Comment (by TanMan):

 I had tried -maxrate, but it didn't help. Since you recommended it, I
 tried it again:

 ffmpeg -i input -c:v hevc_amf -maxrate 2000k output

 The error message is indeed gone, but the maxrate is not being honored.
 This is why I thought it wasn't right, and I didn't included this in my
 original posting. This is the encoding status being reported while
 encoding:

 bitrate=20136.7kbits/s speed=14.2x

 So it's fast, and there's no error, but it's still creating a huge file.
