I am trying to make a script that automatically creates a mp4 video for Android boot animations. Any help would be appreciated. I am attempting to accomplish this on Ubuntu using ffmpeg.

Here is an example of a boot animation: https://github.com/CyanogenMod/android_vendor_cm/blob/cm-11.0/prebuilt/common/bootanimation/1080.zip?raw=true

Video of the animation: https://www.youtube.com/watch?v=jSbo14yUfRI

The boot animation usually has a couple of folders with images. The animation will be played image by image. The animation also has a file named "desc.txt" which describes how the animation should be played.

Example of desc.txt:
---------------------------
1080 608 25
p 1 8 part0
p 0 17 part1
---------------------------

Explanation of desc.txt:
----
1080   = width of the images
608    = height of the images
25     = frames per second
----
p      = play
1      = play the files in this animation only once (0=forever|1=one time)
8      = pause 8 seconds before playing the animation
part0  = the folder inside the zip that contains the images to play
----
p      = play
0      = loop over the animation until the phone completes booting up
17     = pause 17 seconds before playing this part of the animation
part1  = the folder inside the zip that contains the images to play

Goal: Create a script that automatically unzips the bootanimation, orders the images and outputs a video according to the desc.txt.
