Why can't I tune to HEVC channels from my HD Home Run FLEX 4K

I saw this post from 2 years ago: No ATSC 3 channels with Plex and HDHomerun?

Why is this still not something Plex supports? Are there any plugin or workarounds?

Looking at other threads, it sound like it is an issue with ffmpeg decoding Dolby AC4.

The FCC is taking public comments on over the air standards. More info on: https://www.youtube.com/watch?v=wEf2Jot7ZQM

What are the specific issues I can site if I make a comment to the FCC?

We can only speculate. But an educated guess would be that Dolby and Plex are thus far unable to agree on a mutually-acceptable license for the AC-4 audio codec. Plex is pretty meticulous about ensuring they’ve properly licensed all of the proprietary technology they use.

Another educated guess is that there is a great deal of uncertainly surrounding the long-term adoption and viability of ATSC 3.0, in general. One of the primary concerns for wide adoption is the use of DRM (one of the points in the video you linked, actually). Plex never supported DRM on cable-based products from HDHR, so they’re unlikely to do so on OTA tuners. With widespread adoption of DRM on ATSC 3.0 (3 out of 5 of my local stations employ it), it’s going to be a real challenge.

Indeed there is. Check out this project:

Since you’re on Linux, you could pretty easily stand up this container. It emulates an HDHR tuner; when you tune through it, it will convert the AC-4 audio stream from an ATSC 3.0 source to (E)AC-3 and pass it along to Plex.

Something to note: The HDHR adds 100 to every ATSC 3.0 channel. So, if 13.1 in your area is available on both ATSC 1.0 and ATSC 3.0, you’ll have both 13.1 and 113.1. However, in Plex, you can only use any guide data source once. So you’ll have to deselect 13.1 and select 113.1, using 13.1’s guide data.
