Hi videoh

That are great news.
Could you keep in mind your project should run on Linux and Windows and we need all what eac3to can do plus a bit more.
In my case I have often seamless branching BDs and eac3to has some bugs for e-ac3 streams.
Skip identical frames works almost for all cases but not 100%.

Thanks in advance, great!

Would next week be possible? I've decided to spend my end-of-year holidays early and I'm eager to unpack my X-mas presents.

Be realistic.
As good as he is, you can't expect videoh to produce all the eac3to features within the snap of a fingers.
It will be allready very great if there is a simple demuxer wich demux properly streams where eac3to fails.

Just successfully did a first full demux from Cars 2 UHD using DGDemux. I have to clean up some stuff, remove the licensing, and make a manual. Maybe by Thanksgiving, or even next week!

I will start a new thread for further status reports, as it doesn't belong here.

EDIT: New thread is here:

Found a problem with eac3to v3.34. It freezes while attempting to analyze a full ABC network feed mux. It gets to 96% and halts.

A sample tsreader capture of the mux is here (53,879,018 bytes).

MediaInfo reads it just fine.

MediaInfo does not analyze the whole file, only the file parts where it assumes to find the headers with the attributes describing the content (usually in the beginning of a file, sometimes in the end as well). It will most probably skip parts with possible broadcast data errors.

Maybe there are some problem at end of mux (96%), MediaInfo never read all the stream, only the headers.

ffmpeg info say:

I tried opening the file with tsmuxer (2.6.15) and it complained about pieces of it and ignored a couple of video streams and audio streams. So, I did another capture of 500 MB and tsmuxer didn't like it either. So I read the new file into VideoReDoPro and extracted each of the 6 programs (1 video stream and 5 audio streams). Not one error was reported. I remuxed the 6 TS files into a M2TS file via tsmuxer and eac3to liked it.

I have no idea what is wrong with a complete mux capture that causes eac3to and tsmuxer to not like it. If I just capture one of the program streams, eac3to doesn't have an issue with it.

Thanks for the pointers.

As a side note, I normally do not capture the ABC network feed. I'm only doing it lately because of the Jeopardy! special programming. And because ABC switched over from H.264 to H.265, I was also testing out my ZShell script extract a single stream and extract three of the audio streams to convert the MPA to DD5.1 AC3. When eac3to hung I thought that the new 3.34 version had issues. Turns out that the ABC network feed has something in it that eac3to and tsmuxer do not like, when captured as a whole.

Hi @MrVideo,

It's been a few years since I've played around with transport streams that contain multiple TV channels. But I seem to remember that Mosu's MKVToolNix did quite a good job at identifying all the separate streams...

I know what all of the streams are. I don't use eac3to to identify the streams, but to extract one of the program's video and audio streams in order to create 6 separate wave files from the MPA stereo audio streams so that I can use ffmpeg to create an AC3 5.1 file that I'll then tsmuxer into a new TS file. I have a Zshell script that runs all of the pieces. If eac3to can't find all of the streams, it means that I have to use VideoReDo to pull what I want into a new stream that will then be used to create the AC3 file. That said, it means that I should only capture the program that I need, which is what I am doing as I write this.

There is always a way around an issue.

I have a UHD disc with different audio streams with different delays. The THD+AC3 (Atmos) stream has a -5ms delay and I was told earlier in this thread that eac3to cannot apply a delay to those streams. This results in the file name being appended with a "DELAY -5ms". The other audio streams show a -17ms delay but the file names are not appended. Looking at the log, it shows the -17ms streams have had a adjustment applied to the stream by eac3to. It also shows that +15ms of the delay could not be applied to the same streams.

Is the timing of these audio streams correct when eac3to corrects them even when showing it couldn't correct it completely?

eac3to v3.34

The only way to correct delay, without recode, is add/delete full audio frames to extracted streams.

- eac3to can't do it to TrueHD streams.
- Over AC3 streams can add/delete frames of 32 ms, then over -17 ms delete 1 frame and the output need a + 15 ms of furter delay to be applied in the next container.
- BTW delays lower than a video frame duration, here 41.7 ms, can be ignored safely because can't be detected.
- If you insist to extract a stream with 0 ms of delay you need recode the AC3 (not recommended) with something like:

8: stdout.w64 -17ms | ffmpeg -i - -c:a ac3 -b:a 640k -center_mixlev 0.707 %_8spa.ac3

I have a UHD disc that outputs the following:

eac3to v3.34
command line: "C:\eac3to.exe" "C:\XXXXX" 1) -log="C:\log.txt"
------------------------------------------------------------------------------
M2TS, 1 video track, 5 audio tracks, 5 subtitle tracks, 2:13:12, 11.987p
1: Chapters, 16 chapters
2: h265/HEVC, unknown parameters
3: DTS Master Audio, English, 7.1 channels, 24 bits, 48kHz
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
4: AC3, Spanish, 5.1 channels, 640kbps, 48kHz
5: AC3, French, 5.1 channels, 640kbps, 48kHz
6: AC3 Surround, English, 2.0 channels, 224kbps, 48kHz
7: DTS, English, 2.0 channels, 768kbps, 48kHz
8: Subtitle (PGS), English
9: Subtitle (PGS), French
10: Subtitle (PGS), English
11: Subtitle (PGS), French
12: Subtitle (PGS), Spanish

The video track is not correctly identified.

Using bdinfo.exe on the disc shows:

2160p / 23.976 fps / 16:9

Using the new tsMuxer.exe on the disc shows:

Profile: Main 10@5.1 Resolution 3840:2160p Frame rate 23.976

I don't know if tsMuxer.exe is just faking the detection or can see something that eac3to.exe and bdinfo.exe can't. If I use txMuxer.exe to demux/remux the output is still detected the same way as "unknown parameters".

Is there something that eac3to.exe is missing or is the video track just not made right? This is the first time I have seen this message.

Last eac3to version is from 2017, the new tsMuxeR, updated at present, maybe can do a better job.

The last version of BDInfo is from 2018.

Downmix clipping (7.1 -> 5.1)

I'm not sure whether this issue has already been covered here before as on a pre-search, the closest I found was only this post.

With several movies now which provide a 7.1 mix such as "Dredd" or "Ford v Ferrari" (and no matter whether Dolby TrueHD or DTS-HA MA), I encountered clipping when downmixing to 5.1. It goes undetected and eac3to doesn't issue a second pass. However, if I inject any volume change, like -0.1dB, then the audio all of the sudded isn't only treated as a 64 bit source (probably due to the internal workings of the libav/ffmpeg decoder's gain control), but also clipping is correctly recognized, triggering a second pass with an often more severe volume reduction.

To me, this doesn't make any sense as the clipping should be recognized without any manual gain intervention by the user.

Either I missed something here or this is a real bug in eac3to.

Yes, I've come across such clipping as well, so I usually check the output in Audacity. You could decode the 7.1 to w64 with eac3to and then use BeHappy to downmix to 5.1. It uses AviSynth, like this:

Code:
LoadPlugin("nicaudio.dll")
LoadPlugin("AudioLimiter.dll")
a=RaWavSource("file.w64", 1)
\.ConvertAudioToFloat()

flr = Getchannel(a, 1, 2, 3, 4)
blr = Getchannel(a, 5, 6)
slr = Getchannel(a, 7, 8)
sur = MixAudio(blr, slr, 1.0, 1.0).SoftClipperFromAudX(0.0)
return mergechannels(flr,sur)
