these are the relevant patches:
*motion.h*:
in struct context : insert
?? int overlay_pass;
*in motion.c:*
motion_init() after pthread_setspecific insert:
????? cnt->overlay_pass = 0;
motion_overlay() at top of func: insert
? ? ? ++cnt->overlay_pass;
?????? MOTION_LOG(DBG, TYPE_ALL, NO_ERRNO, "overlay_pass:%d",
cnt->overlay_pass);
process_image_ring() after struct image data line insert:
????? MOTION_LOG(DBG, TYPE_ALL, NO_ERRNO, "ringout:%d ringin:%d",?
cnt->imgs.image_ring_out, cnt->imgs.image_ring_in);
-----
I don't see anything wrong per say in the code with the added debug ...
except that debug confirms the
code is still being called after an individual camera is restarted while
the web streaming img data to my firefox
browser sees nearly all the time after the restart a static frame even
after multiple page refreshes with an occasional new static picture,
its not until I do an all cameras restart that it works correctly.
Further snapshot are still occurring for the said camera ... appears
somehow the web streaming data is hosed ... further looking at the
snapshots after the restart that occur every 2 seconds I do see they are
happening
with text over lay stuff with time that is getting incremented ... so
the issue looks to be the web streaming portion is some how hosed with a
individual camera restart ... also note I do set stream_port 8081 in
main conf (motion.conf) file which not sure if that may be different
than others are using and hint where to search for the problem.

Okay, I got it working so that I can make Motion write the captured video in
pretty much any codec I want. I had to rebuild ffmpeg from scratch on my
system. I had an *extremely* old version (2.X.X).
Once I rebuilt the newer ffmpeg (4.2.1), I then had to remove Motion and then
rebuild it using --with-ffmpeg, reinstall it and voila...Motion writes my
files as whatever I choose - mkv, mp4, avi, hvec, etc.
I'm now trying out the example given in the Motion help file using mkv:libx265
in the hopes that that will give me the clearest files and at the same time
the smallest.
As for how Slackware does dev files...I don't know how to explain it, only
that if one builds a Slackware package from source, it somehow automatically
has the dev part *and* the usable part mixed together in the end txz file that
gets installed.
Thanks again though for all the help and the pointers that got me going in the
right direction to get this figured out.
JB
