I have a usb 3 webcam and I would like to simultaneously save a H264 video with audio and stream it over wifi, I tried different pipelines but nothing doing everything I want. The resolution needed is 3840x1088.

Hi,
You may try to launch RTSP server through test-launch. Please check
Jetson Nano FAQ
[Q: Is there any example of running RTSP streaming?]

Can try with videotestsrc and audiotestsrc plugins first:
Live streaming cam usb - #4 by DaneLLL
And then apply your audio/video sources.
