/*
* CHANGES 01.2020
* - ffprobe support changes
* - (optindex < argc) validation in parse_options() method updated with (optindex >= argc) check
*
* CHANGES 12.2019
* - Concurrent execution support
* - log_callback_report method re-added to fix -report option issues
*
* CHANGES 08.2018
* --------------------------------------------------------
* - fftools_ prefix added to the file name and parent header
*
* CHANGES 07.2018
* --------------------------------------------------------
* - Unused headers removed
* - Parentheses placed around assignments in conditions to prevent -Wparentheses warning
* - exit_program updated with longjmp, disabling exit
* - longjmp_value added to store exit code
* - (optindex < argc) validation added before accessing argv[optindex] inside split_commandline()
* and parse_options()
* - All av_log_set_callback invocations updated to set ffmpegkit_log_callback_function from FFmpegKitConfig.m. Unused
* log_callback_help and log_callback_help methods removed
* - (idx + 1 < argc) validation added in parse_loglevel()
