Callback function that is invoked when an asynchronous FFmpeg
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: * ReturnCode *returnCode = [session getReturnCode]; * break; * case SessionStateFailed: * NSString *failStackTrace = [session getFailStackTrace]; * break; * } ** * @param session session of the completed execution */ typedef void (*FFmpegSessionCompleteCallback)(const std::shared_ptr
