Structure of Boot animation
If you extract the contents of the bootanimation.zip file to your computer, you will see
Desc.txt file
Part 0 folder(contain png or jpeg images in order form)

It depends on device screen resolution 6 is the frame rate in fps (frames per second) number of images to display per second.
The second and line p represent part of animation and end with part0 or part1 and 0 represent how many times this part
will loop before switching to the next part (if exist) and here 0 number represent it will run infinite till boot complete and
1 represents it will run the single time and hang in the last image till boot. Send number 0 is for pause and it represent in frame
A pause of 5 for example, would mean pausing for the time it takes 5 frames to play and since the frame rate is 6
frames per second.
