I haven’t developed a plug-in in a while and my knowledge is out of date. When I used theta4j, I built two minimal examples. I’m not sure if they still work.
GitHub - codetricity/theta4j-minimal-example: Minimal example for RICOH THETA plug-in using theta4j library by Shiro. - there are 5 branches to this to show a single point per branch
GitHub - codetricity/theta4j-fisheye: dual-fisheye example for RICOH THETA using theta4j - concept to show stitching control. Unfortunately, does not appear to reduce the time taken per shot.
There are a number of examples for MotionJPEG.
Note that there is another example use of pushing the MotionJPEG from the plug-in to an Arduino. This is likely not a relevant, but cool.
BTW, if this is a commercial project with potential sales potential for RICOH, please send a note to @jcasman as we can try and get more help from RICOH. This forum receives sponsorship from RICOH and we like to report back on activities. You can either send a direct message through the forum or send an email.
No problem if this is a research or hobby project. We can continue to support your project in this community forum.
