Tag/Headers of Audio in MKVmerge

[sirt]

Hi,

Well I have a nasty issue to tell you about. I've read couple of things about but I can't solve it. Let me explain : in MKVmerge, it is possible to rename track e.g. track name. For example, I've extracter one of my BluRay and I want one of Audio track to be named :

DTS-HD MA Surround 5.1 English

I remux to .mkv, then this name is displayed in VLC Player or MPC : OK.

BUT it is not the case with my BluRay TV player : it keeps displaying something like "Surround 5.1 DTS English" (when I select track with my bd command) e.g. track name set in MKVmerge doesn't seem to matter. It is annoying as if I set two tracks like that in MKVmerge :

DTS-HD MA Surround 5.1 English
DTS Surround 5.1 English

both are displayed as "Surround 5.1 DTS English" when I select them on my TV so I can't distinguish between DTS-HD & DTS.

What can I do ? I want to edit properly audio/video tags. I don't understand why it is not displayed with that name via my BluRay TV player. It seems track names are not taken in account.

Seems than your BluRay TV player is not fully compliant with mkv format, and don't show the track name, it show a incomplete description.

We can't do nothing about this. A workaround is use another language to distinguish between DTS-HD & DTS.

... If your player plays FLAC, you could encode the DTS-MA to that codec and then you'll be able to tell it apart from the regular DTS track.

Other than that, the only other thing you seem to have control over is the language... You could try setting all the DTS-MA (or alternately the regular DTS) tracks to a specific language, then you yourself would be able to tell them apart.

I should think your Blu Ray player interface is all nicely set up to play Blu Rays, and Blu Ray m2ts files don't have track names, they just have codecs and languages, MKV support is just an after-thought.

Well, thank you for your answers but what annoys me is that when I do play the physical BluRay, audio is displayed withmuch more complete information e.g. "DTS-HD MA" is indeed displayed ! I can switch between audio tracks and detailed information is displayed on screen.

From what you say, I understand that this issue is related to mkv format that is not properly recognized by my BluRay player. So mkv standard compliance would be the exact problem. It is annoying as *correct* information exists in original BluRay and is displayed but it is not possible to display it when playing MKV. But how can we be sure this information has *really* been kept ? I initially used MakeMKV to extract/remux my BluRay. Actually it is just a 1-click tool where I can even rename tracks as in MKVmerge (MakeMKV uses MKVmerge anyway to remux so it is the same).

I would not like using another language for these tracks, nor recoding to FLAC (my player doesn't even play FLAC). My concern is not to be able to distinguish tracks by anyway but to display correct information or information I've chosen as it is in BluRay. But I think it is just a mkv compliance issue.

I'm pretty sure m2ts has a separate codec number for DTS-MA, if I remember correctly DTS-Express is the only codec that wasn't given it's own number. In Matroska it's all "A_DTS", so without jumping into the stream headers to read what's there the player has no way of knowing the exact DTS profile that's being used, and apparently doing that is too much to ask for.

[sirt]

Is there a way to remux everything properly to a m2ts then (video, audio, subs) ?

NOTES : actually I think I know : tsMuxerGUI. I cna mux to m2ts there. I don't know whether it is proper or not to do this. Else, there would be much more stuff like "MakeM2TS" or something like that.

I remuxed with TSMuxerGUI into a m2ts but I losse chapters and Audio information is not perfect as well even if it is better. The problem is it seems you can't tag Audio as you wish in tsmuxer.

[ndjamena]

You need to make a Blu Ray folder/ISO/AVCHD. The chapters go in the playlist.

Well thanks but, anyway, I will stick with mkv. Perhaps, a new BluRay player would help to display my own settings. I like having a control on that which is not fully possible with m2ts.
