So what do I have to do now ?

My vlc player can read this stream and the info stream says it's H264.
My understanding is that I must check how to go through this with ffmpeg. Am I wrong ?

Because your data is MPEG Transport stream, the way in which you decode it is completely different.  (You don't deal with NAL units, or anything like that, because that's all hidden within the Transport Stream.)
