  1. I use command: ./h264enc -utype 0 -org 1111.yuv -numl 3 -numtl 1 -frin 30 -frout 0 30 -frout 1 30 -frout 2 30 -sw 720 -sh 1280 -dw 0 180 -dh 0 320 -dw 1 360 -dh 1 640 -dw 2 720 -dh 2 1280 -rc -1 -lqp 0 24 -lqp 1 24 -lqp 2 24 -iper 0 -bf OUTPUT.264 -mfile 1
  2. Three files are then generated，OUTPUT_layer0.264，OUTPUT_layer1.264， OUTPUT_layer2.264
  3. then I use command: ../h264dec OUTPUT_layer0.264 1.yuv. 1.yuv can be created.
  4. but I use command:ffmpeg -i OUTPUT_layer0.264 1.yuv, There seems to be an error:

Because FFMpeg don't support subset_seq_parameter_set.

I have the same problem, could you tell me how to solve it?

you can first filter the outputted 264 file and drop what you do not want (like subset sps, etc) then do following ffmpeg decoding.
