Anybody know whether the new Arcsoft 3 will continue to provide the necessary decoders for eac3to DTS decoding or whether the architecture has changed?

Yeah maybe have they made it impossible to use their filters outside of TMT...?

eac3to FLAC compression

I tried to encode via FLAC CLI (revision 1.2.1b alias the latest official release) with --no-padding together with the --best switch. Despite the fact that madshi has included only version 1.2.0 of libFLAC.dll with his eac3to package the only differences occur in the metadata tags at the beginning of files. Raw encoded audio data are bit-to-bit identical.

How to make FLAC CLI encodes bit-to-bit identical with eac3to
First download the latest FLAC library package and replace libFLAC.dll in the eac3to folder with the downloaded one.
Run your CLI encoder with the following options:
Code:
flac.exe --best --no-seektable --no-padding --tag=WAVEFORMATEXTENSIBLE_CHANNEL_MASK=0X0 --tag=VALID_BITS=16 --tag=HDCD=0 inputfile.wav
You will have to change the tag values accordingly for multichannel and/or different bitdepths, my example demonstrates ordinary 16-bit stereo WAV.

Duplicate Subtitle Tracks

When extracting from a VOB, EAC3TO 3.14 is frequently outputing duplicate subtitle tracks - for instance

Movie - 6 - Subtitle (DVD), 1857 captions.sup and
Movie - 6 - Subtitle (DVD).sup

The two files have identical contents.

The command line is
EAC3TO vts_01_1.vob+vts_01_2.vob+vts_01_3.vob+vts_01_4.vob+vts_01_5.vob+vts_01_6.vob Movie.mkv -seekToIFrames -lowPriority

Hi madshi.

Could you please take a look at this file.

http://d01.megashares.com/?d01=72e4388

It's recorded from DTV. It has 5.1 channels during main broadcast and switches to 2.0 channel during the ad breaks.
Converting to flac results in the audio during the ad breaks being high pitched.

I've just tried it using a 2hr+ 5.1 24 bit source and don't find any significant difference in size between flacs produced by eac3to and soundout.

Are you sure the audio is not being corrupted somewhere in your avisynth / soundout chain? If you convert your target flacs back to wav are they identical?

Use DelayCut to split the ac3 source.

Sorry to bother, some eac3to -decodeHdcd questions ;

Any reason to why eac3to with -decodeHdcd switch gets 6 dB gain lower than standard decoding ?
If so, is it OK to add +6dB as a switch while doing conversions ?
Madshi, Is there a possibility to add -deEmphasis switch option to eac3to ?

Best regards,

narshorn

This might be troublesome. All the GUIs out there don't expect the file names to have such a delay added to them. So if I did that, it would probably break all GUIs. Also I'm not sure if it's really worth it. I mean e.g. 9ms are really small...

The bluaray is not a seemless branching movie and is a single m2ts. Also running latest anydvd.

If you run into such a problem, always try using the AnyDVD HD built in ripping tool to copy the disc to harddisk first and then run eac3to on the harddisk folder. If that also fails, the disc might be faulty.

Most Blu-Rays are 24/1.001. Yours is 24/1.000. That is unusual. eac3to just posts this warning to alert you that the framerate used by this Blu-Ray is strange. You can ignore the warning. But be aware that you might run into stuttering issues when playing back this Blu-Ray.

libav MP3 decoding is already supported. Vorbis and AAC are not. The AAC decoder is not feature complete yet, so I'm waiting until it is. Vorbis might be added sooner or later...

OTOH transcoding LPCM in FLAC gives proper sound levels, identical to DTS core

if anyone's got a clue, I'd love to hear it. thanks!
Maybe your DTS decoder is not working properly? Don't know...

IIRC this movie had several playlists. The main playlist has messed up audio. Try some of the other playlists. At least one of them works fine. This is a mastering problem, not an eac3to bug.

The original audio track has a constant bit depth of 24 bits.
Caution: The WAV file is bigger than 4GB.  <WARNING>
Some WAV readers might not be able to handle this file correctly.  <WARNING>
eac3to processing took 9 minutes, 41 seconds.
Done.
If I then run eac3to on the output wav file I get:

------------------------------------------------------------------------------
The format of the source file could not be detected.  <ERROR>
I've been trying to find out why this file does not work and other apparently similar ones do and the difference seems to be the amount of silence at the beginning of the file. This file contains 11866608 bytes = 6.86725 seconds of silence at the beginning. I tried editing the first six samples to non-zero values and it's then detected by eac3to.
This was caused by the HDCD decoder not being able to lock unto the stream due to the many zeroes. Will be fixed in the next build.

Currently not in any automatic way. You could try splitting the m2ts file manually by using a hexeditor or by using some other external tools.

http://rapidshare.de/files/46162759/extract.h264.html

- The sample is a part of a h264 file extracted directly from blu-ray using eac3to
- When performing the following set of commands on this sample:

Code:
eac3to extract.h264 extract.mkv
eac3to extract.mkv 1: extractfrommkv.h264
then you will notice that the result file "extractfrommkv.h264" is different from the original "extract.h264".

Looking a bit more in detail there is a sequence of 162 bytes added at specific places in the file, starting with the following 34 bytes:

Code:
00 01 27 64 00 29 AC 7B 01 E0 08 9F 97 FF 00 01 00 01 10 00 00 3E 90 00 0B B8 08 40 00 00 00 01 28 EA
The sequence is the same throughout the file and removing it will give back the original "extract.h264".

The issue has been introduced as of v3.07 (v3.06 works fine), and I think it happens only with AVC/H.264 encoded files with 2 Reframes. Did the test on 4 different films (directly from blu-ray), all with 2 reframes, and they all had the issue, i.e. a lot of artifacts during very fast-moving scenes.
Did some other tests with VC1, MPEG2 and higher-frame H.264 encoded files and did not find a difference between the files before and after the 2 eac3to steps provided here above.
Thanks for the report. Will be fixed in the next build. FWIW, the MKV file is just fine. It's just the MKV h264 extraction which produced incorrect results.

Using "fps=23.976" is wrong. You should encode with 24/1.001 instead. tsMuxeR's conversion to 24/1.001 was buggy, that's why eac3to didn't like that, either. This problem is fixed in the latest tsMuxeR version, though.

eac3to is just writing to disk what the HDCD decoder outputs. Of course you can change volume, but please be aware that changing volume involves floating point math, so basically the result will not be 20bit integer, anymore. Instead it will be 64bit floating point. You can then dither that down to whatever bitdepth you want. eac3to by default dithers down to 24bit.

Any chance of swapping those letters in a future update?
And next week someone else uses a different encoding software which expects "SL" and "SR" or something completely different and I have to change names again? I don't think there's a fixed standard on how to name these files. If there was such a standard, I'd be happy to make use of it. But as long as different encoders expect different names, I'll not adjust to one specific encoder.

You could try:

(1) Does the DTS decoder still work for eac3to?
(2) Does it handle those 7.1 DTS-MA tracks with funny speaker placement correctly? That was the only thing that could be improved. Apart from this the old ArcSoft DTS decoder was already pretty perfect.

How do you know that? You could try pressing "Ctrl+C" when the 2nd pass starts. Depending on how the 2nd pass is executed, this might get you what you want. Eventually eac3to has already deleted first pass results, though. Depends on the circumstances...

Do you have this problem when reading directly from the physical BD? Or when reading a folder structure? Newer eac3to versions use memory mapped file read for physical drive access because that was *a lot* faster. For folder reading the same logic should be used as before, though.

Whenever I have attempted to do this, the audio is always wildly out of sync. I'm assuming that either the video or audio is continuous, whilst the corresponding audio or video isn't: often there are long stretches of blank video between the PIP segments.
I've never really tried. But as you say, I think PIP video sometimes has big (very VERY big) areas where there's no video content at all, while secondary audio usually is continuous. That of course makes things very difficult. However, I imagine eac3to should detect the gaps in the video stream and try to repair them when muxing to MKV?

As far as I can see, the 3 episodes are 4.m2ts, 12.m2ts and 13.m2ts. Strange enough, there is one playlist for 4.m2ts and one for 13.m2ts, but none for 12.m2ts. So that's the simple reason why eac3to "failed to detect" one episode. eac3to does not detect anything, it just lists the available playlists. If there's no playlist for an episode, naturally eac3to will not list it.

The DTS software creates files with an extra 140 bytes of header information at the beginning of the files. This information is stripped off when the DTS is used on a final disc, so if you rip DTS off a Blu-Ray disc, this data is not there. Thus, eac3to doesn't recognize a DTS file with this information... The header isn't vague, the first 8 characters are DTSHDHDR. It would be great if the software could be updated to recognize DTS files with this header information still attached.

I encoded a 7.1 test stream for someone else on the forum, and a member discovered the problem when trying to use eac3to on the file. The files are here:

There's a DTS-HD High Resolution stream (I don't see this used very often, basically DTS that can go up to a 3mb bitrate), and a DTS-HD Master Audio stream included.

[...]

Follow-up to this:

There's more to this than I thought. Apparently the header info is different sized depending on the type of DTS file you've encoded... The header includes the 8 bytes following the string STRMDATA, that seems to be consistent with all the files I've encoded so far.
Interesting. It seems there's a whole file structure. It's very easy to understand, though, so it should be easy adding support for that. Well, "easy" means "not difficult". It does cost some time, though, so it may have to wait a while.

Then your SoundOut setup is probably broken and does some damage to the audio data. If you want to be sure, you can upload the first 50MB of the eac3to created FLAC file and the first 50MB of the SoundOut created FLAC file. I'll have a look at them then.

This sounds like too much of a delay, but off hand I can't remember what the audio delay reported by DGIndex was. Does anyone know how accurate eac3to's parsing of matroska delay values is?

Eduit: Mkvinfo -v shows that the audio starts 16ms after the video, which jogs my memory and I think was the delay I applied at muxing. What's going on here?
Is it possible that the video stream doesn't start with a proper sequence header? eac3to always calculates from the first *displayable* video frame.

eac3to v3.15 released

http://madshi.net/eac3to.zip

Code:
* "24.975" is now interpreted as "25.000/1.001"
* Blu-Ray "sup" are demuxed with DTS set to 0 again, proper fix will come later
* fixed: error code not set for "source file format could not be detected"
* fixed: audio resampling from/to 24.975 didn't work properly
* fixed: WAV files beginning with lots of zeroes were sometimes not accepted

I am always reading from a folder on HDD. However, CrossOver maps folders on my Mac HDD to a device in Windows. For example, if I read from '/Volumes/HardDisk1/BD/Movie' it is mapped to 'D:\BD\Movie'. I am pretty sure the file mapping is causing the problem. Maybe you can fallback to normal IO if filemapping fails?

* Blu-Ray "sup" are demuxed with DTS set to 0 again, proper fix will come later

Can someone explain this please ?
Does it means we should wait the proper fix of eac3to to demux sup file ?

If I knew how to detect that? How does your eac3to log file look like?

If you want to convert those sup files to SRT, there's no problem. If you want to remux them into a m2ts structure, then with some movies the current sup files produced by eac3to won't display correctly on some standalone players.

So if i have already demuxed the subtitles and when the problem gets fixed can i run the demuxed subs back through eac3to and be fixed then or do i have to go back to the blu-ray it self and do it again?
