Here we are talking about eac3to GUI's.

The .h265 extracted with eac3to v3.32 from this sample don't play fine.

Extracted with MkvExtract is ok.

Just-so-you-know...

I downloaded your sample, transferred it to an USB pen-drive and can confirm that it plays fine in my LG television.


Cheers

Thank you, MeGUI seems to be working great. It looks like I can finally move away from Clown_BD.

I am still confused about how eac3to handles Atmos tracks, though. Is an Atmos track the same thing as a TrueHD track, or is eac3to converting Atmos to a TrueHD track for compatibility reasons? Dolby's naming convention isn't helping me understand it any better.

Well, looks like eac3to and MeGUI has failed, too. This is what an UHD HEVC file looks like when muxed to MKV. Only MKVToolNix appears to do it correctly. (Actually, maybe the problem lies with MKVToolNix in not handling separate/extracted files correctly...)

The uploaded sample work fine, but if you extract the .h265 with eac3to and play it, even re-remuxed to mkv, fails (like the Megalith image).

A Atmos track is a TrueHD track with extra metadata than only a receiver with Atmos support (and ceiling speakers) can understand.

The metadata remain in thd extracted by eac3to/mkvextract.
Standard receivers ignore that metadata.

Another sample with problems.

Remark the different size of extracted .h265
Code:
15/10/2017  22:03       177.693.906 Arrival UHD Sample.mkv_ 0.h265  (mkvextract)
15/10/2017  21:59       157.722.039 Arrival UHD Sample.mkv_1eng.h265 (eac3to)

Dear madshi

I have used eac3to to identify my .mkv files and I have got such results:

Quote:
MKV, 2 video tracks, 1 audio track, 2:15:58, 24p /1.001
1: h265/HEVC, English, 2160p24 /1.001 (16:9), 10 bits
2: h265/HEVC, English, 1080p24 /1.001 (16:9), 10 bits - Dolby Vision Enhancement Layer
3: DTS Master Audio, English, 7.1 channels, 24 bits, 48kHz (core: DTS, 5.1 channels, 1509kbps, 48kHz)
Source disk has got DTS:X audio track, why it's not identified as DTS:X, but DTS Master Audio? The next .mkv file, which I show results below, has got in source disk Dolby Atmos and in the .mkv file it's Dolby Atmos too, which is correctly identified.

Quote:
MKV, 2 video tracks, 1 audio track, 2:34:39, 24p /1.001
1: h265/HEVC, English, 2160p24 /1.001 (16:9), 10 bits
2: h265/HEVC, English, 1080p24 /1.001 (16:9), 10 bits - Dolby Vision Enhancement Layer
3: TrueHD (Atmos), English, 7.1 channels, 48kHz, 32ms
My second question, why there is not core embedded in track 3 TrueHD (Atmos) like in first .mkv file for DTS Master Audio (core: DTS, 5.1 channels, 1509kbps, 48kHz)?

Thank you in advance for your support.

Sincerely

Because eac3to can't detect DTS:X, maybe can be a feature request (not important for me, because can be extracted preserving DTS:X info, and can be decoded like standard DTS-MA)

Quote:

Because TrueHD don't have any 'core', like DTS-HD have.
The AC3 track interleaved with TrueHD track is only possible in m2ts container, in mkv must be a different track.

Posts about E-AC3+Atmos moved to new thread E-AC3+Atmos

Because eac3to can't recognize the tracks like Atmos.
BTW eac3to can decode them like standard 5.1.

When eac3to was "fixed" not to crash when Atmos metadata are contained, the fix only meant to properly ignore them.

But I believe you can't remove the Atmos part and keep only the True HD part, thus it's not ignored but treated as is.

"Removing" would not be "ignoring". It just ignores if its present or not, and copies the entire TrueHD as-is. Removing it would require modifiying the entire TrueHD stream, since its not a separate sub-stream or anything like that, but actually integrated into the TrueHD stream itself.

Hi! What's the difference between using and not using the -down16 option? I tried both way, but the output is still has 16bit bit-depth but the md5sum's are different: https://vgy.me/Tflfue.png

If you use the -down16 option, the precision of your input WAV is first reduced from 32 bit float down to 16 bit integer, before encoding it to AC3.

Omitting it, more or less the full input precision is encoded to AC3.

And what do you suggest? Should I use it or omit it?

Why would you want to possibly reduce the precision, thus quality, in the middle of a conversion? If you omit it, the precision might be better than just 16 bits.

The change of the stream order breaks simple parsing.

@madshi
Could you add the eac3to stream number at the end of the PID info line for each PID?
