation tool for generating a sample with the previously mentioned convert tool.
• Back-end threading to attain awesome framerate performance (like love-mjpeg!)
• Aggressive caching to reduce overhead by about 100%.

any new formats or new features?

Amazing

What file formats does this support?

What file formats does this support?

TL;DR; everything, but in all reality, it's fake.

LoveVideo can support any video that `avconv`, `ffmpeg` or any other frame grabber can extract from a video. The file "format" is a directory containing;

• jpg/png images (%d.[jpg|png]),
• audio data (audio.ogg) and
• metadata containing playback information (info.lua).

You can see examples here: http://50.116.63.25/public/lovevideo/samples/

In all technicality, mjpeg did not support mjpeg's. It does the same thing as this library does.

I imagine one could introduce something like luaplayer, but then you have a solution that isn't pure lua, and you get shafted when you want portability.

There is mjpeg-player-for-LOVE-engine ... might be able to incorporate some of that in, but from personal experience there are some bugs with this for android.

Nice.

What about using dds (dxt)?

Nice.

What about using dds (dxt)?

Assuming that imagemagick can handle the conversion (or you have the frames in that format already)

you should be able to;

• Update the output format of the format script; https://github.com/josefnpat/LoveVideo/ ... ert.sh#L21
• Add the image extension to the assert list; https://github.com/josefnpat/LoveVideo/ ... eo.lua#L60

I don't see why it shouldn't work then!

I thought, maybe dss/dxt offers better compression.

10:40 <bertbas> josefnpat: it also loads faster, btw
10:40 <bertbas> which may be interesting for your purposes

I've got a patch right now that makes it happen, but I'm getting segfaults (as is bartbes), so I won't push it into the mainline yet;

I'm doing something along these lines to repro;

Code: Select all

git clone git@github.com:josefnpat/LoveVideo.git && cd LoveVideo
wget http://pastebin.com/raw.php?i=YBfMFhMT -O dds.patch
patch -p1 < dds.patch
./tools/gen_sample.sh
love .

Ok, hate to double-post so soon, but I have added DDS/RX1 compression!

Quite a fantastic performance increase!
