"Unknown picture type encountered" when trying to use libx265 encoding with ffmpeg

[Warren Menzer]

Getting an "Unknown picture type encountered" error when running the following command with ffmpeg using the latest x265 code:

ffmpeg -i spec/files/hevc.mp4 -y -c:v libx265 -tag:v hvc1 -preset fast -f mp4 -r 30 -c:a aac -ar 48000 -ab 192k -ac 2 -crf 18 -pix_fmt yuv420p /tmp/out.mp4

This is occurring with the latest code (e94ed0c) and does not occur with the version prior to changes committed over the past couple of days (dd594f5).
