# Show the audio + video codecs that PJSIP actually registered in the
# currently-installed sipsimple build. Useful to verify that optional codecs
# (G.729, opus, AMR-WB, etc.) made it into the compiled _core.so.
#
# Usage:
#     ./06-show-codecs.sh
#
# Exits 0 if the engine started and the codec list was printed; non-zero if
# something went wrong (import error, engine never came up, etc.).

# can't shadow the venv install via CWD-on-sys.path. We want to verify what
# the venv actually has, not whatever happens to be next to setup.py.
