RunCommandSuccess and RunCommandError were added to RipBot264.ini with version 1.24 and here is how I am using it to receive a notification on my phone whenever an encoding job completes
I have these 2 lines added to RipBot264.ini
RunCommandSuccess="C:\Scripts\RipbotSuccess.cmd" %JOB%
RunCommandError="C:\Scripts\RipbotError.cmd" %JOB%
In C:\Scripts\ I have curl.exe and the 2 batch files below
RipbotSuccess.cmd
c:\scripts\curl.exe -u {pushbullet token}:
https://api.pushbullet.com/v2/pushes -d type=note -d title="Ripbot264" -d body=%1+"Job Completed Succesfully"
RipbotError.cmd
c:\scripts\curl.exe -u {pushbullet token}:
https://api.pushbullet.com/v2/pushes -d type=note -d title="Ripbot264" -d body=%1+"Job Failed"
So with PushBullet installed on my phone I now get notifications whenever an encoding job completes
