   My video player of choice is vlc. Issuing the ldd command above against its   
   binary yields no results, but I know it will play back the 264 video. OTOH,   
   running the above command against mpv yields results that would indicate that   
   it does support 265 but it won't play the video back correctly, either.

   I think you have that last bit re:bloat backwards. The same size video file   
   that will hold nearly 20 minutes when H.265 is enabled will only hold 3 minutes   
   of video if H.264 mode is used. That is why I am trying to use it. H.264   
   fills up a 64GB SD card in less than 3 hours. It takes well over 5 hours to   
   fill it when using 265.    
      
   Those times are when shooting video at 1080p and 90fps.
