That's curious, it's unusual that BDInfo would fail to detect these tracks if they were really present. I see that the back of the box screenshot on dvdempire shows that it claims to have these, but did you actually confirm that they are there and accessible when playing the movie?

On the subject of BDInfo, it looks like I have resolved the overestimated bitrate problems with TrueHD. I want to run more tests to make sure everything is copacetic, so I probably won't be posting the new build until tomorrow afternoon at the earliest.

Rambo (IV) has an embedded 720x480 AVC PiP stream that BDInfo doesn't report. Is this by design? Do the bitrates exclude this too?

The way this shows up on the disc is with two separate playlists (actually several separate playlists since there are a few duplicate playlists with the same content, but different MPLS filenames). The main feature playlists are those with length 1:31:31 (M2TS 00112-00125) and the PiP are those with length 2:00:22 (with M2TS 00127-00132 PiP tracks interleaved). I'm not sure if there's a better way to interpret these without a full-blown BD-J implementation.

Code:
Rambo                                           AVC     1:31:31 26,384,185,344# 46,855,015,149  38.44   26.88           DTS-HD Master Audio 7.1
        Rambo PiP (Profile 1.1/seamless hybrid) AVC     2:00:22 31,990,284,288#                 35.44   23.72           DTS-HD Master Audio 7.1

Thanks for double-checking that. I'll have to get a copy of Batman Begins when it comes out in a couple weeks to see what might be going awry. If you are still feeling investigative, you could check the disc with other tools such as eac3to, TSMuxer, TSRemux or BDEdit to see if any of them have any better luck with the detection. I see two main possibilities: a) the Japanese tracks are not present in the playlist file, but are present in the M2TS and its program map, or b) they are present in the playlist, but BDInfo is not parsing them out correctly.

I tried the mpls (00012) in tsmuxer and it sees the jpn audio and subs.

Aren't those additional M2TS files on the longer playlist just the extended branching featurettes? I'm talking about the 720x480 PiP window with a separate PID that none of the playlists include according to BDInfo. Whereas it showed up for National Treasure 2, albeit as an audio track...

I see that the bitrate calculation doesn't include it, at least.

You are absolutely correct sir, my mistake. I'll look into this - life wouldn't be fun if it was perfect...

--- BDInfo v.0.2.3 ---

I went ahead and uploaded BDInfo v.0.2.3. There are a couple of minor tweaks/additions (report now includes BD+ and BD-Java detection), but the main change is a fix to the bitrate calculation for TrueHD and DTS-HD tracks. These seem to be pretty close now as compared to various demuxer outputs and when I apply the new bitrate calculation to CBR audio tracks (such as LPCM or AC3) the numbers come out right which is certainly a good sign. Exact video bitrates are going to be slightly different as well, but for the most part should be confined to less than a 0.01 Mbps difference.

There is also a new section in the output report which gives some stream diagnostics for each scanned M2TS and includes the PID, stream type code, number of bytes/seconds used in the final bitrate calculation and a packet count. This output is enabled by checking the "Include Stream Diagnostics?" box before clicking on View Report. Note that you don't have to tick this box before performing the bitrate scan since the information is collected anyway - it just controls whether or not that section is written into the text report.

One other thing worth noting is that the new TrueHD bitrate number does *not* include the AC3 core - i.e. this is now subtracted out. However, the stream diagnostics section does not perform this separation and reports the combined bitrate of TrueHD + AC3 core if you are interested in comparing the numbers. Also, the TrueHD bit depth (16- vs. 24-bit) is still absolute guesswork, although obviously the thresholds for this have been changed since the TrueHD bitrates are going to be noticeably lower.

Thanks for the update. Do the DTS-HD MA bitrates also exclude the core? We should be comparing apples to apples, I think.

No, the DTS-HD MA tracks still include the core since it actually part of the lossless data - i.e. lossy core + extra data for the lossless extension for DTS-MA vs. lossy core + completely separate lossless data for the TrueHD track. It's actually kind of impressive how much more efficient the stand-alone (minus core) TrueHD appears to be as compared to a comparable DTS-MA track.

Perhaps the DTS extension method results in a noticeable loss of compression efficiency, although tacking a theoretical 1.5Mbps AC3 core onto the TrueHD tracks would certainly change the picture and make them more equivalent. An apples to apples comparison based on bitrate is difficult since they are addressing the same problems in two different ways (i.e. providing a lossless track with an embedded widely supported lossy track, but with a separate lossy track vs. a lossy track that is part of the lossless data).

I haven't played around with FLAC or other lossless codecs much, but it would be interesting to see how they compare in efficiency since the whole "advanced audio codec" thing strikes me as something of a royalty-generating boondoggle. Although, this comes from the perspective of someone who believes that dubs are an abomination for anything but children's programming and 70's Kung Fu, so maybe just a LPCM + AC3/DTS doesn't work when you want to cram on a dozen non-original audio tracks (cough, Warner).

I also did some preliminary poking around today to find out what might be going awry in the Profile 1.1 discs (with some help - thank you!) and I think I see what is going wrong. Hopefully I will be able to put out a new build of BDInfo within the next week to address this as well as including chapter output in the report (and possibly bitrate per chapter if I am feeling lucky).

Please be aware that losslessly compressed tracks can be anywhere between 16bit and 24bit. E.g. it's very easy to use 24bit but keep the lowest 4bits all zeroed out. All the lossless compressors increase compression efficiency with every zeroed out bit. So it's not just 16bit TrueHD vs. 24bit TrueHD. A track can be 18bit or 19bit. I've seen tracks which have bitrates which are near to 16bit, but still when you decode them you get more than 16bit. I think such tracks are probably 18bit or something like that...

FLAC is slightly more efficient than TrueHD, but the difference isn't big.

Oh okay, I thought that TrueHD used the same idea. Makes sense now.

--- BDInfo v.0.3.0 ---

Another day, another version... why the heck not? A shiny new build of BDInfo is now available for download.

The biggest change is bugfixes in the MPLS playlist processing that should resolve a variety of issues with Profile 1.1 discs - i.e. missing PiP video tracks, missing audio/subtitle tracks, PiP tracks being marked as audio tracks or subtitles, etc.

Also, 96kHz DTS-MA tracks should now be identified as such although 7.1 DTS-MA channel counts are still not going to be detected. This information was actually there the whole time in the playlist and I was even processing it, but subsequently overwrote it when I scanned the audio headers - doh!

Finally, I added the list of chapter markers to the output report. I did not get a chance to put in the average video bitrates per chapter yet because this is a little bit more involved than I first thought. This is due to the fact that you can scan multiple MPLS playlists, but each unique M2TS only gets scanned once so it has to deal with the chapter markers from all the playlists that reference it. Not a herculean task, but I figured the MPLS bug fixes were important enough to pushed out sooner rather than later.

Hopefully this build will be good to go for a decent amount of time (hence the optimistic version number bump), barring any new bug-tacular discoveries.

Thanks Cinema Squid for coming up with an updated version of BDInfo.

You said there are plenty of open sources available to develop utilities like BD Info. Any idea on the availability of Java based open sources ? This is because I can come up with a similar tool like you had developed using C# & .Net though I cannot guarantee if it would perform on the same levels as BDInfo on Windows based platform.

Well the bitrate calculation did not change in the short window of time betwen 0.2.3 and 0.3.0, so you should get the same results. Doesn't hurt to scan again to verify this, however.

I'm not aware of any Java-based sources for processing Blu-ray, although they are likely out there. I think the performance would be comparable though for a BDInfo-like tool since it's mostly just file I/O and parsing which C# and Java seem to handle nearly as well (and sometimes better) than C/C++. I guess one of the main disincentives to a cross-platform tool is the lack of a particular "other" tool for alternative OS which is currently critical to the process.

I've seen tracks which have bitrates which are near to 16bit, but still when you decode them you get more than 16bit. I think such tracks are probably 18bit or something like that...

That makes sense and helps explain a lot. I wonder if this dithering process is occuring as a manual step before the encoding process or is done (semi-)automatically by the TrueHD encoding software if the lower-order bits are deemed insignificant. In either case, it seems to stretch the definition of "lossless" a bit since surely those bits aren't all zero in the original 24-bit LPCM source file...

Don't forget that this new bitrate number does not include the AC3 core, so they are going to look lower. Also, as madshi explained above there may be other things going on with truncation of samples under the covers to impact these numbers.

The very same problem was always existing with 16bit lossless/PCM tracks when the studio master is more than 16bit. In all the "I love PCM" threads the majority of people never cared to look at the bitdepth of the Blu-Ray in comparison to the studio master. Anyway, from what I've read all audio experts agree that more than 20bit audio has no benefit whatsoever. There's some kind of disagreement about whether 20bit is better than 16bit or not. Some experts say yes, others say no. But if all experts agree that more than 20bit is useless, I've no problem if studios cut the lower 4bits of the studio master.

Hmmmm... Maybe I should tweak eac3to a bit, so that it reports the exact bitdepth instead of just "16bit" or "more than 16bit". Shouldn't be too hard, I guess...

Yeah I read the change log and agree the results should be the same.

I can get the new version and run it again...

I was just doing it to test my new BD drive in any case

I think that sounds about right since its supposed to be a 20-bit track, a bit lower than the 3000-3500Kbps average we should see for 24-bit tracks now. I bet that most 16bit tracks will fall between 1500-2000Kbps averages now.

Cinema Squid- It now takes only 10-12 minutes to scan a disc on average from the hard drive. In previous versions it would take 20-30 so I am very impressed. Also I have a feature request. Can you add an option to automatically dump the scan report into a .txt file in the same folder as the program once the scan completes. A few times I have finished a scan and then done a reboot or closed it without taking down the info, and I have to do it again.

Updated bitrates:

10,000 BC : Dolby TrueHD 5.1 1666Kbps (48kHz/16-bit)
Spiderwick Chronicles: Dolby TrueHD 5.1 3531Kbps (48kHz/24-bit)

LG 65C6P FW: 05.30.30 | Onkyo TX-RZ730 5.1.4 | Oppo UDP-203 | Sony UBP-X700 | Xbox One X | Chromecast Ultra | Apple TV 4K
LG 55EG9100 | LG 60PK550 | Samsung LN-S4095D | Samsung UBD‑K8500 | Philips BDP7501 | Panasonic DMP-BDT110

That's a good suggestion - I've done that before as well! As far as the speed is concerned, it did seem like it was significantly faster but I hadn't done a direct comparison. I did make some changes to improve performance by tweaking the buffer sizes and chopping out some unused code so I guess it helped.

I have found two bugs in the new version thus far which I've already fixed, but I want to see if anything pops up before posting a new build:

First, the flags indicating BD-J and BD+ detection don't always get cleared between disc scans, so these might be mistakenly reported as present if you scan multiple discs in a row without restarting BDInfo.

Also, in the initial disc scan it occasionally fails to fully parse the audio header information (was not scanning forward to the first sync byte - oops!) so things would be missing from the report like the TrueHD/DTS-HD core information. Out of the 50+ discs that I've rescanned, however, this has only happened on Prison Break and it shouldn't effect the bitrates.

Wow. 40~50% performance improvement is quite impressive. Great work Cinema Squid and thanks for the info. I think the optical lens will now have to do more work in less time.

Blu-ray : 340

Looks like a BD encode to me, PowerDVD and PS3 both reporting peaks in the 34-36 and sometimes even 39 areas.

I don't have the other discs yet, but I will post em over time if no one else does. I just watched a few seconds but the PQ looked very nice, no DNR and a nice grain structure.

Wow. I am amazed at specs of Mad Men: Season 1.

4 hours of content encoded at an average video bit rate of 23 Mbps alongside DTS-HD MA 24-bit which means New Line can do similar stuff with LOTR though they have to cut down on the bits by 1~1.5 Mbps to accommodate 7.1 ch audio.

Blu-ray : 340
