LoveVideo - LÖVE module for playing video

[undef]

Would it be possible to stream video and draw other stuff on the it?
That way I could make complex backgrounds which would be to expensive to calculate in realtime.
Like fractals.

If I understand you correctly, this should be no problem. If you look at the API, you can do whatever you want;

Code: Select all

LoveVideo = require "LoveVideo.lovevideo"
cool_joe = LoveVideo.newVideo('cool_joe')
function love.graphics.draw()
  cool_joe:draw()
  drawFractal() -- Draw a crazy fractal on top of your video!
end

[undef]

I was rather thinking of the fractal as the video:
(Because I can not animate fractals in realtime)

Code: Select all

fractal = love.video.newVideo( "crazyFractal" )
function love.graphics.draw()
  love.video.draw( fractal )
  drawStuff() -- Draw other, probably still quite crazy stuff on top of it
end

But I'm glad this should work.

I don't really know how this works, but since a video is only images with audio, is it also somehow possible to stream from a .gif file?
Otherwise I could just repack it as video, but that would seem strange...

Because I made some nice gifs with LÖVE (from pngs), that are to costly to render in realtime.

Your use case is rather out of scope.

You could just use imagemagick's convert to export them to PNG's and then just display them at whatever FPS you want.

But if you *REALLY* want to use LoveVideo, you can.

I used imagemagick's convert to extract the gif to a bunch of PNG's (119 of them). With the assumption that it should be 24fps, that means there needs to be an empty audio file of 119/24 seconds, which is about 4.983 seconds. I used audacity to make that.

Then I configured the info.lua as follows;

Code: Select all

local info = {}

info.image_format = "png"
info.fps = 24
info.frame = {
  width = 500,
  height = 500,
  rows = 1,
  columns = 1
}

return info

Attached is a working thing-a-ma-bob.

Oh I'm terribly sorry.
It was quite a long time ago I wrote that code, and somehow I though it didn't run in realtime when I just looped through the pngs, but apperently it does...
I don't know why I thought it didn't, maybe it was still LÖVE 0.8, or there was some other reason it didn't run smoothly then.

Sorry again for the effort I've caused you.


Anyway, thanks a lot!
And great work on the module, keep it up

Code: Select all

cool_joe = love.video.newVideo('cool_joe')
function love.graphics.draw()
  love.video.draw( cool_joe )
  drawFractal() -- Draw a crazy fractal on top of your video!
end

You should update the code to make it use something other than love's namespace – it's bad practice in general to do that, plus if/when a real love.video module gets added to LÖVE then any code that overwrites love.video for its own purposes (such as the above snippet) will cause the real love.video to break horribly.

Maybe it's a hint that he wants you to implement his library, slime.

Cool stuff though, I wish I had the brain capacity to use magic and threads like that.

Causing a real love.video to break when this one is used is an odd way to encourage me.

I don't know, you do love breaking things.

My video conversion went bad when I sent it in youtube, btw the second video playing is 1280x720
