I really wish that they had chosen and already established audio format for use with ATSC3, rather than going with something new that is simply not supported by much of anything. I just don't feel that AC-4 is enough of an improvement to justify the change. Of course, with Dolby's lobbying dollars, they can make anything happen.(2022-04-19, 20:40)BeefJerky Wrote:I suspect that Atmos receivers would licensed to provide AC-4 support but it is up to the manufacturers to incorporate it. And then the question becomes can it be done by a firmware update or is different hardware required.(2022-04-19, 17:31)RKCRLR Wrote: I bumped my thread on the Nvidia forum. Nvidia support responded that the version of the MS12 stack used on SHIELD does not contain AC-4 support.
Now, I wonder if it's really true that Atmos receivers can decode AC-4 audio. If true, bitstream support for AC-4 in Kodi would solve the issue. If not, then we're really stuck until FFmpeg gets around to adding AC-4 support, which could take years based on what I'm seeing.

@ferrellsl Thanks for your post back in October. I'm a developer on the Cliff Watson EPG Program team. Our app is in the Windows Store and it will soon support HDHomerun ATSC 3.0 recordings. I've installed your VideoPlayer from GitHub and given it a spin. Thanks for creating it! It played our test clip (from the Charlotte DMA) well, so you can add that to the list. Do you still have the AC-4 Kodi version? I don't see how to send PMs in this forum, so I'm not sure how to contact you directly about this and I hope that you'll get a notification of my post.

I've completed a successful build of Kodi that supports ATSC3/HEVC/AC-4 audio. It is a 64-bit Windows build and has been tested on Windows 10 & 11 with the latest version of NextPVR. It successfully plays all the ATSC3 broadcasts in the Phoenix area but it hasn't been tested in any other locations. If anyone wants to download and test this build, contact me for a download link. The user assumes the responsibility for installing and configuring NextPVR correctly as well as configuring the NextPVR add-on within Kodi. I created this build because I'm cheap and didn't want to pay the folks over at SiliconDust just for the privilege of being able to schedule, record, and play back the new ATSC3 stations in my area. This build targets users of the new SiliconDust HDHomeRun tuners that support the ATSC3 standard so folks who don't own ATSC3 compatible tuners can just ignore this build.
