Quality based AAC encoding will produce a variable audio bitrate. That's fine, the MP4 and MKV containers can handle that.

I was ripping some UHD's which are giving me a hard time for some reason, and at first I was using version 3.34 which is working without issues, but I noticed 3.36 was released too.
Normally I use MKVToolnix, since that works fine for me, and eac3to to list the playlists I might need to rip.

But with version 3.36 I am running into some weird issues when trying to rip.
Both video and audio show these messages:
"This video conversion is not supported", "This audio conversion is not supported."
This is for only ripping either the video track (both video and Dolby Vision) or audio track.

Going back to version 3.34 and it works fine as before.

I don't have any DLL's replaced, so pure unzip and use.

Am I doing something wrong?

Example:
Quote:
D:\Tools\eac3to>eac3to.exe f: 2) 2:d:\videos\02video.hevc

I'm trying to demux .mkv file with positive audio delay using eac3to. I've noticed that after delay is fixed distortion audio is added/occurs at the beginning, why is that and how to avoid it ?

Only silence frames are added at the begining, if there are distortion must be present in the original audio.

Use mkvextract to extract the audio without apply the delay.

There's no distortion noticeable if i extract audio with mkvextract, so it's definitely eac3to issue. It should add silence frames where audio is missing but instead it adds buzzing sound. Does it make any difference if positive delay isnt fixed when demuxing/remuxing files ?

Edit: It doesnt work well if delay isnt fixed, because it shifts the audio for a few frames which doesnt make it synced as original.

Please upload the log of eac3to when extract/demux the orginal file.

Hello, I have a remux of a UHD bluray of a live concert. I am converting the audio to flac. I used MKVtoolnix to extract the audio to MKA, exported by chapters. Out of the 16 "tracks" that I was left with two of them fail to convert to flac. I am using the UsEac3To gui running a simple command of DTS to FLAC. This is the error I am getting on the failed files.

MKA, 1 audio track, 0:05:15
1: DTS Master Audio, English, 5.1 channels, 24 bits, 96kHz
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
"DTS-HD Master Audio / 5.1 / 96 kHz / 6853 kbps / 24-bit"
[a01] Extracting audio track number 1...
[a01] Decoding with libDcaDec DTS Decoder...
[a01] libDcaDec reported the warning "Failed to parse XLL". <WARNING>
[a01] libDcaDec output changed from 6 channels, 96kHz to 6 channels, 48kHz. <ERROR>
Aborted at file position 262144. <ERROR>

Can anyone help a guy out?

Maybe there are problems when mkvextract (designed to cut by video frames) cut audio by chapters.

Or there are some corrupt data, or not supported by libDcaDec.

With UsEac3to you can try the conversion with ffmpeg decoder:

Load the problematic file in UsEac3to and click in 'A/V Recode', select the first option 'Decode,Lossless.Wavdts' and 'flac' like output.
Run or Enqueue
(with Enqueue a .log file is created to attach here)

Ok so that worked, but now it is messing with the file. We went from 96khz to 48khz and the bitrate dropped from 6,000 to 3,000.

I also tried making a wav, but the same thing happened. Strange. I might just manually extract the section with MKVtoolnix and see if I can then use the method I did with the original files?

ffmpeg log show something like the:?
[a01] libDcaDec output changed from 6 channels, 96kHz to 6 channels, 48kHz. <ERROR>

The 96 to 48 KHz change?
Try decoding to w64 the full file without split by chapters.

I was able to decode the entire file to w64. Not sure what to do with that. Manual splitting?

Then the problem is when mkvextract cut the full DTS.
I don't know how cut DTS/W64 by chapters then only method I can suggest you is manual split.

Sems there are only 2 parts with problems make the new flacs with:

Thanks for the help, I was also able to rip a full quality flac file of the entire film. So I cam mess with that as well.

I'm currently trying to sync a second audio track to a series. Movie is 23.976 fps, Audio source 25fps. Usually it should just be -slowdown or -25.000 -changeto23.976. This worked for previous seasons but now the resulting audio file is too short, resulting in async audio. It seems to be drifting continuously over the playtime. So changing the source or target framerate should fix this. Is there any way to make eac3to use non-standard framerates? It does not seem to accept 25.002 as source or 23.970 as target.

It is not possible with eac3to.

Try with ffmpeg -i "INPUT" -af "atempo=0.959041" ...
with (slowdown) 23,976/25 = 0.959041 (change as you need)

Thanks, that worked. I tried BeSweet before but that produces unpredictable output.

It is apparently not possible export the dolby video stream from a uhd using version 3.36 anymore. This was working in 3.34. I am using eac3to in conjunction with megui, which it will now throw an error.

Then use v3.34 if the changes in the v3.36 don't work for you:

v3.36 2022-05-08
* fixed: UHD Blu-Ray support didn't work with newer releases
* fixed: on some OSs there were crashes
* fixed: libav command line output hooking wasn't working properly
* added special handling for TrueHD seamless branching
* 2nd pass for audio gap fixing is auto-disabled for (UHD) Blu-Rays now
* libDcaDec: updated to 0.2.0

(Preserve the libDcaDec.dll 0.2.0)

Yes, thats exactly what I'm doing. I thought perhaps it would be nice to give feedback, so that it is known that there was a regression.
