AC3 in OGM : mux problem - End results ?

[inoteb]

Hey guys, do you read the previous posts sometimes ? ;)

Video+AC3 in Nandub, then in OggMux (where you can add a Vorbis stream if you want, subtitles AND chapters) works flawlessly (no need to use graphedit any more). And believe me, I tested this thoroughly.
The only issues I noticed : audio streams superimposed (except in ZoomPlayer; Blight explained why) and can't hide subtitles.

@ Emp3r0r : Couldn't take a look at your chapter file ("pamameter is incorrect" says my browser :confused: ). But are you sure you put the presets to "Ogg" in ChapterXtractor ? (only available since v.0.961, if my memory is good).
As far as I'm concerned, chapter import (and renaming in french :D ) works great (tested with ZP 2.60, BSPlayer 0.85.486, TCMP 4alpha) : instantaneous jumps as I wrote previously.

Regards,

I'm almost sure I'm doing things correctly... I did read and like I said before, this is what I did:

MUX AVI with AC3 in Nandub
Open that file in OggMux
Import Chapter file created using ChapterXtractor and selecting "OGG"
Mux It

Now the only thing I can think of is maybe my last chapter is screwing things up because I cropped the credits from my movie. If that last chapter points to non-existent point in movie... maybe that caused the crash. I play around with it later tonight and see if I can get it working.

Chapter File link works perfect for me in IE6

Hi.

Just a suggestion.
When you link or post chapter-info files, write the fps of the movie. I mean, the length of the same movie in 23'976 fps and 25 fps is not the same (neither for 29.976 fps :)) The difference between 23.976 and 25 is about 3 minutes (in 25 fps the movie is more or less 1 hour 30 minutes). With 29.976 the difference is greater.

btw, with the bsplayer i have problems with the chapters. When i select a certain chapter, the movie goes some seconds after this point, Why? I think it has to do with the first keyframe that is found after the time of the chapter. What can i do to fix this. :confused: (NOTE: I wrote the times by my own in oggmux, not with ChapterXtractor nor SmartRipper).

thanx

@ Emp3r0r :
Well, I haven't been at home for three days and the PC I use at work is crap with an old version of Natscape; maybe that's why I couldn't catch your link; I'll retry when I'll get back home (Wednesday evening), but I think you could be on the right way looking at your last chapter... tell me about it.

@ Palikrovol :
Take a look at the properties of the Ogg filters (I can't remember witch one... and can't check it as I'm not at home :( ; maybe the Ogg splitter/muxer ?). It seems to me there's an option to set seeking keyframe accurate or not.

Cya!

If I remeber my tests in this direction correctly, this wont really help. You'll just have several seconds balckness till the next keyframe (where you would have jumped). Only thing that would really help is (afaik):

- either correct chapter times to the previous keyframe
- or force keyframes on chapters on encode

or force keyframes on chapters on encode
I've thought of this before but was always too lazy to modify the stats file to make it happen. maybe somebody should mention this to theWef or the XVID crew... i really think we need an easy way to make sure there is a keyframe at the start of each chapter. This is an important issue in my opinion especially since players like ZoomPlayer 2.7 will offer better OGM chapter support. Anybody already doing this with their encodes?

When you link or post chapter-info files, write the fps of the movie.
I didn't know anyone was wanting to use the file but if you are it is for region 1 NTSC. I have began work on an online chapter database, but it would only work out if other people besides just me submitted chapter information. I'll get it online and see what happens.

I really don't want to use this one (maybe others if posted :)). But my post was for general interest about this kind of things ,also concerning subtitles. Some of the subtitles i get (www.divxsubtitles.net & www.subtitles.cz) have no fps note, so i have to make some maths :) to figure it out and translate it to the correct fps for my movie (using some tools too :)).
The real point is that is very easy to put the file info in its name ;) (and it is very useful for many others)

Tobias was seen lately, he was chatting with Blacksun on ICQ, maybe Blacksun can tell us what latest situation is and if Tobias will continue his work on Ogg container format or not !

This post is a bit old but the work on OGG is continuing and we have some cool projects for it :)

I kinda am, just one chapter for my tv captured anime eps to skip the op. But theres not much tweaking involved, since the first frame after the op so far always has been a automatic keyframe due to scene change (surprise surprise).

Cheers

P.S: The first (known to me) fansubbed anime ep released in OGM also has chapters.

this has been driving me crazy and I have come to the conclusion that...Video+AC3 in Nandub, then in OggMux (where you can add a Vorbis stream if you want, subtitles AND chapters) works flawlessly (no need to use graphedit any more). And believe me, I tested this thoroughly. ...is not valid for me. I can only create crashproof OGM's by using graphedit. So I'm not sure what I'm doing wrong if anything but the graphedit muxed files are fine and the OggMux files are crashing. I just wish I could add chapters with graphedit somehow... is this possible?

ok, my brother walks in and tells me the Matix backup I did isn't working either, and I just had a breakthrough... let me gather my thoughts and I'll explain

[Emp3r0r]

here is my breakthrough:

Divx5 + AC3 + OGM + ddfshow filter = crash
Divx5 + AC3 + OGM + Divx filter = ok
Divx5 + AC3 + AVI + ddfshow filter = ok

I realized this after I discovered it had to have something to do with Divx5 because with Xvid and Divx4, things seem to be working fine. (keep in mind haven't tested all the possibilites) I then narrowed it down to the ddfshow filter as the source of the problem. After a switch to the regular Divx decoder filter I successfully got Divx5 + AC3 + OGM + Chapters working! Finally :D

[inoteb]

@ BlackSun : Great news :D

@ Emp3r0r :
Congratulations for your success !
For information, to add chapters in Graphedit, right click on "Ogg Multiplexer" > "Properties...", select video stream (most often "stream 0") and copy/paste the data from your ChapterXtractor file to the fields (click "Set" each time). See attached image for a snapshot.
And while you're there, you can also modify the name of the audio streams (set "Commentary" instead of "English", or "Français" instead of "French" for instance ;) , things you can't do for the moment with OggMux, unfortunately)

Cya!

@inoteb: i see no attached image and thanks for all your help in advancing the quality of my OGM files.

a forum moderator has to aprove the attachement before it will apear

[inoteb]

Hey guyz, I made a few tests with ZoomPlayer 2.7b1 and it works GREAT with OggMedia :D
-audio stream change : OK (even with DivX+AC3 muxed in NanDub then muxed with Ogg in OggMux : no need to use "Audio track" section anymore; the OGM menu of "Language" section works flawlessly)
-display/hide subtitles (SRT in OggMux) : OK
-chapters jumps : OK (as in 2.60)
+ 2 new buttons on the skin to select next audio/subtitle track (and they work !)

Well, with this new version it's clear to me that for the moment, ZoomPlayer is the best player for OggMedia. I do hope that BlackSun and his team will take up the challenge. TCMP4 claims to be the official OggMedia player, yes or no ? ;)

Cya!

@ Christian
Glad to "see" you again.
1 month ago I posted a small "bug report" regarding OggMedia on TCMP beta testers' forum, but I'm still waiting for a reply... :(
http://www.powerdivx.com/phpbb2/viewtopic.php?t=563
I would have been so happy to get just a small reply like "OK, don't worry, we'll take care of that" or even "sorry, we have more important things to do"...

BTW, do you know if Tobias is still working on his Ogg & Subtitles DS filters ? And can we expect new releases soon (hopefully fixing bugs with AC3 muxing & subtitles display)?

Regards,
inoteb ;-]

PS - I didn't try alpha25 yet. Will do that next week...

OK, dont worry, we`ll take care of that :D ... no seriously, every bug report in the betstest section is precious and will be respected ( we even have a compiled bug list ), but for the time being there are really more important things to be done to be able to launch the player as a public beta.
The Core Mediaplayer is and shall be the 'official' .ogm player, Blacksun is in direct contact with Tobias and you can be sure both will work prefectly together.
BTW, do you know if Tobias is still working on his Ogg & Subtitles DS filters ? And can we expect new releases soon (hopefully fixing bugs with AC3 muxing & subtitles display)?
Unfortunately i couldnt talk to Tobias myself during the last months, but i know Blacksun is talking to him from time to time, and he told me Tobias still has big plans with his Ogg implementation, but only very limited time for now.
PS - I didn't try alpha25 yet. Will do that next week... ... off you go testing and posting a bug report ;) !!

thanx

PAL encoded movies are 25fps
Movies in theaters are 24fps
To convert it to DVD from 24 to 25fps, they simply speed up the film, displaying 25fps instead of the normal 24.
It results in a movie lasting 96% of the original time.
NTSC encoded movies are not subjects to this.
BTW, conversions are needed for chapters and subtitles between NTSC and PAL.

@ Christian
Thanx for the reply. I can go on vacation (almost 2 months!:D :D :D ) totally relax and free of worries :cool:
Just few things to do before leaving (testing alpha25 for instance, and may be posting a bug report ;) ) and then : a long summer of PC detoxication :scared: !

Cya in September,

is there any proper and accurate way of doing this? I have no PAL movies to test with.
