29 * This file is the modified version of ffprobe.c file living in ffmpeg source code under the fftools folder. We
30 * manually update it each time we depend on a new ffmpeg version. Below you can see the list of changes applied
31 * by us to develop mobile-ffmpeg and later ffmpeg-kit libraries.
32 *
33 * ffmpeg-kit changes by ARTHENICA LTD
34 *
35 * 07.2023
36 * --------------------------------------------------------
37 * - FFmpeg 6.0 changes migrated
38 * - fftools header names updated
39 *
40 * mobile-ffmpeg / ffmpeg-kit changes by Taner Sener
41 *
42 * 09.2022
43 * --------------------------------------------------------
44 * - implemented writer_printf_printf using av_vlog
45 * - printf statements replaced with av_log
46 * - volatile dropped from thread local variables
47 * - sections cleaned before starting a new execution
48 *
49 * 01.2020
50 * --------------------------------------------------------
51 * - ffprobe support (volatile added to critical variables, options updated as ffprobe_options, printf
52 * statements replaced with av_log, dropped static variables in methods, show_help_default renamed as
53 * show_help_default_ffprobe, implemented exit_program with longjmp, OptionDef defines combined)
54 * - concurrent execution support ("__thread" specifier added to variables used by multiple threads,
55 * static keyword removed from methods called by both ffmpeg and ffprobe)
56 * - main() function renamed as ffprobe_execute()
