Edited that same movie and only had a setstream command before the play pl command in movie object 0 and the movie both plays correctly and set the subtitle on that I specified.

That's strange... I know I've done this a long time ago (before I started removing almost everything keeping only setstream and play pl...)... But I can't remember if it was on tsmuxer's index.bdmv/MovieObject.bdmv or Adobe Encore CS4... I'll make a few tests and will keep you informed...

In multiAVCHD I use only one setstream in the whole compilation and it is before calling title#0 (top menu).

Hi !

I have problems with VC1 video streams (remuxed through TSMuxer) when playing on my Panasonic BD 35. Is there a trick to fix this trouble please ? Thanks !

[laserfan]

Just noticed this on the AnyDVD forum:

Fix (Blu-ray): Playback issues with Panasonic Blu-ray players

This is in the latest version--I have never noticed any comments there about Panny problems, but one wonders if it might have anything to do with problems being discussed here!?

[turbojet]

It has to do with removing region in anydvd.

What kind of problems ? Burning BD-25/50 or BD5/9 ?
At least, be aware that VC1 is not AVCHD compliant. So that might be a reason why VC1 streams don't work on BD5/BD9.

@alc0re

I still have this on my to do list... lacking time...

I am not 100% sure I interpret navigation commands correctly, but based on what i see in the outputs from tsmuxer and Adobe Encore CS4, I tried a slightly different scenario to get audio/subs on by default...

The short version:

Use "Play PL_MK 0, 0" instead of "Play PL 0" in my previous procedure


The long version:

Use BDEdit to remove all movie objects but one, keep only 2 nav commands, and update them as follows:
- SetStream 2147598337, 0 [Forcing 1st audio and 1st sub]
- Play PL_MK 0, 0 [Playing Playlist #0 ????]
In addition:
- Assign movie object #0 to "First Playback" and "Top Menu"
- Choose "Movie" as the type of movie object for "First Playback"

Tried this only once so far... works fine... and the LCD displays the play time...

@alc0re, a little feedback would be appreciated

Play PL X - Plays playlist file X (i.e. X=1 - 00001.mpls) from first playitem ignoring previous chapter/playitem settings
Play PL PI 0, 1 - Plays second (1) playitem from playlist 0 (00000.mpls)
Play PL MK X, Y - Plays specific chapter from a title.

Thanks for clarifying this.

Any idea why "Play PL 0" indeed plays playlist but doesn't *show* the play time on the LCD of the BD35 ????

[deank]

I guess because your player shows info only when playing a normal title with duration and chapter information set by navigational commands. I think Play PL is not to be used for playing normal titles, but for menu extras like warnings or menu pages (like I use it). Also what is allowed for display and operate is set with other means in playlist files (as you see in middle-upper part of playlist BDedit window).

[MadMonkey57]

OK. I understand the differences between PL and PL_MK and therefore why PL_MK is appropriate here.

What I see in the outputs of tsmuxer and Encore is GPR assignments, comparisons, and title jumps. In both cases, if I walk trough the code, I always end up PLAY PL_MK 0, 0

I was assuming this: Nero Vision and Encore insert these GPR assignments and other nav commands within a generic authoring process. In the case of a main movie only, if all we need is starting the disc at the 1st chapter, manipulating those GPRs is useless.

My question is: what manipulating GPRs has to do with the SAP "learning" info from the disc like duration and so on ?? I though this kind of info was stored in PSRs.

EDIT: IMO, PLAY PL_MK nav command triggers the SAP to load some data in the PSRs. I guess it's not the case with PLAY PL.

[deank]

Yes, PSRs hold player status but those cannot be changed - only read, thus menu pages or m2ts files with program codes parse information to movieobject and title#0 (top menu) via GPRs.

For example your player is showing a menu page. The menu page itself contains move/compare... nav commands changing GPRs and then your top menu knows what title/chapter to play, which audio or subtitle stream to enable or disable, etc...

In case of no menu and no need to know what menu page is shown or what user actions are performed you can use Immediate values (of course if the nav command accepts such - as you know some commands require target to be a register).

Also some GPRs get changed by the player itself (while executing playlists), reflecting current chapter/title ie....

GPRs are also mostly used for sort of 'communication' between titles and their program codes (movieobject object IDs).

Also for easy reading one can think of Play commands as:

Play PL X = Play PLaylist X (XXXXX.mpls)
Play PL MK X, Y= Play PLaylist X, starting from playlist MarK (chapter) Y (so this version of the command is time-based)
Play PL PI X, Y = Play PLaylist X, starting from Play Item Y (if your mpls contains references to more than 1 m2ts file - each m2ts is a playitem) - so in other words it means - check playlist xxxxx.mpls and play (Y-1)th m2ts file from it (this version is more like file based) PlayItems are zeropadded so the first is 0, tenth is 9, etc... Of course this is really simplified explanation... but I guess you get the idea.

***

It is not a good idea to have Title#0 (top menu) and Title#1 (main movie) to share the same objectID. While playing a title as TOP menu - navigation is handled differently and information displayed on SAPs LCD or TV is different, too. The best way is to have a simple Jump title #1 for top menu, Play PL MK 0,0 in title#1 (if your mpls file is 00000.mpls), BREAK to quit playback.

OK. This is obviously what was troubling me... I would never have thought that the player would alter GPRs... Do you have any info (link ?) on this ? What GPRs can be altered ? What is the trigger ? What is the meaning of the value ?

Thanks for this explanation.

Could you be a little more specific about that ?

This minimalistic BD structure / nav commands looks VERY nice, and very close to what tsmuxer and Encore produce (better BD compliancy), stripped out of every unnecessary GPRs manipulations... I definitely will try this for my next backup. Thanks a lot deank.

Now again about registers.

It turned out that some PSRs are Player STATUS Registers and some are Player SETTING Registers.

Some STATUS registers can be changed with navigational commands and none of the SETTING registers can be changed (except with some workarounds when using BD-J applications).

And for example changing the value in PSR11 should make the player switch to/display another menu page....

May be not knowing this confused me that the player can alter GPRs, but in fact - depending on player's firmware - it is allowed to set/change GPRs, for example on start-up/disc-loading/changing settings in player's menu, etc...

Let me know if I can be of further assistance.

Has anyone tried tsMuxer Version 1.8.35(b)? The reason I ask is because I'm finding that it does not work with my BD-35. The player give error "unsupported" disc.

[alc0re]

I have yet to try it, but there's two modes now. According to the release notes, if you're buring to a dvd you need to use avchd mode, not bluray mode. bluray mode is only for burning to actual bluray discs. Not sure if that's the issue you're having or not though.

EDIT : Just tried it. Confirmed that tsMuxer 1.8.35(b) works just fine with a bd-35 as long as you choose avchd mode.

Ohh, that's why. I chose blu-ray. Any idea why blu-ray output doesn't work?
