Demo:Sprite Animation
This demo shows how you can use this library to do sprite animation.
This is particularly useful as you can have many high resolution frames per second with very little RAM cost compared to regular sprite animation.

Sprite Animation
The character has 20 sprites for each direction, 250x300 pixels, which is 160 frames at about 300KB per image (RGBA data).
Which totals to 45 MB of RAM required for it's storage. If you have to store it in the Display card's RAM, it's even more because textures have to have power of two dimensions.
By using this library, you have 8 video clips loaded into RAM, each 500x300 in size (double the width because you have to pack the alpha channel as well)
The clips altogether are 1.7MB in size, let's say each videoclip object has 2 precached frames, which is 6.8MB and another 512x512 texture that goes into the Display Card's RAM.
The benefit is that you can have a lot of frames per second at very little cost to the filesize.
The downside is that you have to use the CPU to decode the video. This demo uses about 10% CPU on a single-core system. However, since most modern systems have at least two CPU cores, the job is given to the other core while the first one is fully at your disposal.
