guess in this case you (accidently?) selected rendering option making new
file at each label (3rd radiobutton out of four) instead of rendering whole
file/ in-out region....

usually yes, you can try to build it differently

./configure --help | grep thirdparty
  --with-thirdparty use thirdparty build (yes)

but this usually will have chance to work only if system ffmpeg at same
version as internal copy... Also, internal ffmpeg patched quite heavily...

see above, there is dependency in thirdparty/Makefile so x264/x265 built
first, and then ffmpeg built  pointed at those libs. Still, I need to
double-check for possible missing static switch.. On termux x265 built with
only 8 bit depth for system, so I need patch and CinGg renders h265/h264,
so I guess this  part works here...
