 https://github.com/richardpl/FFmpeg/tree/ac4 using Linux Mint 20.1.  It
 built successfully and I was able to play the atsc3.ts samples with AC-4
 audio using ffplay.

 code.

 Let us know if you're successful.  I'd really like to have a PVR that
 records and plays ATSC3.0 streams without using a bunch of scripts and
 hacks.  Over at the NextPVR forums there's a guy who has written some
 python scripts that use the binaries from this tree to transcode the
 ATSC3.0/AC4 audio stream into AC3 on-the-fly but I'm hoping for a cleaner
 solution.

 For now, I can still record my ATSC3.0 channels using NextPVR and use the
 binaries from this tree for playback of those ATSC3.0 recordings without
 transcoding, and of course all the 4K channels in the Phoenix area are
 mirrored in 1080p/ATSC1.0 channels. I'm quite pleased with richardpl's
 progress.  I was expecting things to move much slower than they have, or
 not at all.  At least now I have a poor-man's PVR using scripts for
 playback.  Having AC4 integrated natively into VLC, Kodi, or NextPVR would
 be very welcome from my standpoint.
