h264, parsing NAL units

[ash5]

Hi,

I am writing a H264 analyzer to show how the video is encoded and may be try to dump a picture frame from the encoded stream.

My question is, how do I parse the NAL units to get this information, I have looked into the FFMPEG's code to do this but I was lost.
I also posted it on SO on this.

Can someone help me?

1. Read the H.264 spec, where the process is clearly described.

2. Look at the JM reference decoder source code.
