Video to texture via libtheoraplayer

[Niosop]

Well, it took me two days and the final result was like 12 lines of code, so I feel pretty dumb. But, I learned a lot and found the AWESOME libtheoraplayer library, so I'm happy. Doing this brought up some issues, like not having the ability to load vorbis sound data from an ogg theora+vorbis file, and the lack of features to help with syncing sound to video. But all in all it is actually REALLY easy to do and performs very well. You can see a short demo here:

 

Performance is excellent. Due to libtheoraplayer being multithreaded, I actually get almost no impact to framerate because of the decoding process, although this only helps on a multicore system with a free core to do the decoding. Minimum I saw was 80FPS for that scene when not using FRAPS. Just rendering the video to a surface alone was giving me about 250FPS.

 

I'm thinking about writing a shader to do the Y'CbCr->RGB conversion, but with it being on a separate thread it might actually hurt performance on multicore machines. Will try it out sometime and let you guys know. The video playing is Elephant's Dream, the house is by GIMPY73.

This is amazing. You even used the average pixel color to control the light color.

[Paul Thomas]

That is awesome man. Great job.

[Laurens]

I'm stunned, that is truly amazing!

 

Great job

[Marleys Ghost]

Now that's impressive and two days well spent, nice job Niosop

[Pixel Perfect]

Very nice demo, well done! That guy seriously needs to stop watching television though and seek medical attention

flawless victory

[AggrorJorn]

awesome! It looks realy good. Perhaps you can add some fluctuation to the light? This adds more realism to it. Take for example the code from the firepit.lua.

[Canardia]

Wow cool! I love how the brightness of the TV screen works as a light too, but a colored like Josh said would add a huge realism and should be quite easy to do too.

[Niosop]

Actually it is colored. The video is crappy quality but there's a point light right in front of the screen. Every loop it takes the average color of the screen and changes the point light to that color.

[Rick]

Very cool. Now how do we do it

[Niosop]

Will post code today

[Jordan]

Looks great. And the light is a nice touch, seems very realistic.

that friggin rocks...nice work, Niosop!

It would be cool if we actually had some source code to look at...
