I've started work on a module that simplifies video playback using Brucey's AVbin module and any help is greatly appreciated!
It's open source and available for download over at https://bitbucket.org/Hezkore/teasyavbin

The idea is to simply load a video file and draw it like an image.
If you build using threads it will use its own thread to decode the video and audio.

Here's a simple example of how it works:

Local MyVideo:TEasyAVbin = LoadVideo("video.avi")
While Not KeyDown(KEY_ESCAPE)
    MyVideo.Update
    MyVideo.Draw(0, 0) 
    Flip
Wend

At the moment using VSync causes some stuttering, especially without threads and that's one thing I'd like some help with.

Works fine without vsynch, also some stuttering with vsynch on. But it works fine too if vsync=-1.
I don't know what Brucey's module does, nor yours, but all in all I would say that it's extremly nice to have a video play possibility. Thanks for that module !

IIRC The avbin one taps into the windows media player playuback system, and will play any video type for which windows has a CODEC installed. Makes it very flexible, but the downside is that you are dependend on whatever codec the user does or doesn't have on their system.

There's already a few other modules that can deal with video without those outside dependencies, but are limited to specific encoding formats (and therefors probably more suitable for playing video as part of a game, since you can control the video format in that situation:

pantsonhead wrote an Ogg Vorbis and an MPEG-2 video playback module (video only), and Brucey created an Ogg Vorbis module that can play video + synched sound
