Callback function that is invoked when an asynchronous FFprobe
session has ended.
*
Session has either SessionStateCompleted or SessionStateFailed state when * the callback is invoked. *
If it has SessionStateCompleted state, ReturnCode
should be checked to
* see the execution result.
*
If getState
returns SessionStateFailed then
* getFailStackTrace
should be used to get the failure reason.
*
* switch (session->getState()) { * case SessionStateCompleted: * auto returnCode = session->getReturnCode(); * break; * case SessionStateFailed: * auto failStackTrace = session->getFailStackTrace(); * break; * } ** * @param session session of the completed execution */ typedef std::function
