[Freeswitch-users] chromakey not replacing background properly

[Terry C]

Thanks for the reply, Mike. The png is in fact fully opaque. This is the
link to one of the png's I used that is all green that shows up as purple
in chromakey (https://1drv.ms/u/s!AjoGLBAOTKwok4sEsN_oFHpyx8QhCA). If there
is a sample png and/or mp4 that works that I can look at, I can compare and
see the differences.
