I hope there will be. I'm not aware of any helpers and I had to do it manually.

However you can check how gst-dsp constructs the header here:
https://github.com/felipec/gst-dsp/blob/master/tidsp/td_h264enc.c#L189

I was doing the same a few weeks ago. Constructed the structure, copied it to a GstBuffer
and handed it over to mp4mux and it was happy so I can say that no wrapping was needed.

Cheers,
