Ac4/atsc3.0 support

General Support / Questions
1

I just cross-compiled ffmpeg with ac4 support. I used the following projects.

and
GitHub - rdp/ffmpeg-windows-build-helpers: Helper script for cross compiling some media tools for windows, like customizable ffmpeg.exe (with or without non-free components, etc), and some other bonuses like mplayer, mp4box, mxf, etc. (current build has a slight typo, there is a hashtag on the wrong line)

the command I used in ubuntu 24.04 is:

./cross_compile_ffmpeg.sh --ffmpeg-git-checkout=https://github.com/elliotclee/FFmpeg.git --disable-nonfree=n

I am running initial conversions still and will post back when done

ffmpeg/ffprobe builds attached

I’m stuck on this, it keeps copying and then says audio error remux… After maybe a minute or two at the most it disappears from the job list, and then boom it finds the video again and does the continuous loop…
I found a temporary fix for myself…,.
Since it was recorded with emby using 3.0 tuner OTA antenna the TV channel is spitting out hevc and AC4…
I know that the problem is the AC4…
Since emby has a convert function…
Go to the video, select convert, replace existing file, select TS, video quality keep original, audio AAC…
After it is done with the file, I start MC buddy back running again, after that everything goes well.
If emby can convert the recording without any issues… MCE buddy should also be working just fine. It must be something that MCE buddy team can fix rather easily. The reason why I use MCE buddy for the conversion it’s because emby team is not wanting to give me full control over resolution versus bitrate.
It’s wanting to automatically adjust resolution based on bitrate… MCE buddy keeps the resolution and adjust the bit rate, and that’s exactly the way it should be… So overall MC buddy has a 90% better picture quality and compression of video using hevc :slight_smile:
