Vobsubs In MP4

Do you concern about to correct logo the of the vobsub muxed mp4 output?
From the properties tab, it currently shows my x264 video muxed with vobsub as a Nero Main Profile (MPEG4-Part2) media. See
http://www.nero.com/nerodigital/eng/Main_profiles.html.
Where x264 is AVC encoder (MPEG4-Part10) and it should show either of these Nero AVC Profile logo (http://www.nero.com/nerodigital/eng/AVC_profiles.html)

Hi, I found what does 'ndss' mean.
NeroDigital stores brand according content.

ndsm - Nero Digital Mobile
ndsp - Nero Digital Portable
ndss - Nero Digital Standard
ndsc - Nero Digital Cinema
ndsh - Nero Digital HDTV

ndxm - Nero Digital Mobile AVC
ndxp - Nero Digital Portable AVC
ndxs - Nero Digital Standard AVC
ndxc - Nero Digital Cinema AVC
ndxh - Nero Digital HDTV AVC

So mp4box should set proper brand according content or yamb should use -brand and -ab switches of mp4box to add this info.

I wondered how Nero was able to link little certification logo's to their encodes (and provide property info).... I guess this answers it

Hi all,
I built a new version with one bugfix and two features.

download: http://www.cera.cz/gpac/mp4box-20060505.zip

Falco

mp4box - with vobsub support
============================
- Based on current CVS sources of GPAC
- Statically linked with SpiderMonkey 1.5 and zlib 1.2.3
- Supports .idx/.sub VobSub files
- Exporting back to VobSub (idx/sub) is not implemented yet

TODO
====
- Raw export of VobSub track into .idx/.sub
- Setting of correct brand info according content (Nero Digital profiles) - not a VobSub task but nice to have

Version: 0.4.0.3 - 20060505
===========================
- [FEATURE] - possibility to export VobSub track as single track MP4 file and reimport into new MP4 file
- [FEATURE] - delay parameter from .idx file is now processed
- [BUGFIX]  - problems with incorrect colors in Nero ShowTime and MPC fixed

[SeeMoreDigital]

Oh yea.... that's got it... It works well now

EDIT: No problems with MPEG-4 Part 2 or Part 10 YAMB re-muxes, when played in MPC or ShowTime2 player.... Very, very nice work indeed.

Thanks. Either -brand or -ab did the trick! I added "-brand ndxs" in the mux command, it now shows the correct logo.

Falco, you ROCK!!!

Kurt's just made a new version of YAMB to accommodate Nero's "Brands" structuring too!

Does anyone have a link for Kurt's new yamb build?

Why not search for the YAMB thread?

[chipzoller]

oh...didn't know there was one

I have found an anomaly in the VOBsub durations

The Recode2 source shows the following VOBsub durations: -

Track # 6 Info - TrackID 6 - TimeScale 90000 - Duration 00:00:41.040
Media Info: Language "English" - Type "subp" - Sub Type "mp4s" - 16 samples
MPEG-4 Config: Unknown (0x38) Stream - ObjectTypeIndication 0xe0
Synchronized on stream 1

Track # 7 Info - TrackID 7 - TimeScale 90000 - Duration 00:00:50.080
Media Info: Language "English" - Type "subp" - Sub Type "mp4s" - 16 samples
MPEG-4 Config: Unknown (0x38) Stream - ObjectTypeIndication 0xe0
Synchronized on stream 1

But the YAMB/MP4Box re-mux shows these durations: -

Track # 4 Info - TrackID 6 - TimeScale 90000 - Duration 00:00:43.880
Media Info: Language "English" - Type "subp" - Sub Type "mp4s" - 16 samples
MPEG-4 Config: Unknown (0x38) Stream - ObjectTypeIndication 0xe0
Synchronized on stream 3

Track # 5 Info - TrackID 7 - TimeScale 90000 - Duration 00:00:53.360
Media Info: Language "English" - Type "subp" - Sub Type "mp4s" - 16 samples
MPEG-4 Config: Unknown (0x38) Stream - ObjectTypeIndication 0xe0
Synchronized on stream 3

Bummer!

I am curious about the compatibility of the vobsub video created by latest mp4box build by falcon and the Nero certified standalone players.

Did anyone who owns one of the device tried that?

Yes... I've have one person test an encode with 2no AAC audio and 1No VOBsub track and it worked....

I'm going to ask another guy with a different player to test a YAMB re-muxed sample with 2no AAC audio and 2No VOBsub tracks.... And will report back.

That said... the YAMB re-muxed samples VOBsub track are longer than the video track (as reported above) so it might not work!

Seems to be offtopic, but here I can make the quote.

Standalones compatibility:

I have 2 different standalones with MTK chipsets and ND support. With original firmware if inside the resulted MP4 I have ndsc, the file cannot be played because it thinks is Cinema Profile and because this profile support more than 720x576, the firmware have some restriction in it and the file cannot be played. With Recode, Cinema Profile can have 5.1 CH but with Standard Profile only 2 CH. So, what to do if I want to have 5.1 CH on my standalone?
- If I change with Ultraedit for example ndsc into ndss the file can be played. We don't have to worry if the Cinema Profile made by user is with more than 720x576, because if it is, only the audio will be played. But if is under 720x576 we can have 5.1 CH.
- I can modify the ARM Code from the firmware player to ignore the ndsc, but how many users can do that?
- I can search on internet if somebody modified the firmware for my player, but what to do if I want to stay with original firmware or nobody modified it?
- I have the resulted file with ndss inside it.

Because of that I'm thinking about some "option" in YAMB or programs which can make MP4 to save the file with ndss inside it. Is better to have it from the start because maybe in some day the user will have a standalone with ND support or the firmware maker will never exclude the ndsc restriction.
Or, even the resulted MP4 file is with 5.1CH inside it, to have ndss.

On topic: regarding subtitles and standalone compatibility only the subtitles made with Recode can be displayed at this moment. Discussion here. < SMD you can read it and give me also some examples.

enjoy,

There is a switch to remove brand name under MP4Box. So, I can add it into Yamb. But a question remains : when the firmware will be updated to support this, what about utility of this option ?

To avoid more OT, try to reply directly into the Yamb thread...

[Worry]

Hey, Falco, thanks for the marvelous job you've done! I've been waiting for a breakthrough like this for some time and certainly it was not wasted! What I really love is the ability to import VobSub tracks by their IDs and to assign them languages and detailed names in the MP4 container. It's just splendid.
Display of the embedded subtitles is a bit different matter though, because there are so many possible combinations of different tools. I've been using Haali (Matroska) MP4 splitter (no VSfilter) and the VobSub display facility in MPC or ffdshow, mostly without troubles.
However I noticed that ffdshow is processing the subtitles correctly only when MPC's output is directed to Overlay. When VMR7/9 or Haali output is used in MPC, just some textual garbage is displayed. But in this case the MPC's subtitles function works fine. The Haali/ffdshow filter combination works for me even in other applications like the AverTV video player.
But if it wasn't for the small above mentioned glitch (possibly ffdshow problem), I'll just have absolutely nothing to complain about. Really great!

Hi currently, now it is not possible to demux vobsub subpictures from mp4. Currently I'm working on demuxing from mp4 into idx/sub vobsub format.

@cera, will mp4box create MP4 like Nero Recode does with subtitles that can be viewed in standalones? I don't know where are the differences between the output between MP4box and Recode, but only the Recode subtitles can be viewed on standalone. I have standalones with MTK chipsets.

Hi Mtz,
the answer for your question is "Yes". This is a main goal of my patch. Why only subtitles from Recode is displayed on standalones? This is because the subtitles from Recode is not stored in textual form but they are bitmaps like DVD subpictures. The MPEG-4 defines subtitles in textual form but they are not supported by standalones because of missing font rendering engine on them. So Ahead selected the existing format (DVD) of subtitles/subpictures and made the extension to MPEG-4 format that is not standardized. But their subtiles format is a part of Nero Digital and manufacturers of standalones follow it. So it's main goal of my modification of the mp4box because there is no other application than Nero Recode that is capable to create movie in MP4 format with subtitles supported by standalones.
