Tweaking the boot animation
 OS 10.1.x
 Technical notes and rebuilding the rpm
In 10.1.x and later, this has changed from being 26 frames simply copied to /usr/share/boot-anim or ~/.bootanim to being the starting frame and a file deltas that describes the difference between the frames.
The simplest thing to do is to to download the source package from , replace the files frame00.png to frame25.png and then run ./configure and make the normal way. Then copy the the frame00.565 from images and the file deltas from the delta folder to /usr/share/bootanim . Reboot and you should see your new boot animation.
Do not use the -z flag.
You can convert the 565 files back to a png using:
ffmpeg -vcodec rawvideo -f rawvideo -pix_fmt rgb565 -s 1200x900 -i frame00.565 -f image2 -vcodec png frame00.png
 OS 8.2.x and earlier
The boot animation code lives in the
bootanim rpm, and it uses the rhgb-client hooks in the initscripts. There are 26 frames in the boot animation, fixed by the number of steps in the initscripts.
The frames live in /usr/share/boot-anim/frame00.565 to /usr/share/boot-anim/frame25.565. They are in the raw framebuffer format. You can convert a PNG with the command:
pngtopnm frame00.png | ./ppmto565.py -z -o frame00.565
using the ppmto565.py script and the
pngtopnm tool in the netpbm-progs package:
# yum install netpbm-progs
If you are targetting a release prior to 8.2, you should omit the '-z' option. The resulting files are raw bitmap data and look large, but they compress well onto jffs2 if the images are simple.
The bootanim code lives in the act-gui package in git on dev; talk to cscott if you want changes pulled upstream.
