BD Rebuilder Beta - Bug Reports Only

[setarip_old]

@jdobbs

Original Blu-ray disc shows secondary video as "Profile HIGH 3.2", while BD-RB conversion shows secondary video as "Profile MAIN 3.2".

Does this have any bearing on playback of PIP/DTS Express?

For DTS Express testing on my SONY 360:

Just completed a 25Gb (BD-R, to make certain no disparity vis-a-vis BD-RE) backup of "Source Code". Results were similar to those noted by Capsbackup. Secondary video appeared and behaved properly, but was silent. From what I was able to discern, the primary audio was not diminished at all.

Just to "keep 'em honest", I also made a "BD9". The results were as disappointing as I expected (based on past results with other PIP Blu-rays (NOT DTS Express) - no audio whatsoever (Not even available with the remote) and empty PIP frames.

I don't know if it matters but DTSXTEMP.avs is buggy, "frames" is not a argument for BlankClip.

BlankClip(frames=6,fps=23.976, stereo=true, audio_rate=48000)

The correct one should be:

BlankClip(length=6,fps=23.976, stereo=true, audio_rate=48000)

Otherwise dummy AC3 is mono 32ms instead of stereo 250ms.

No, it wouldn't. Likely the only difference is that some feature unique to HIGH profile (4x4 transform maybe?) was used in the original that wasn't in the backup.

Yeah, I'm working on that one. The playlist's first M2TS has video that is longer than its audio -- but has the same start time. I have to modify BD-RB so that it adjusts for that possiblity when the multipart playlist has a connection_condition that doesn't require sync between the parts. This is the first disc I've ever seen where that is the case.

Ok. I'll take a look at that. But it really doesn't matter. It's just creating a placeholder there that will be updated to match the DTS Express profile after it is reintegrated. I'm probably going to change the way that works at some point anyway. But that was a good catch.

Ran a Full Backup of Stand By Me (EU, Sony) using High-Speed BD25 option (2 passes). It finished a few minutes ago, and I ran the first playback test using a Dune HD Max directly off the encoding PC's shared directory over CIFS/SMB. I first set Dune's audio Setup to allow PiP mixing, and the Full Backup appears to be working perfectly; both the PiP image and its DTS Express audio play fine. I'll burn the backup on a BD-RE next and start testing it in stand-alone players.

edit: Something interesting happened on the PS3 (old Fatty one, disconnected from the 'net). Note: this might have something to do with me using a BD-RE disc.

I started the movie by selecting PiP commentary in Special Features Menu. When this feature is selected, disc plays a brief video clip of the meeting of the director and a couple of actors, followed by the actual movie. Now, PiP video and audio are both already active during the clip but contain nothing (same on the original disc) so only main video and audio are playing. When movie starts, PiP window pops up at the 10 second mark approximately.

On the PS3, playback was interrupted at approx. 1 minute into the video clip with a message "This Disc is Invalid". I returned to PS3 XMB and restarted the disc, selected PiP commentary under Special Features and used the Next Chapter button to skip the video clip to start the actual movie. Again, after approx. 1 minute playback is interrupted with the "Disc is invalid" error message.

Same thing happens on the newer PS3 Slim.

edit: No problems on a Sony S470, PiP worked beautifully. Ditto on an LG BX580 (surprise, because it's a piece of crap player).

edit: It's a no go on an Oppo BDP-83. Loads Main Menu but once PiP is selected and the video clip is supposed to start, player gets stuck at 0:00:06.

edit: First attempt on a Philips 9500 resulted in PiP video playing OK but audio was from movie. Went to player settings and switched HDMI audio to AUTO, restarted disc playback, and both PiP video and audio play fine.

Just completed and burned a 25Gb Full Disc backup of "Band of Brothers" Disc 1 Episodes 1 and 2. Each episode contains TWO DTS Express audiostreams - one for an interactive "field guide" (including some PIP movies and video) and the other for PIP (with video inserts) commentary by the real life heroes of this series.

Playback on SONY 360 yielded results identical to my earlier test using "Source Code" - each of the two types of secondary video (inserts) displayed properly, but without any secondary audio. Primary audio continued to play with no noticeable volume reduction.

[jdobbs]

Interesting... from the reports I've seen so far it is only the Sony players that previously had issues with PiP on DVD-9 that are seeing issues with the reintegrated DTS Express now. It's gotta' be some minor difference. Unfortunately I've been comparing the original and the copy and that difference hasn't shown itself yet.

Hopefully someone else out there will try it on a PS3 so we can judge better whether it is the BD-RE that is the issue or something in the muxing.

I've completed two Universal titles, The Mummy and The Thing, to bd-25. I've tried them on a Sony, LG, Samsung and Panasonic. The only one which played the PiP with audio was the Panasonic. All played okay, and produced the PiP window at the correct time. I'm now trying non-Universal titles.

I will try other models but to date:
Sony 360 / LG BD370 / Samsung C6500 + D8500 / Panasonic BS-750

Can you tell me the model #'s of the players?

Ran a Very Fast 1-pass (ABR) Full Backup of Risky Business (EU). Secondary audio is Dolby Digital Plus instead of DTS Express, actually.

Something appears to have gone wrong with Seconday video (PiP video stream). While the PiP window opens properly, the video is quite riddled with artefacts during horizontal movement. Here's the relevant bit from bd-rebuilder.log:

[19:31:23] PHASE ONE, Encoding
- [19:31:23] Processing: VID_00002 (1 of 6)
- [19:31:23] Extracting A/V streams [VID_00002]
- [19:41:55] Reencoding video [VID_00002]
- [19:41:55] Reencoding secondary video [TRK_02]
- Source Video: VC-1, 1920x1080
- Rate/Length: 23,976fps, 142 633 frames
- Bitrate: 16 944 Kbs
- [19:48:51] Reencoding: VID_00002, Pass 1 of 1
- [21:08:20] Video Encode complete

Re-checked original: no such artefacts in Secondary video.

I'll run another encode of this using high quality settings tonight and will burn it on a BD-R tomorrow. I'm pretty sure PS3 issues are caused by BD-RE.

Did you make sure the audio settings of all players were set for PiP audio?

No - it was a bit rushed when I got in this evening. I will check again later.

[Ch3vr0n]

For Anyone out there using a Panasonic DMP-BD85 or similar device. Below are my settings. In the setup menu go to audio. The top 3 options are in my case set to "bitstream" and the bottom option below the long text "BD Video Secondairy Audio" i think it is labelled, set to "on". My PiP's work flawlessly with those settings.

[SquallMX]

Tested Ridley Scott's Robin Hood Latin America Blu-ray (PiP and Multiangle):

• TotalMedia Theater 5 plays everything OK
• PowerDVD 11 don't play the PiP Audio
• PlayStation 3 plays PiP audio and video but with occasional hiccups, and skips the first 2-3 seconds of each M2TS with PiP causing temporal freezing even during normal viewing
• Media Player Classic Home Cinema can not render the M2TS files
• BDInfo reports the M2TS files with PiP as corrupted or encrypted

Even in this alpha stage is more compatible than DVDFab solution .

[drmih]

I'm not sure if there is anything to learn, but I have done The Mummy with the latest version and DVDFab. With BD-Rebuilder, on all bar the Panasonic so far, I don't get the secondary audio, but DVDFab has always got the audio correct but never shows the PiP. Therefore is there something which can be compared between the two to look for differences?

ps Off topic a bit but the copy done with BD-RB suffers from lots of motion glitches / blocks of pixels even though bd-25.
