[FFmpeg-user] How to generate h.264 raw data

[Deron]

Is it possible to output just raw h.264 data? Better yet, both AnnexB 
and AVCC? Or is there a simple muxer that I can use that won't be so 
hard to look through to see the h.264?

I tried

ffmpeg -i "test.avi" -c:v libx264 -bsf h264_mp4toannexb -f h264 -an -y 
"test.h264"

But the data it generated did not look correct, as far as I understand 
it (which is what I am trying to learn, so my understanding is very 
limited!).

Thanks,
Deron
