To all:
I did some more work on the bash script file:
You will need to determine your build directory and root directory for
this script and NOT use the values herein.
The input from the command line is %bash make-GOES-fulldisk-vid.sh parm1
parm2
If you don't enter parm1 or parm2 the default is GOES16 for 576 frames
(2 days)
If you enter parm1 (which is the satellite) it can be 16, or 18, or 19
(when it becomes fully released by NASA)
If you enter some other value for parm1, it assumes GOES16 and frame
count = parm1
If you enter in parm1 and parm2, this specifies the satellite and frame
count
If you enter in parm1 = satellite and parm2 = all, then ALL possible
jpgs are yanked from the NASA website = 2869 in all
Please be aware that the all option will take over 2 hours to run.
The program is smart enough to grab all possible jpgs, when selecting a
large number of frames, since new frames arrive after the start of the
program. I found 3 passes are sufficient.
I found that the 5424x5424 pixels size and 10848x10848 pixels size for
the jpegs are too big to assemble into a full video and keep it a
reasonable size.
The standard frame default is 1808x1808 pixels for the fulldisk videos.
You will need "identify", "wget" and "ffmpeg" commands installed and
operational on your linux system as prerequisites, the other commands
are usually standard on any linux.
Having said all these caveats, here is the bash script file
