Still Having Problems with TrueHD

[rica]

Hi guys.
Are you supposing you get bit-perfect output?
I don't think so.
This is why i did feature requests with no responses:

I thought original thread was about backing up blu ray to m2ts retaining hd audio? If so, i remuxed iron man straight from disk, to a single m2ts, looked ok and played fine on the pc, have not made blu ray output and tested via disc, i could try, but have no blu ray burner.

MUI Generator is a component of Sonic Scenarist. You can't download it and Scenarist is an incredibly expensive piece of software.

and when he says incredibly he means it..like 24,000$..though older versions have been selling for around 5k.

Um..I dont see how that program effects TrueHD at all as it just is some front end that uses TSmuxer which means it would have the same issues as TSmuxer with TrueHD.

The issue is not that TrueHD wont play on pcs it does, it just does not play on standalone players (PS3, Blu ray players). And the program you are showing uses TSmuxer to mux so it would have the same issues with TrueHD. And reading the thread it doesnt handle Truehd any better sugessting runing through TSNP after you run it through TSmuxer which may or may not work.

[spida_singh]

Im sure i read in the posts that this now uses it's own muxer, i maybe wrong, ill check properly and find out what this tool is capable of.

[asarian]

unfortunately I confirm your frustration,
I've spent a whole week trying to backup/downsize The Dark Knight, that has the "infamous" True-HD track, using all sort of methods: Tsmuxer, Tsremux, Tn4sp, eac3to to PCM (all channels mixed up),

Odd. I converted the "Dark Knight" TrueHD track to LPCM, using eac3to, just fine.

[asarian]

I think with good quality equipment, the difference is quite substantial. I mean no disrespect here but unless you do have a high end setup, then it may be best to not make assumptions based on the differences heard with equipment not able to present lossless audio in it's full glory.

I wouldn't even consider myself an audiophile per se, but even I can hear a clear difference between, say, a DTS stream @ 1536Kbps and 640Kbps AC3. And AC3 really, really loses out to TrueHD/DTS-MA. No comparison. Most of which I think Jamos actually agrees with. :) Just sayin'.

[Ryu77]

Has anyone at all been successful remuxing The Dark Knight with VC1 video track and Dolby TrueHD audio track?

I have tried so many different ways and still no success. It must be possible as there are torrents available to download a main movie remux with TrueHD. These torrents state that file size is about 30GB which is exactly what I come up with except the TrueHD track wont work with mine.

By the way Jamos, the Sonic method we discussed earlier looked as if it was going to work. At the point of what looked like the MUI Generator was about to finish doing it's job, it threw an exception and closed.

What do you want to play it on? For PCH playback TsRemux worked for me, as did eac3to+TsMuxeR+ts4Np.

[peterjcat]

Im sure i read in the posts that this now uses it's own muxer, i maybe wrong, ill check properly and find out what this tool is capable of.

That's right, ToNMT uses tsMuxeR only for HD DVD conversion and has its own routines for Blu-ray. It preserves the TrueHD rather well including in multiple-M2TS files (it may not correct TrueHD gaps/overlaps, but this doesn't seem to be possible even with eac3to).

[Ryu77]

What is PCH? Is that Pop Corn Hour?

I have heard of a few saying that it will work on a PC but not when burnt to disc and played on a stand alone. I am not after this, I would like a fully compliant BD structure.

I just tried the "eac3to+TsMuxeR+ts4Np" method and ArcSoft TotalMedia Theatre wont even start playing the movie, it just hangs.

Sorry, yes PCH is Popcorn Hour. It looks like ts4Np may do something that fixes TrueHD for the PCH (and other networked media players?) but doesn't help with making a compliant BD.

Just in case : the issue has been fixed.

CLI of tsMuxer is available here (ftp://213.221.6.90/tsMuxer/). No need to replace the GUI.

Sorry, the issue isn't fixed as far as I'm concerned.

I tried again with the new tsMuxer (1.8.18), the audio still sounds like crap on playback from a standalone (Sony BDP-S350) and from a PCH when using TrueHD.

This is Iron Man region 1, the video (.h264), audio (.thd+ac3), and subtitles (.sup) all extracted from the original BD using eac3to.exe v3.11. Remuxed back together using tsMuxer 1.8.18, using the following .meta file:

MUXOPT --no-pcr-on-video-pid --new-audio-pes --blu-ray --vbr --custom-chapters=00:00:00.000;00:09:06.171;00:18:00.579;00:26:49.942;

S_HDMV/PGS, "T:\IM\origSub.sup", fps=23.976, lang=eng

Audio sounds exactly the same as it did with the old version of tsMuxer - very distorted dialogue, scratchy/interference-laced center channel, very little LFE output.

Sorry, but it looks and sounds to me like the writers of tsMuxer haven't fixed anything with this release.

[idbirch2]

Well it works fine for me, I've done several TrueHD titles now and they all play fine on the PS3. Maybe you should try removing a couple of non-standard variables to see if they are causing your problem. First, ditch the custom chapter list and second, rename your TrueHD stream to *.thd instead of *.thd+ac3.

I will give that a try.

But didn't TrueHD always work on the PS3, even before the new v1.8.18 of TSMuxer? I thought it was only the standalones that were affected.

[idbirch2]

No, PS3 has always suffered as much as standalones. All the truehd titles I tried prior to 1.8.18 resulted in no sound. Let us know how you get on as I'd be surprised if standalones still have the problem.

Iron Man TrueHD works fine for me on the PCH A110 with the new version of tsMuxeR using the same process (eac3to+tsMuxeR) -- before the new version I didn't get any sound at all. Is your receiver showing TrueHD and everything?

Also make sure you've turned off DRC/Quiet Mode/Late Night Mode on your receiver after you've started the movie playing -- Iron Man is known to trip DRC by default (maybe even if you have your receiver's DRC turned off by default) and badly implemented DRC may give the symptoms you describe.

[SomeJoe]

I tried again with the following .meta file:

MUXOPT --no-pcr-on-video-pid --new-audio-pes --blu-ray --vbr --vbv-len=500
V_MPEG4/ISO/AVC, "T:\IM\origVideo.h264", fps=23.976, insertSEI, contSPS
A_AC3, "T:\IM\newAudio.thd", lang=eng
S_HDMV/PGS, "T:\IM\origSub.sup", fps=23.976, lang=eng

i.e. No chapter points, audio file renamed to .thd instead of .thd+ac3.

This gives the same results, on BOTH a Sony BDP-S350 and a PCH A110.

The only difference I notice between this version of TSMuxer.exe (v1.8.18) and the old one (v1.8.8) is that the previous version would give me no audio at all on the AV receiver if I only used TSMuxer by itself. If I then remuxed with TSRemux/TS4Np, then I get the TrueHD to appear on the AV receiver, but the audio is distorted.

This new version of TSMuxer eliminates the need to do the TSRemux/TS4Np step -- I get TrueHD showing on the AV receiver directly from the output that TSMuxer makes, which is a small step forward. But the audio is definitely and obviously distorted. The initial dialogue in the Hummer at the very start of the film is unintelligible. It's perfectly clear when decoded to PCM.

I have my receiver's DRC turned off. As far as I know, it is not applying it. (This is a Pioneer VSX-1018AH-K, by the way, both the Sony BDP-S350 and the PCH A110 are hooked to it via HDMI). However, this is much more than a DRC problem. The audio is not just quieter or less pronounced, it is distorted (in some places to the point of audible static).

I'm going to try another film. I own the original BD of Top Gun, which has both a TrueHD track and a DTS-HD MA track. I'll make 2 versions, one with the TrueHD track and one with the DTS-HD MA track and compare them. The DTS-HD MA track is a bit louder on the original, but otherwise should be identical.

I just don't understand how everyone can be saying that its working perfectly. I don't have particularly discerning ears or anything. In fact, for me, lossy DTS and the lossless audio formats sound identical, and I have a decent 5.1 system here (The Pioneer VSX-1018AH-K is exquisite, and my speakers, while about 10 years old, are not bargain basement by any means, but aren't Aperions either). The distortion is striking and very obvious -- not at all subtle. I don't see how anyone could miss it.

Which either means I'm doing something wrong, or ... well, I can't think of another reason. :-)

[idbirch2]

Hm, well someone else has reported success with a Sony s550 on the Slysoft forums and I'm sure I've seen someone mention it works with their PCH too so you are definitely doing something wrong. You say you "tried with the following meta file" - does that mean you're makeing the .meta file manually and running from a command line? If so, use TSMuxerGUI instead. If that's not the problem, I don't know what you're doing wrong.

I have used tsMuxer.exe from the command line before with some automated tools, but for this test, since I'm having problems, I've been using the tsMuxerGUI.exe to do everything. The .meta files I've posted are what the tsMuxerGUI.exe is creating.

It did occur to me that perhaps the TrueHD stream/muxing is not quite compliant, but close enough that most things don't have a problem with it -- except my Pioneer AV receiver. Does anyone else have a success story with TrueHD and the new TSMuxer and is using this particular AV receiver?

To test this theory, I'll make a small change tonight. I have my Sony BDP-S350 and my PCH A110 set to bitstream the audio to my Pioneer. Tonight I'll set them up to decode the audio to PCM internally and send PCM to the Pioneer and see if there's a difference.

Is it 16 bit or 24 bit truehd? I have seen this issue with 16bit truehd.

[SomeJoe]

OK Bingo!

I set my Sony BDP-S350 to decode the audio internally to PCM instead of bitstreaming the audio to the AV receiver. This immediately fixed the distortion issue. I tried the same thing on the PCH A110, that also fixed the distortion issue. Both playback devices claimed they were decoding TrueHD, not just the AC3 core. AV receiver showed PCM 5.1 (from Sony) or 7.1 (from PCH).

However (there's always a caveat, isn't there?), I also have the audio from this movie (Iron Man) done as lossy 1536Kbps DTS (extracted as PCM using eac3to.exe, and encoded using SurCode DTS). So I've been comparing the following:

1. AV receiver-decoded TrueHD from the original BD (source: Sony BDP-S350)
2. AV receiver-decoded TrueHD after being remuxed by TSMuxer.exe (source: Sony BDP-S350 and PCH A110)
3. Playback device-decoded TrueHD after being remuxed by TSMuxer.exe (source: Sony BDP-S350 and PCH A110)
4. AV receiver-decoded DTS after being remuxed by TSMuxer.exe (source: Sony BDP-S350 and PCH A110)

These result in the following sound fields (subjective):

1. Flawless. Crisp dialogue, impactful LFE, wide and defined surround field.
2. Distorted, low-LFE, little surround effect, and possible channel-mapping problems (exchanged Right Front and Right Rear?)
3. No distortion, crisp dialogue. LFE sounds less impactful, but could be the result of inability to control Dolby DRC on the Sony and PCH. But, surround field sounds flat. Not very much positioning of sound.
4. To my ears, sounds identical to #1. Crisp dialogue, impactful LFE, wide and defined surround field.

I'm going to do another TrueHD movie to compare, but I only own the following BDs with TrueHD tracks:

1. Iron Man
2. Top Gun
3. Risky Business
4. Starship Troopers
5. Blade Runner (Final Cut)

It will take me some time, because to compare these on the Sony BDP-S350 I have to burn to a BD-RE which is slow.

At this point, my preliminary conclusion is that the TrueHD muxing the TSMuxer.exe v1.8.18 is doing is not 100% compliant. It's close enough that some devices can play it mostly correctly, although there is a loss of surround fidelity, and some devices have severe problems resulting in distortion.

I would like others who may share my hardware/equipment and/or the BDs that I listed above to conduct their own similar tests to gather some more data.

Is it 16 bit or 24 bit truehd? I have seen this issue with 16bit truehd.

As far as I know, TrueHD always stores everything internally as 24 bit. The master source material may not have had that much resolution, however.

[peterjcat]

OK Bingo!
I set my Sony BDP-S350 to decode the audio internally to PCM instead of bitstreaming the audio to the AV receiver. This immediately fixed the distortion issue. I tried the same thing on the PCH A110, that also fixed the distortion issue. Both playback devices claimed they were decoding TrueHD, not just the AC3 core. AV receiver showed PCM 5.1 (from Sony) or 7.1 (from PCH).


The PCH is only decoding 2 channels of TrueHD (it can only ever decode 2 channels of anything to PCM) and leaving the other channels blank, which would explain why the LFE and surrounds were affected on that device at least. Did you really hear no difference between the Sony and the PCH?

I would tend to agree with your conclusion that tsMuxeR is not 100% compliant, or else the Pio is overly sensitive, or both. But have you tried playing an unremuxed Blu-ray M2TS file via the PCH? Just for some more confirmation.

[jamos]

No, there are 16 bit Truehd streams out there (Appaloosa is one example).

You are bitstreaming through your HDMI to a True-hd capable decoder on your reciever and not a optical cable, correct?

You are absolutely correct, sir. Well done, and excellent suggestions.

OK, here are my latest findings:

1. Yes, the PCH, when set to decode TrueHD internally, only decodes to 2-channel PCM (even though the receiver display shows 7.1 being received, the C, SL, SR, BL, BR, and LFE channels are silent. Only FL and FR are active). This explains the lack of surround field during playback in that mode.

2. When set for internal decoding and PCM output, the Sony's internal DRC was interfering enough with playback such that the surround field wasn't audible until volume was turned up significantly more than what I was listening to when the audio was bitstreamed. After raising the volume to a proper level, the surround field sounds correct here.

Thus, the conclusion is that the surround field and LFE output are proper when the decoding is done by the Sony (and probably by the PCH as well, but that's impossible to tell since the output is 2-channel).

3. I tried taking the original .m2ts file from Iron Man (00010.m2ts) and playing it back on the PCH without anything being done to it. This plays back perfectly on the PCH when bitstreaming the TrueHD to the Pioneer.


To me, this proves exactly what you said: 1) The muxing isn't 100% compliant, or 2) The Pioneer has a flaw/bug in TrueHD decoding, or 3) some combination. I would wager #1, as I have not had any problem with any original BDs containing TrueHD tracks.

[SomeJoe]

You are bitstreaming through your HDMI to a True-hd capable decoder on your reciever and not a optical cable, correct?

Yes, of course. The Pioneer would not show TrueHD on the display unless the audio was coming over HDMI. Both the Sony BDP-S350 and the PCH A110 are connected via HDMI.

[lchiu7]

OK Bingo!

I tried the same thing on the PCH A110, that also fixed the distortion issue. Both playback devices claimed they were decoding TrueHD, not just the AC3 core. AV receiver showed PCM 5.1 (from Sony) or 7.1 (from PCH)...

I had no idea the PCH A110 could decode TrueHD (or DTS HD Master). I thought with its HDMI 1.3 connection and internal firmware, all it could do was bitstream those lossless codecs relying on your AVR to decode. The PS3 OTOH decodes both codecs internally and outputs LPCM

[SomeJoe]

I had no idea the PCH A110 could decode TrueHD (or DTS HD Master).


Yes, it can, however, as posted prior, it will only decode the front left and front right channels to PCM (2.0 sound). So you do not get 5.1 when in this mode.

To get 5.1 from the PCH with these audio codecs, you must bitstream.

[lchiu7]

Are you sure it's not just outputting the core AC3 stream?

[SomeJoe]

It claims on the on-screen display that it is decoding TrueHD. Whether that's true or not, I have no idea.

[lchiu7]

It claims on the on-screen display that it is decoding TrueHD. Whether that's true or not, I have no idea.

I suspect not since there would be significant code in the PCH to do that. After all it took Sony in the PS3 some programming effort to decode TrueHD and output it as PCM and they have significantly more resources than Syabas.

I have a A100 and if I play a title with TrueHD audio I don't get any sound. Now I am not using HDMI but optical but if it were truly able to handle TrueHD I would have thought it would output the AC3 core over optical as the PS3 does.

I have seen notes in the Syabsa forums that the A110 won't output TrueHD even if it's in the track unless there is a companion AC3 track even if you don't need it. Worth a try

Well, it's really a moot point anyway. No matter which portion of the TrueHD stream it's decoding (the lossless part or the core), it either results in 2-channel output (when decoding internally), or distorted audio (when bitstreaming), neither of which are acceptable.

I'll continue to use PCM or DTS audio until such time as TSMuxer.exe is 100% compliant when muxing a TrueHD stream.

According to the latest threads on the NMT forums, talking about the tonmt tool which was written specifically to get HD content to the PCH, TrueHD works fine. You might want to check it out. Also the latest beta release of tsmuxer has fixed TrueHD problems when targetting AVCHD content for the PS3.

Yes, I tried ToNMT and it seems to mux TrueHD perfectly. But it only creates a .ts stream, not a Blu-Ray structure suitable for burning.

Again, as I've discussed in this thread, TSMuxer.exe does not create a proper stream with TrueHD (yes, even the new version, 1.8.18).

The "QuickFix.cmd" batch file (which calls a Java class) used to be able to patch the .m2ts file that TSMuxer.exe creates such that TrueHD works properly, but the author has disabled the TrueHD fix code in the latest ToNMT version. :mad:

The old .jar and cmd file are still available for download here (http://www.mediafire.com/download.php?agdhqjmjenm).

Cool, thanks!

I'll try this for TrueHD muxing ... it should definitely work on the PCH, but I'm more interested in whether it fixes TrueHD for the standalone Sony.

Can't you rerun tsmuxer on the ts file and change the output format to m2ts or even AVCHD?

I can't say it's working properly since my setup isn't quite right but I have done the following.

Muxed a movie into m2ts format (using the latest beta of tsmuxer). Ran multiAVCHD to create a AVCHD folder and copied that to a USB drive.

Had my PS3 audio output set to optical (which all I have at the moment). When the folder is played the audio is audible and noted as Multichannel Dolby or something like that

Then changed the output settings to HDMI. Now I don't get any audio (no HDMI connector to my AVC) but info shows Dolby TrueHD. Of course the sound could be crap - I just can't check at the moment till I get motivated and install my new AVR that can handle MLPCM output.

[idbirch2]

That doesn't really tell us anything new, it's already been established that the PS3 handles the new TSMuxer's TrueHD output just fine. The problem is that stand alone players still seem to be struggling which is making most of us think that TSMuxer still isn't outputting fully compliant TrueHD streams.

Did you get round to testing it SomeJoe?

Haven't been able to yet, but I'll see if I can try it tonight. Gotta dig out the Iron Man BD again ... :)

[SomeJoe]

Was able to try again and test the QuickFix2.cmd -- still no go. Didn't work on the PCH or the standalone.

There's something just fundamentally wrong with what TSMuxer is doing with TrueHD.

At this point, the only thing that's ever worked for me with TrueHD is ToNMT 5.4.3 when playing through the PCH. No other program, method, or playback device combination has properly reproduced a TrueHD stream.

That doesn't really tell us anything new, it's already been established that the PS3 handles the new TSMuxer's TrueHD output just fine. ..

So the PS3 is more tolerant of potential non compliant streams?

Hello All,
Has anyone come across this before ?
I have been using the Scenarist method as highlighted here, Originally Posted by jamos

The PS3 audio is set to pcm, the onscreen display says TrueHD and it sounds as it should.
I now have my Pioneer BDP-95FD on bitstream and the audio is incredibly quiet, to the point where if you turned the amp volume way up there`s still something amiss. If you pause the disc and then press play, for that first split millisecond you can hear the audio trying to come through correctly but then goes incredibly quiet again. I have tried this with the PS3 audio on bitstream and get the same fault so it does seem to be some sort of bitstream issue. Subsequently, I`ve now tried the TSMuxer BD Clown method with their latest versions and still get audio that you can barely hear on bitstream.
Does anyone please have any ideas on this and how I can correct it ?
Thanks very much.
Dave

Are you using the latest TSMuxer (1.8.34 I think)? You certainly shouldn't be having any problems with PS3 playback if you are as TrueHD output was fixed in version 1.8.30. You shouldn't need to bother with Scenarist any more either, give it a try. I've done several TrueHD titles with new the TSMuxer and all have played back fine on my PS3.

Yes, I`ve tried the latest versions.
Do you have your PS3 on bitstream ? If I put my players on internal decoding then they work fine, it`s when I set them to bitstream the problem occurs.

PS3 can't bitsream TrueHD so it's decoding internally. I've had this discussion with a friend at work before, what is the obsession with wanting to see the TrueHD LED light up on your amp? It makes no difference if the audio is decompressed by the player or the amp, the decompressed content is exactly the same. So if it works with the player doing the decoding....let the player do the decoding - hooray, problem solved.
