   To add further value to this thread about interoperating with the iPad HEVC   
   files that are made in "live photo" shots, while Icaros solved the   
   thumbnail problem, IrfanView 32-bit could not play MOV files from an iPad.   
      
   BACKGROUND:   
   Since my phone is broken, I used the iPad to snap photos where live photo   
   has an advantage that it can capture flickering multiplexed LED segments.   
      
   However, when stepping through the files copied from the iPad to the   
   Windows PC, Irfanview would no play the MOV files using default settings.   
      
   Irfanview 4.70 32-bit   
    Options > Property/Settings > Video/Sound   
    (_) Use external player (IV_Player Plugin (old) required)   
    (o) Use internal video/sound player (recommended)   
        [x] Use DirectShow for playing (use Pause/Arrow keys as controls)   
        [_] Loop   
        [_] Hide playbar in full screen mode (use ESC to exit)   
        Video window size:   
          (_) Half   
          (o) Normal   
          (_) Double   
    [x] Play MP3/OGG/RA files in the main window (using DirectShow option)   
    [x] Try to play Flash video (FLV) files in the main window   
    Apple Quick Time (Quick Time Plugin required - but NOT recommded)   
    [x] Use Quick Time for MOV/3GP/MP4/M4A/FLI/FLC files (if Quick Time   
   installed)   
    [_] Use Quick Time for QTIF, Mac PICT files   
      
   Error shown:   
       "Decode error!   
        Can't load Plugin: QUICKTIME.DLL   
        The Plugin is disabled."   
      
   This means IrfanView was trying to use the OLD QuickTime plugin,   
   which no longer exists on modern Windows and cannot decode HEVC.   
      
   iPad/iPhone MOV files are usually:   
    Video: HEVC (H.265) or H.264   
    Audio: AAC   
   IrfanView can only play these using DirectShow + modern codecs.   
      
   ROOT CAUSE:   
   IrfanView was *forcing* the QuickTime plugin for MOV playback.   
   Because QUICKTIME.DLL was missing, playback failed immediately.   
   IrfanView never attempted to use DirectShow or LAV Filters.   
      
   FIX:   
   1. In IrfanView 4.70 32-bit:   
      a. Options -> Properties/Settings -> Video/Sound   
      b. UNCHECK:   
          [ ] Use QuickTime for MOV/3GP/MP4/M4A/FLI/FLC files   
      c. CHECK:   
          [x] Use internal video/sound player   
          [x] Use DirectShow for playing   
      d. Restart IrfanView.   
      
   2. Install a modern DirectShow codec pack (K-Lite Full works).   
      This provides:   
       a. LAV Video (HEVC/H.264 decoding)   
       b. LAV Audio (AAC)   
       c. LAV Splitter (MOV/MP4 container)   
      
   3. Verify in Codec Tweak Tool:   
       DirectShow Filters -> LAV Video -> Formats   
        Ensure:   
         [x] H.264   
         [x] HEVC   
         [x] MPEG-4   
       (The hardware-acceleration tab is irrelevant if HEVC is grayed out.)   
      
   After doing that just now, when I step through a Windows folder with iPad   
   MOV & JPEG files, IrfanView now uses DirectShow + LAV Filters instead of   
   QuickTime such that MOV files from iOS now play correctly.   
      
   The result is we now have the interoperability of both thumbnails for the   
   Apple MOV files & Irfanview can play MOV files along with the JPG images.   
      
   NB: Icaros only affects MOV thumbnails; it does NOT affect playback.   
   This added-value post is about MOV playback inside of Irfanview.   
      
   Without losing the privacy inherent in getting the codec from Microsoft.

   Privacy is a feature you build yourself into everything you touch and use.
