<p class="MsoNormal">I'm looking for a non-GPL licenced x264 video encoder that I can use on the Raspberry Pi v3 (or 3 B+) hardware running some Linux variant. Ideally this encoder should support the NEON video acceleration block that is part of the Raspberry
Pi v3 or 3B+ SoC.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the following 19-Nov-2017 post, Nicolas Dufresne summarises use cases for some H.264 encoders:<o:p></o:p></p>
<p class="MsoNormal"><a href="https://lists.freedesktop.org/archives/gstreamer-devel/2017-November/066181.html">https://lists.freedesktop.org/archives/gstreamer-devel/2017-November/066181.html</a><o:p></o:p></p>
<p class="MsoNormal">The encoders Nicolas lists are: x264enc (GPL), vaapih264enc (Intel H/W), nvh264enc (nvidia H/W), openh264enc (Cisco free codec for PCs), omxh264enc (Raspberry Pi) & v4l2h264enc (with GStreamer 1.14+).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Of these, it would seem that omxh264enc & v4l2h264enc would be of interest.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">I see that the v4l2h264enc functionality was added to gst-plugins-good via Bug 728438<o:p></o:p></p>
<p class="MsoNormal"><a href="https://bugzilla.gnome.org/show_bug.cgi?id=728438">https://bugzilla.gnome.org/show_bug.cgi?id=728438</a> but I clearly don't understand how to gain access to it.<o:p></o:p></p>
<p class="MsoNormal">Is it possible to use this on a Raspberry Pi 3 or 3B+ and would it be NEON accelerated?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">Does someone know of a contact method that works?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please help!<o:p></o:p></p>
