Re: MythTV HDHR5-4K integration

Thank you very much for the helpful reply!! I'll pass this on to the Dev I'm working with. HEVC works fine but as you indicated, AC-4 needs work. I've been attempting to patch the MythTV internal FFMPEG with the AC-4 fork and have gotten it to compile clean but still don't get AC-4 audio playing. I ...

MythTV HDHR5-4K integration

Hi there, The HDHR5-4K has gotten some attention of the MythTV devs and I'm helping to test various patches against the Master branch. In MythTV we support all HDHomerun boxes using the libhdhomerun API. We'd like to support the HDHR5-4K so we can receive the programs in the ATSC3.0 streams. Is ther...

Updated hdhomerun_config software for linux?

Is there a timeline to get an updated hdhomerun_config (and hdhomerun_config_gui) for linux? It seems we are behind our Win10 brethren when it comes to the software. I'm starting to help out with ATSC3.0 support on MythTV and would like to make sure I have everything I need to troubleshoot.

Thanks!

Re: ATSC 3.0: Portland - Jan 2021

Just a quick note for those following here: Nextstar was able to make some changes to the PLP structure so they are now running two PLPs. PLP 0 is now "robust" and only has KATU on it (around 2 Mbps) while PLP 1 is "fixed" with both KOIN and KRCW (around 20 Mbps total). .... Observing KATU over the...

Re: List of Hardware and Software that Supports Dolby AC-4

Are you using the HDHomerun app, or just as a UPnP/DNLA media device? Btw, I believe the CX and other 2020 LG OLEDs should have ATSC 3.0 tuners builtin to the TV already. So that is another avenue to tune to the channels if you're so inclined. The GX has the ATSC 3.0 tuner but not the CX or below. ...

Re: List of Hardware and Software that Supports Dolby AC-4

Here's another data point... I picked up a LG OLED CX TV this weekend. The WebOS sees the HDHR on my network as a multimedia device. I can stream TV from it and it happily plays the PDX ATSC 3.0 streams with audio and video. Pretty stable as well...

Is this with the modified source to have it recognize the AC-4 codec?
Yes
Fantastic! Great job! Do you have a list of the files you edited?

Re: AC-4 Audio?

Well, I'm gonna give the VLC build a rest. I've spent the better part of a week building and testing for Win64 with limited success. Adding the ffmpeg AC-4 branch to the build did not enable AC-4 audio playback as I had hoped so there have to be more adjustments that need to be made that are outsid...

Re: AC-4 Audio?

VLC is a dumpster fire in terms of building. Problems range from regression errors to broken scripts. I spent a day and a half trying to build it against the AC-4 branch and whenever I fixed one problem it would expose 3 more so I'm giving up for now. :lol: I've been trying as well but I can't figu...

Re: AC-4 Audio?

I was able to compile Kodi 18.9 against the ffmpeg AC-4 branch. Playing ATSC 3.0 stream captures from the PDX market worked well and audio seemed find. I cannot confirm if it was correct channel 5.1 because this was being done on my desktop rather than HTPC (headphone only on my desktop). Live TV wa...

Re: AC-4 Audio?

That branch is against the main trunk. I compiled a 4.3.x version and Kodi now plays audio for ATSC 3.0 Dallas, TX stations (H.265 + AC-4). I expect it will take a few months for slower distributions to get ffmpeg 4.4 / 5.0 that will carry this support, but we'll be there much sooner than I guessed...

Re: ATSC 3.0: Portland - Jan 2021

This has been a great discussion.... Thanks much for the insight!

Also explains why the ATSC3 is running with such low bandwidth here. In many cases it looks much worse than it's ATSC 1.0 counterpart...

Re: AC-4 Audio?

There are many software systems (Kodi, plex, VLC, handbrake, MCEBuddy...) that use FFmpeg, so the key to getting the ball rolling on various systems is to get AC-4 implemented in FFmpeg. There is an FFmpeg enhancement ticket that is currently marked as PRIORITY: WISH. if enough people logon to the ...
