I would like to create a custom mixer layout using the instructions on the following page: https://docs.flashphoner.com/displa...Streammixer-Mixeroutputstreamlayoutmanagement The instructions said to run this line: javac -cp/usr/local/FlashphonerWebCallServer/lib/tbs-flashphoner.jar ./com/flashphoner/mixerlayout/mylayout.java But tbs-flashphoner.jar does not exist in my /usr/local/FlashphonerWebCallServer/lib folder. When I run the command, the following error appears: programLayout.java:3: error: package com.flashphoner.sdk.media does not exist 1) Should tbs-flashphoner.jar be in the lib folder? How can I get it there? 2) If I fix the tbs-flashphoner.jar issue, will it also fix the missing com.flashphoner.sdk.media package? Thank you!
