Hello,

How you are playing the yuv file?
The h264 codec is using NV12 format.
I would recommend you to check this guide also:

HI：
Use a yuv picture viewer

I also use the following order will be reduced to y2v h264, in the play, but still the same effect
gst-launch-1.0 -v filesrc location=1.yuv ! videoparse width=352 height=288 format=nv12 ! ducatih264enc ! queue ! filesink location=test.h264
gst-launch-1.0 -v filesrc location=test.h264 ! queue ! h264parse ! ducatih264dec ! waylandsinnk

Please use playbin to decode the encoded file.

gst-launch-1.0 playbin uri=file:///<path_to_file> video-sink=kmssink
or

gst-launch-1.0 playbin uri=file:///<path_to_file> video-sink=waylandsink


where <path_to_file> is the full path to the file.

You could try also:
gst-launch-1.0  filesrc location=output.264  ! typefind ! h264parse ! ducatih264decvpe   ! kmssink
