It looks like your output file is H264 though? What are you seeing that
makes you think otherwise?  YUV420p is the pixel format that H264 is using
in your case. I also wasn't familiar with the -pix_fmt H264 option as I am
used to seeing YUV/RGB/XYZ type pixel formats in there, but I'm not
familiar with -f vl42 commands.

I see H264 here as your codec.
