Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

• -r 24 - output frame rate
• -pattern_type glob -i '*.JPG' - all JPG files in the current directory
• -i DSC_%04d.JPG - e.g. DSC_0397.JPG
• -s hd1080 - 1920x1080 resolution

Slower, better quality

# Combined all static libaries in the current directory into a single static library
# It is hardcoded to use the i386, armv7, and armv7s architectures; this can easily be changed via the 'archs' variable at the top
# The script takes a single argument, which is the name of the final, combined library to be created.
