> 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.

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.

I have successfully built Kodi v18.9 against the AC-4 branch of ffmpeg.
ATSC3.0 captures work seemingly flawlessly with audio. I cannot verify if
it's 5.1 and the channels are correct but on my computer with stereo
headphones the audio sounds great.
Tuning live ATSC3.0 is really buggy using the HDHomerun plugins but it
will occasionally play and when it does there is audio. I don't think
this has anything to do with ffmpeg but rather the plugins themselves.
