Re: AC-4 Audio?

I REALLY hope SiliconDust will release a version of the HDHR where 1) All four tuners can receive ATSC3, and 2) it can transcode AC4 audio to AC3 in real time (personally I'd also take EAC3 a.k.a. Dolby Digital+, which seems to have better channel separation, but not all receivers can handle it). 1...

Re: AC-4 Audio?

I was looking to see if any progress has been made on adding AC-4 support to FFMPEG, because that is the key to getting AC-4 audio to work in most if not all of the video player software out there. Virtually everything relies on FFMPEG and so far there has been little progress aside from richardpl's...

Re: AC-4 Audio?

The one thing I would really like to see is a static build of richardpl's ffmpeg for LINUX, similar to the ones at https://johnvansickle.com/ffmpeg/ for the master branch. Not everyone uses Windows, and at the same time not everyone that uses Linux (particularly as a home theatre system) is a progr...

Re: AC-4 Audio?

I don't know if this will help you at all, but it looks somewhat similar to what you are trying to do. It is decoding the audio in real time from a satellite TV channel from a big old C-band satellite dish, that sends six channels of audio (5.1 format) in three discrete 2-channel streams. You shoul...

Re: AC-4 Audio?

As an interim transcoding measure, I'm playing with turning the AC-4 audio into AC-3 (without decoding the video) using richardpl's FFmpeg-ac4 and passing it on to another device. Not something I've done before, so I have yet to work out the output format, but it should go something like this: ffmp...
