23 * CHANGES 01.2020
24 * - ffprobe support changes
25 * - (optindex < argc) validation in parse_options() method updated with (optindex >= argc) check
26 *
27 * CHANGES 12.2019
28 * - Concurrent execution support
29 * - log_callback_report method re-added to fix -report option issues
30 *
31 * CHANGES 08.2018
32 * --------------------------------------------------------
33 * - fftools_ prefix added to the file name and parent header
34 *
35 * CHANGES 07.2018
36 * --------------------------------------------------------
37 * - Unused headers removed
38 * - Parentheses placed around assignments in conditions to prevent -Wparentheses warning
39 * - exit_program updated with longjmp, disabling exit
40 * - longjmp_value added to store exit code
41 * - (optindex < argc) validation added before accessing argv[optindex] inside split_commandline()
42 * and parse_options()
43 * - All av_log_set_callback invocations updated to set ffmpegkit_log_callback_function from FFmpegKitConfig.m. Unused
44 * log_callback_help and log_callback_help methods removed
45 * - (idx + 1 < argc) validation added in parse_loglevel()
