-Software version 201810270 (not yet released) introduces the capability to add audio to H264 encoded video.  This is achieved using a new version of avc2ts (written by F5OEO).  This version has some limitations, but achieves much better picture quality from the Pi Camera at low SRs than the previous version.

-This mode works well from 250 KS 7/8 FEC up to 4 MS.  For lower symbol rates, the Audio should be switched off, which will switch in the older avc2ts encoder without audio.

 Note that on the Waveshare 3.5 inch screen, the viewfinder does not fill the screen.  This is intended behaviour.  Also, on the 7 inch screen, the viewfinder is off-centre.
