YAMB 1.6 is out

[bond]

well "stereo" is ok as stereo doesnt mean 2 channels strictly speaking

lemme quote wikipedia:
In technical usage, stereo or stereophony means sound recording and sound reproduction that uses stereographic projection to encode the relative positions of objects and events recorded. A stereo system can include any number of channels, such as the multichannel audio 5.1- and 6.1-channel systems used on high-end film and television productions.maybe calling it "multichannel" would be more user understandable?

[bond]

mp4box doesnt use any phrases for the channelcount

as i said it simply sets "1" for mono and "2" for stereo, as the specs define it

the rest is done by mpc

[SeeMoreDigital]

the rest is done by mpcIn that case... It would make more sense for MP4Box to follow Nero's: "6" for 6 channels policy...


Cheers

[bond]

the specs are clear that there are only two allowed values: 1 and 2

the rest is not spec compliant, whether this is a good thing or not is a different question
for the sake of having a nice display in mpc i wouldnt want the specs to be broken. gabest should simply replace "stereo" with "multichannel" and everything will be fine...

I'm sure users would want to have a clearer indication as to whether the AAC streams within their MP4 encodes contain 2 channels or 6 channels.... I don't think the would want to see something like this: -

http://img132.imageshack.us/img132/7183/yambremuxwith6chand2chaacaudio.png

.... whether it said "stereo" or "multi-channel"...

For all we know, when the "1" an "2" specs were originally drawn up nobody gave any thought for the inclusion of 6Ch (5.1) or even 8Ch (7.1) audio streams!


Cheers

[bond]

yeah, but this doesnt change that the mp4 specs dont cover storing the channelnumber on the container level
is there a field in all the other containers, which tells you the channelnumber of an audio stream? is there the need for this field? is it the job of the container to tell you the channelnumber? obviously MPEG decided that there is no need for such a field...

if you want this to be changed send MPEG a mail ;)

[SeeMoreDigital]

is there a field in all the other containers, which tells you the channelnumber of an audio stream? is there the need for this field? is it the job of the container to tell you the channelnumber? obviously MPEG decided that there is no need for such a field...Well, just to confuse us more.... This is what you see in MPC when you play MPEG-2 VOB files: -

http://img104.imageshack.us/img104/9203/mpeg2vob2ps.jpg

So it would seem, yes there is a field in some of the other "MPEG" containers...

I wonder if the people who write the new MPEG specs refer to previous MPEG specs... for useful information such as this?


Cheers

[Kurtnoise]

is there a field in all the other containers, which tells you the channelnumber of an audio stream?
For Matroska, yes...:)

[SeeMoreDigital]

For Matroska, yes...:)One begs the question... Could you over-ride or provide an option to over-ride the way MP4Box displays this information?

One has to wonder how important is it to conform 100% to "the MPEG specification" in this particular regard?

I wonder too, if anybody has checked to see if an amendment has already been made. Or suggested that an amendment should be made?


Cheers

[Kurtnoise]

Could you over-ride or provide an option to over-ride the way MP4Box displays this information?
For which part ? Extraction or Muxing ?

[SeeMoreDigital]

For which part ? Extraction or Muxing ?Ideally both...

When an 6Ch AAC .AAC stream is muxed into or de-muxed from MP4, the "6Ch" information is lost

Thankfully, when you extract an 6Ch AAC stream from an .MP4 file with YAMB to an MPEG-4 ADTS in .AAC stream it is displayed in MPC as having 6 channels: -

I'll try but I want to test something before...:p

[bond]

what the hell??? dont fuck up what mp4box outputs! you can label in the trackname 6ch as often as you want!

if you change spec compliant files in an incompliant way you will only fuck up things, leave it as it its...

why are people so anal about what mpc reports? if you dont like that mpc reports wrong things than make gabest change mpc and not fuck up your mp4 files in a way that breaks the specs

that said i will make gabest change what mpc reports so that this nonsense ends

May I ask if you are 100% sure that the MPEG-4 spec have not been amended.

May I also ask how allowing for the provision of altering one digit (ie: a "6" instead of a "2"), is going to "fuck up" anything!

I'm all for specifications... but I'm also able to understand that specifications are not 100% accurate from the date they were originally conceived. And like most things in life, they can under-go change.

At the end of the day it's people like us that are using all these applications and tools more than anybody else... I dare say, more so than any of the guys in "white coats" who draw-up these specs.

With this in mind, do you (or anybody else) know how to get in-touch with the creators of these specs so we can put forward our proposed amendments... as a "unified group" of forum members?


Cheers

[bond]

SMD, sorry to say this, but you dont have a clue and also not the will to even get a clue by reading the specs

all you are thinking about is that MPC tells you something that is correct, but you dont like what it tells you. and therefore it should be changed, altough your way to change this would break the specs and therefore potentially fuck up other players than the one you are using
thats imho plain ignorance

you dont have the will to check yourself or even ask other people whether there are ways to get your goal reached without breaking the specs
you dont have the will to ask gabest to change his player in a way it fits what you want.
you dont have the will to ask jeanlf to get mp4box do what you want

instead you go for the easiest way for you and that is to write a post on doom9 and bug kurtnoise to hack your files, altough yamb is obviously the last tool that should be used for what you want to achieve

the channelnumber is stored in the Audio DecoderSpecificInfo "channelConfiguration"

i will ask gabest to readout this for displaying the channelconfig, so smd doesnt need to stress his brain anymore regarding that stereo doesnt mean 2 channels...

With respect, it's not that I do not have "the will" to do this. I don't have the same level of understanding of the specs as you and the necessary resources to obtain "up-to date" versions of the specs (I understand the cost quite a bit).

This is why your services are most important... and why we call upon you to answer such queries!

When armed with the necessary information I will approach (and/or support anyone who approaches) any party who is willing to achieve the target goal.... Which in this case is... getting software media players to display the correct channel information....

Many thanks again for your kind efforts in this regard,

[bond]

well noone has told me how to read specs either, its just that you have to take them, read them, and think about them

after all its not that hard

[stax76]

I recall some mplayer dev writing something like MP4 is very poor, it must be because of things like that, to me it looks reasonable what Nero does.

[SeeMoreDigital]

Your knowledge regarding the MPEG-4 ISO specifications is vast, as is your level of understanding of these specifications... Also, it is well respected, not just on this forum.

[bond]

I recall some mplayer dev writing something like MP4 is very poor, it must be because of things like that, to me it looks reasonable what Nero does.well the number of channels is signalled, so whats the point?
is mp4 a bad container because there is an additional field which tells whether the audio stream is multichannel or not? noone forced gabest or nero to (ab)use this mono/multichannel field for deriving the channel number, obviously its not meant for that...

If the number is stored in some other place what is the point of this field then? mplayer devs and devs like gabest have seen many containers so I trust them more than others. When the specs say 1=mono and 2=stereo then it's very inviting to use 6=5.1. Shouldn't read reasonable specs otherwise 0=mono and 1=multichannel, I'm not well informed regarding containers and crunching bits and bytes so I hope there are more qualified opinions.

Yes, indeed it's fixed...

Many thanks Bond ;)

[bond]

Many thanks Bond ;)yeah, no problem. gabest is a nice guy responding quick to suggestions :p

and you wanted to get kurtnoise to hack the mp4box output for writing incompliant files ;)

[SeeMoreDigital]

and you wanted to get kurtnoise to hack the mp4box output for writing incompliant files ;)Indeed... but that was before you eventually confirmed it was possible to retrive the correct channel number information in another "compliant" way!

You see how much we need you.... this could have gone on for months!

Mind you, I should have mentioned the issue sooner. I first observed it more than a year ago (according to my notes) with mp4UI muxes...

Hi guys,

A new build is out (http://yamb.unite-video.com/Yamb-1.5_20060301.zip) just for testing...

What's new:
- Update MediaInfo.dll (0.7.1.1)
- Timecode for split part supports milliseconds (i.e hh:mm:ss.ccc)
- Add a new Tab dedicated to tags (enable it in Options). I added this because during splitting or joining mp4box remove them. So, now we are able to read/write/remove mp4/m4a tagged files. Mp4tags is of course mandatory to write/remove tags. I'll add AtomicParsley asap. For the reading, I use my own library...;)

Next steps: fix "remove" bug, add chapters viewer/editor (almost finished) and improve extract infos part.

Feel free to test it. :)

btw, as I said in BeLight's thread, development has slown these days coz I'm busy with others things. So, my free time is very limited until April.

[WeaponX]

There's something missing with your MP4Box build of 20060301. When I tried to mux a file, a error message popped up about MP4Box.exe saying libmmd.dll was missing.
The previous MP4Box build did not have that error message.

[Kurtnoise]

erff...right. I forgot to disable icl for this compile. Wait a minute I upload a new build or grab somewhere libmmd.dll (in rarewares.org)

[Kurtnoise]

Redownload it (http://kurtnoise.free.fr/mp4tools/). It should be ok now...

[SeeMoreDigital]

Thanks Kurt... I like it :D

I like the tagger, especially as it can now read the MetaData of existing streams.... By-the-way, the word "Tagger" is not centred in the tab!

With regard to MP4Box in general... I wonder how difficult it would be for Jean to add support for .TS files?


Cheers

[Kurtnoise]

I like it :D
me too...;)


By-the-way, the word "Tagger" is not centred in the tab!
fixed (http://yamb.unite-video.com/Yamb-1.5_20060304.zip)...and you can test also Chapters Viewer/Editor now. :)

With regard to MP4Box in general... I wonder how difficult it would be for Jean to add support for .TS files?
Is it really necessary ? why not using DGIndex first ?

[SeeMoreDigital]

fixed (http://yamb.unite-video.com/Yamb-1.5_20060304.zip)...and you can test also Chapters Viewer/Editor now. :) Marvellous... I will give it a go and report back ;)

[SeeMoreDigital]

Hey... I like the way you've laid out this window: -

http://img108.imageshack.us/img108/2406/yamb18vt.png


I see from this build the way the chapters have to be written/structured as a text file has changed....

Before they could be written/structured like this: -
00:00:00.000 The Beginning
00:00:05.640 Four Wise Men
00:00:09.040 Obi-Wan and Anakin 01
00:00:12.880 Yoda 01
00:00:14.440 Obi-Wan and Anakin 02
00:00:17.360 Mace Windu 01
00:00:18.400 Anakin 01
00:00:20.960 Mace Windu 02
00:00:26.640 Anakin 02
00:00:31.920 Mace Windu 03
00:00:34.600 Yoda 02
00:00:41.040 Obi-Wan and Anakin 03


Now they have to be written/structured (OGM Style) like this: -
CHAPTER01=00:00:00.000
CHAPTER01NAME=The Beginning
CHAPTER02=00:00:05.640
CHAPTER02NAME=Four Wise Men
CHAPTER03=00:00:09.040
CHAPTER03NAME=Obi-Wan and Anakin 01
CHAPTER04=00:00:12.880
CHAPTER04NAME=Yoda 01
CHAPTER05=00:00:14.440
CHAPTER05NAME=Obi-Wan and Anakin 02
CHAPTER06=00:00:17.360
CHAPTER06NAME=Mace Windu 01
CHAPTER07=00:00:18.400
CHAPTER07NAME=Anakin 01
CHAPTER08=00:00:20.960
CHAPTER08NAME=Mace Windu 02
CHAPTER09=00:00:26.640
CHAPTER09NAME=Anakin 02
CHAPTER10=00:00:31.920
CHAPTER10NAME=Mace Windu 03
CHAPTER11=00:00:34.600
CHAPTER11NAME=Yoda 02
CHAPTER12=00:00:41.040
CHAPTER12NAME=Obi-Wan and Anakin 03


I guess it's much easier to input this information into YAMB if you've "grabbed" it from somewhere.... It's more work if you're manually writing the chapters information though.

Great stuff though....

edit: hm i cant get the chapter editor to work
when i open a chapter file i see the normal input options, with "select trackid" aso

edit2: also the "show commandline" option doesnt seem to work anymore

smd, the way the chapter files should look like hasnt changed. the chapter files have always looked like what you posted ("ogm style")
next to those ogm style chapter files mp4box also supports other formats, but all in all it doesnt matter what type you use

[bond]

kurtnoise, thinking about the trackid issue

what about handling things like the gui from mkvmerge:
the user opens one file and yamb displays all streams that are in that file
than the user can easily see whats in the input and enable or disable which stream he wants to have in his output .mp4

Bizarrely, it totally re-writes the original text file, from this: -

00:00:31.920 Mace Windu 03
00:00:34.600 Yoda 02
00:00:41.040 Obi-Wan and Anakin 03


To this: -
CHAPTER01=00 The Begin
CHAPTER01NAME=our Wise Men
CHAPTER02=40 Obi-Wan a
CHAPTER02NAME=oda 01
CHAPTER03=40 Obi-Wan a
CHAPTER03NAME=ace Windu 01

CHAPTER04NAME=ace Windu 02
CHAPTER05=40 Anakin 02
CHAPTER05NAME=ace Windu 03
CHAPTER06=00 Yoda 02
CHAPTER06NAME=bi-Wan and Anakin 03

Why does it try and do this, I wonder?

again, there is no old and new method in mp4box, it still handles chapters exactly the same as before

what you are posting as "the new method" is what was supported since the beginning (eg i always use such files)

i still dont see the commandline :(

there is a problem with chapterfiles looking the following:

CHAPTER1=00:00:00.000
CHAPTER1NAME=Chapter 1the missing "0" between "chapter" and the number seems to trigger yamb to miss the first character after the "=", so there is the first "0" removed and in my example also the "C"

also yamb seems to have problems displaying a chapterfile that is in utf-8

also why does yamb overwrite the chapterfile even if nothing is changed?

about smd's problem: it might happen if yamb doesnt place " " around the path?

Of course, if you create a "b0rked" file, Yamb will have some pbs. With DVDDecrypter or Chapter-X-tractor, you have the correct format.

also yamb seems to have problems displaying a chapterfile that is in utf-8

Why not ? :D I added an option to overwrite or not chapters file.

No, it was my fault and it seems to work fine now. I hope SMD can confirm that...

Of course, if you create a "b0rked" file, Yamb will have some pbs. With DVDDecrypter or Chapter-X-tractor, you have the correct format.thats not a borked file, mp4box handles it fine

also people might want to create these files manually (like i did), eg if you dont use a dvd source

what do you mean ? Try the new one....create a chapterfile formated in utf-8 with special characters, like ö ä ü
yamb will not display those correctly

The OGG style chapters work fine now Kurt.

However, during the muxing process YAMB is creating an enirely new .txt file, identical to the original...
