    A C program to repair corrupted video files that can sometimes be produced by
    DJI quadcopters.
    Version 2026-02-28
    
    Copyright (c) 2014-2026 Live Networks, Inc.  All rights reserved.

    Version history:
    - 2014-09-01: Initial version
    - 2014-09-21: When repairing 'type 2' files, we prompt the user to specify the video format
            that was used (because the SPS NAL unit - that we prepend to the repaired file -
	    differs for each video format).
    - 2014-10-04: We now automatically generate the name of the repaired file from the name of
            the original file (therefore, the user no longer specifies this on the command line).
	    Also, we can now handle certain (rare) files in which the
	    'ftyp','moov','mdat'(containing 'ftyp') sequence occurs more than once at the start.
    - 2014-10-11: When performing a 'type 2' repair, we now better handle the case where we see
            a 4-byte 'NAL size' of 0.  This anomalous situation can happen when a large chunk of
	    zero bytes appears in the file.  We now try to recover from this by scanning forward
	    until we see (what we hope to be) a 'NAL size' of 2, which would indicate
	    the resumption of sane data.
    - 2015-01-08: Handle anomalous 0xFFFFFFFF words that can appear at the start (or interior)
            of corrupted files.
    - 2015-01-24: We can now repair 'type 2' files that were recorded in 1080p/60 format.
            (The DJI Phantom 2 Vision+ doesn't yet record in this format, but some other cameras
	     can, and they can produce files that are corrupted in a similar way.)
	    We now also try to recover from encountering bad (far too large) NAL sizes when
	    repairing 'type 2' files, and unexpected garbage appearing at the beginning of files.
    - 2015-03-30: We now support two ('4k') video formats used by the Inspire 1:
            2160p/30 and 2160p/24, and updated the H.264 SPS data to work for 1080p/60 files
	    from the Inspire 1.  We also support a wider range of damaged files.
    - 2015-05-09: We now support an additional video format - 1080p/24 - used by the Inspire 1.
    - 2015-06-16: We now support an additional video format - 1080p/50 - used by the Inspire 1.
    - 2015-09-25: We now support two more video formats: 2160p/25 and 720p/25
    - 2015-11-03: We now support an additional video format - 1520p/30
    - 2015-11-27: Corrected(?) the SPS NAL unit prepended to each frame for the 2160p/25 format.

    - 2016-04-19: We now support an additional video format - 1520p/25
    - 2016-08-05: Made the checking for 0x00000002 a bit more robust: We now also check that the following bytes are sane
    - 2016-08-15: We now support an additional video format - 720p/48
    - 2016-12-08: We now support an additional video format - 1520p/24
    - 2017-02-10: We now support new-style movie files (e.g., produced by the Phantom 4 Pro)
    - 2017-02-11: We now support an additional video format - 2160(x4096)p/30 (for new-style)
    - 2017-03-13: We now use the term "4K" to refer only to 2160x4096 video.
                  We now support an additional video format - 1530p/24
    - 2017-03-20: We now support an additional video format - 1530p/30
    - 2017-04-02: We now allow 'mdat' atoms to have a (broken) atom size that's <8, because
      when we're checking for 'mdat' atoms, we don't use the atom size anyway.
    - 2017-04-08: We now support an additional video format - H.265 1080p/120
    - 2017-04-17: We now support an additional video format - H.265 1080p/25
    - 2017-04-24: We now support an additional video format - H.264 480p, from the XL FLIR camera
    - 2017-05-15: We now support an additional video format - H.264 2160(x3840)p/48
    - 2017-05-18: We now support an additional video format - H.264 2160(x4096)p/60
    - 2017-05-21: Improved the skipping over anomalous non-video data (e.g., in an Osmo file)
    - 2017-05-29: We now support an additional video format - H.264 2160(x3840)p/50
    - 2017-06-06: We now do a better job of searching for video data within a file. In particular,
                  we now detect H.264 SPS NAL units in addition to 2-byte NAL units.
    - 2017-06-14: We now support an additional video format - H.264 2160(x3840)p24 (type 2)
    - 2017-06-20: For clarity, added an output message when we start to repair 'type 4' files.
    - 2017-06-27: We now support an additional video format - H.264 1080p/120 (type 3)
    - 2017-06-28: Made the check for embedded H.264 SPS NAL units a bit more strict
    - 2017-06-29: Fixed a bug in 'type 4' file repair.
    - 2017-07-05: Loosened the check for embedded H.264 SPS NAL units to allow for Spark videos
                  (that have a shorter SPS length).
    - 2017-07-19: We now support 4 new video formats (used in the Mavic Pro):
                  1530p/25, 1080p/48, 720p/50, 720p/24
    - 2017-08-01: We now support an additional video format - H.264 1530p/30 (type 3)
    - 2017-08-25: We now support two new formats - 2160(x4096)p24 and 1080p24 (type 3)
    - 2017-08-29: The previous version's new format should have been 2160(x4096)p48, not p24
    - 2017-09-29: We now support an additional video format - H.264 2160(x3840)p60 (type 3)
    - 2017-10-10: We now support an additional video format - H.264 1530p/30 (type 3)
    - 2017-10-22: We now support an additional video format - H.264 1080p/25 (type 3)
    - 2017-11-04: We now support an additional video format - H.265 2160(x3840)p25 (type 3)
    - 2018-01-24: We now support an additional video format - H.264 2160(x4096)p25 (type 2)
    - 2018-01-27: Zenmuse apparently uses a different SPS/PPS for its (type 2) 1080p30 videos than
                  the Phantom did, so we added a new format for this.
    - 2018-02-21: We now support an additional video format - H.264 1080p/30 (type 3)
    - 2018-03-31: We can now repair more kinds of 'type 4' file (apparently from the Mavic Air)
    - 2018-04-22: We now support an additional video format - H.264 1520p/60 (type 2)
    - 2018-05-03: We now support an additional video format - H.264 2160(x4096)p25 (type 3)
    - 2018-07-11: We now support an additional video format - H.264 1080p60 (type 3)
    - 2018-08-01: If the size of the initial 'ftyp' atom is bad, just ignore it, rather than failing
    - 2018-08-17: We now support an additional video format - H.264 2160(x3840)p25 (type 3)
    - 2018-09-03: We can now repair at least some 'type 4' H.265 (HEVC) video files

    - 2019-06-09: The Osmo+ apparently uses a different SPS/PPS for its (type 3) 720p60 videos than
                  the Phantom did, so we added a new format for this.
    - 2019-08-20: We now support an additional video format - H.264 2160(x3840)p24 (type 3)
    - 2019-11-07: We now support an additional video format - H.264 720p (type 3)
    - 2019-11-19: The Mavic Mini changed the type 3 video format somewhat by adding a metadata track.
                  We now skip over blocks from this track (though print out the first block).
		  The H.264 1530p30 SPS and PPS values have been updated to conform to those now
		  used by the Mavic Mini.
    - 2019-12-28: Added support for the new SPS and PPS values used for 1080p30 by the Mavic Mini.
    - 2019-12-29: We now support an additional video format - H.264 1530p/25 (type 3)(Mavic Mini)
                  We also allow for variable-sized 'metadata' blocks in Mavic Mini videos.
    - 2020-01-07: We now support an additional video format - H.265 1080p60 (type 3)
    - 2020-01-08: Added support for the new SPS and PPS values used for 1080p60 by the Mavic Mini.

    - 2020-03-23a: We now support an additional video format - H.265 2160(x3840)p30 (type 3)
    - 2020-03-25: We now detect (and print the first occurrence of) an additional type of
                  metadata block.
    - 2020-04-14: The SPS for H.264 1530p/30 (type 3)(Mavic Mini) appears to have changed slightly.
    - 2020-05-05: We now support two additional video formats - H.264 1530p/24 (type 3)(Mavic Mini),
                  and H.264 1080p/24  (type 3)(Mavic Mini)
    - 2020-07-12: We now support an additional video format - H.265 1530p50 (type 3)
    - 2021-01-01: We now support an additional video format - H.265 2160(x3840)p30 (type 3)(DJI Mini 2)
    - 2021-01-24: We now support an additional video format - H.264 1520p60 (type 3)(DJI Mini 2)
    - 2021-06-21: Improved the checking for video in 'type 4' repairs, to (at least partially)
                  repair some Mavic FPV videos.
    - 2021-07-02: We now support videos from "DJI Mini 2" drones.  These are similar to
                  'type 3' videos, but lack a JPEG prefix.  We designate them as 'type 5'
		  videos, and allow the user to select only known "DJI Mini 2" formats.
                  We can now handle extended atom sizes for 'mdat' atoms (because we don't
		  use the size of 'mdat' atoms)
    - 2021-07-04: We support two more video formats - 3840x2160p24 and 1920x1080p48 -
                  for both 'type 5' (as in the previous version) and 'type 3' (i.e., with
		  JPEG previews).
		  To keep the number of (type 3) choices under control, we remove support
		  for H.265 120fps and H.264 120 fps.  If, however, someone needs these,
		  then let us know and we'll re-add them.
    - 2021-11-08: We now support an additional video format - H.264 720p24 (type 5)
    - 2021-12-02: We now handle 'isom' in addition to 'ftyp' at/near the start of the file.
    - 2022-01-13: We now handle a more general metadata block format (seen in the Mavic Mini SE)
    - 2022-03-28: Made the parsing/skipping of metadata blocks more robust.  Sometimes, the
                  'tail end' of the metadata blocks is non-printable-ASCII, which means that it
		  really doesn't exist.
    - 2022-04-17: Replaced the SPS data for (type 3) H.264 1530p, 48 fps so that it conforms
                  to video produced by newer DJI drones.
    - 2022-07-04: Fixed a bug in the allocation of the name for the output filename.
    - 2022-08-16: Improved the checking for video in 'type 4' repairs
    - 2022-09-05: Added a new format for 'type 5': H.264 1080p30 (Mavic Air)
    - 2023-01-14: Added a new format for 'type 5': H.264 1080p25 (Mavic Air)
    - 2023-04-19: Updated the format for 1080p30 'type 2' for (presumably) more modern devices
    - 2023-05-05: We can now identify and skip over some more types of Osmo audio data.
                  Added a new format for 'type 5': H.264 2160(x3840)p25.
    - 2023-06-03: We now support a new 'type 5' format for the DJI 03 Air: H.265 2016p60.
    - 2023-06-20: We now support a new 'type 5' format for the DJI 03 Air: H.265 2160p60.
    - 2023-11-24: Updated the 'type3or5Common' parsing to handle metadata tracks for DJI Air 3
    - 2024-01-22: We now support a new 'type 5' format: H.265 2160p30

    - 2024-05-04: We now support a new 'type 5' format: H.264 720p30
    - 2024-05-23: Added new special cases for 'type3or5Common' parsing
    - 2024-06-30: We now support a new 'type 5' format: H.265 1080p50
                  Added new special cases for 'type3or5Common' parsing
    - 2024-07-06: (internal release only) Updated support for H.265 1080p50
    - 2024-07-09: Converted 'djifix' URLs in diagnostic output from "http://" to "https://".
                  We now support a new 'type 5' format: H.264 1520p60
                  Added new special cases for 'type3or5Common' parsing
    - 2024-07-20: (internal release only) Additional tests for skipping 'track 2' audio data
    - 2024-09-04: Updated support for H.265 2016p60 (for the DJI O3 Air).
                  (Thanks to Stacey Abshire for providing example files to test this.)
    - 2024-09-06: Updated the H.265 SPS, PPS, and VPS NAL units for 2160x3840p30 (type 5)

                  H.265 (3840x)2160p60, so we now support both
    - 2026-02-26: We now support a new 'type 5' format: H.265 1080p25
