VLC 3.0.4 transcode error: Unsupported pixel size 0 (chroma CVPN)

I have 12 *.mov files that I recorded this week with my iPhone. The codec is hvec (H.265). They all play fine in VLC 3.0.4 on my MacBook. I would like to upload them to Facebook, so I'm converting them to H.264 that Facebook supports. 2 of the 12 failed with the same error when I tried to convert them:

Disable hardware decoding, and try again.
