This will provide you with an hardware accelerated H264 encoder.

Of these, it would seem that omxh264enc & v4l2h264enc would be of interest. I've not been able to get the video4linux2 plugin (from gst-plugins-good) to provide more than the three elements: v4l2src, v4l2sink & v4l2radio even when I compile v4l-utils v1.14.2 and gstreamer v1.14.1 from source. I see that the v4l2h264enc functionality was added to gst-plugins-good via Bug 728438 <a href="https://bugzilla.gnome.org/show_bug.cgi?id=728438" rel="noreferrer noreferrer" target="_blank">https://bugzilla.gnome.org/show_bug.cgi?id=728438</a> but I clearly don't understand how to gain access to it. Is it possible to use this on a Raspberry Pi 3 or 3B+ and would it be NEON accelerated? I have tried an earlier version of omxh264enc but it’s didn’t like the stream from my camera and I’m yet to try again with GStreamer release 1.14.1. I'm aware of the very good x264enc element which is nominally GPL licenced but is supposed to be available under alternate licencing if you contact them but all three attempts I have made to do so have gone unanswered. Does someone know of a contact method that works?
