ATSC3 / AC-4 broadcasts failing

[brucearp 1]

We have 2 open ATSC3 channels we can watch, KPTM (Fox - Omaha) - 142.1 and KXVO - (Roar - Omaha) - 115.1.  When I try to watch either one through Emby using either a web browser or the Windows App, I get the error:

Playback Error
There was an error processing the request.  Please try again later.

Signal Strength and Quality all seem to be good watching the HDHomeRun Config GUI app. 

The channels do play fine using the HDHomeRun app on Windows.

 

The stream does work if I watch via RTP in VLC.

Log files attached.

From the transcoding log, it appears that FFMPEG is blowing up trying to transcode the AC-4 audio possibly?

 

Thanks

@brucearpDo you know if these channels use DRM encryption? Its very common among ATSC 3.0 Broadcasts, if so the channel cannot be viewed using the HDHomerun.

Nope, those 2 do not have DRM on them.  I can watch them in the HDHomeRun app, they just fail in Emby.  The stream will also play in VLC (minus audio, video only).
