Vobsubs In MP4 [Archive]

Since today, there is someone...;)

Ivan Vecera (aka Falco) has posted on gpac website (http://sourceforge.net/tracker/index.php?func=detail&aid=1477731&group_id=84101&atid=571740) a patch to have the possibility to mux vobsub file with MP4Box.

Hi all, sorry for delay. Now I have a patch for gpac,
that allows import VobSub subtitles. This is private
extension of Nero Digital format.

Limitations:
- Only VobSub (.idx/.sub) format supported
- VobSub features such as align, scale, alpha... stored
in .idx file are not supported

I've made some tests with his compile on my Windows box :
Mux works fine with only one track.
Playback doesn't work with Nero Showtime (i.e subs are found but don't appear).
Subs streams work with Haali Splitter and Gabest Splitter but appear in green. (Hint: VSFilter must be disable)
We can mux several subs but splitters are not able to switch each others.

Not bad for a first attempt.

btw, thanks to SMD for the tips. ;)

Some extra tests this morning...It seems that VSFilter doesn't like this kind of streams. So, I disable it and playback works fine with both Haali & Gabest splitters. However, they are rendered in green color...Strange. Does anybody else have made some tests ?

I'm updating YAMB to include this trick.

How cool is that? :D

I wanted to try some tests, but I'm such a clueless n00b that I couldn't even figure out what to do with the "gpac-vobsub.patch" file to implement this. :p

Yamb is a great frontend, BTW!

Just done some quick tests with Kurt's new builds of YAMB and MP4box...

So far I've been unable to get Media Player Classic to display the VOBsubs.... MPC knows they are there because it lists them under subtitles and properties!

No such troubles with VLC player however, the subtitles are displayed fine.

This is a great start :D

Hey great...

It's possible to de-mux VOBsubs streams and save them within the .MP4 container and re-mux them again... Even re-name them ;)

Slightly different results for me:

Subs do show up in Nero Showtime and MPC but they appear in bloated green.

Subs appear perfectly in VLC, but for some reason the chapters don't work, perhaps mp4 chapters feature isn't implemented in VLC?

Still, very exciting progress!

I'm finding it difficult to get my head around why I'm unable to see the subtitles in MediaPlayer Classic.

If I play this (http://homepage.ntlworld.com/seemoredigital/Temp_Test_Files/Recode2_Source.7z) Recode2 source, I can see the VOBsub subtitles perfectly. However, if I load the Recode2 source into YAMB and hit "Mux", I'm unable to see the VOBsub subtitles in the YAMB re-mux!

Effectively, the only difference I can see between the files is this.....

Recode2 source: -
* Movie Info *
Timescale 1000 - Duration 00:00:50.800
Fragmented File no - 6 track(s)
File Brand avc1 - version 0

Quick answer : Nero Recode and MP4Box don't use the same muxer. So, you don't have the same infos.

Yesterday I installed Nero 7.2.0.3b on another PC and hope to experiment with it's new "subtitle" import and conversion utility. If it converts .SRT, .SUB and .TXT over to VOBsub style subtitles, I think it would be interesting to know how it does this!

The Scene Profile Level tell the player which BIFS nodes,commands and ROUTES he have to know to be able to render the SceneDescription.

The Graphic Profile Level tell you which graphics and textual elements can be used in the scene.

The Object Descriptor Profile tell you which OD and SL tools the player have to support.

0xFE = no profile specified (there is no profile in the standard that match the used tools)
0xFF =no capability required

Okay boys and girls....

Over on my other PC (a £299.00 DELL with crummy on-board Intel graphics but 19" LCD monitor) I installed Haali/Matroska Splitter (Dated: 25-02-2006).

Using Media Player Classic with VMR7 Renderless and with the internal MP4 source filter disabled... When I play the YAMB re-mux, I now see perfect looking and coloured subtitles, identical to the Recode2 source :)

I suspect Gabest's MP4 source filter requires a little tweak...

I've yet to see any subtitles of any kind using the special build of mp4box and yamb. I get no error when muxing the stream in, but I see nothing when played back using mplayerclassic or vlc.

You guys doing anything special?

Kurtnoise

1st May 2006, 21:31

You guys doing anything special?
depends...what kind of streams did you add with your subtitles ?

@SMD : you remux the vobsub file (embedded in mp4) with other streams or you mux directly each streams (i.e avc/aac/idx) ?

SMD : you remux the vobsub file (embedded in mp4) with other streams or you mux directly each streams (i.e avc/aac/idx) ?With the video, I mux the MPEG-4 AVC or SP/ASP streams either RAW or in .MP4.
With the audio, I mux the AAC streams either as .AAC or in .MP4
And with the VOBsubs, as you say, they are de-muxed with YAMB and stored within .MP4

I was just testing the functionality by muxing vobstream with just the video. Doesn't seem to work on my end.

Well after doing some tests with the special build of mp4box/yamb, I've found (VSfilter is not installed on vobsub) that the resulting file (only muxed vobsubs in later to a video/audio stream mp4) only plays with subs (they're green) in nero showtime and not MPC, VLC or with haali splitter (even though it does recognize there are subs present).

Any ideas?

What vobsub files do you use? Are they originals ripped from DVD or generated? I tried some streams generated from txt2vobsub and no subtitles were displayed, maybe a bug in this program. With original subpictures ripped from DVD I have any problems.
As for green subpictures I see that the problem is in palette stored in .idx file and I also found one bug in Gabest MP4 splitter (for more information please go to: http://sourceforge.net/tracker/index.php?func=detail&aid=1477731&group_id=84101&atid=571740)

So far all my subtitle experiments have been with re-using the original Recode2 VOBsubs...

But like I mentioned before, the VOBsubs don't appear in Media Player Classic (using the internal MP4 source filter).

On my other PC which currently only has latest version of Nero 7 installed, Showtime 2 player with not display the subs either. It knows they are there because it lists them under properties but will not lock onto them after being selected :confused:

3rd May 2006, 21:58

I just did a test on one subtitle stream where the subs did not appear green but retained the original formatting. They play back fine if I set Haali's splitter to autoload VSFilter.

Yeah, Haali displays mine as a light blue (original yellow) but internal w/ mpc and nero showtime display correctly. Gabest's splitter seems to work fine.

For some reason VLC not only displays them larger, but a different color and aligned incorrectly on the screen.

cera

4th May 2006, 15:30

Indeed...Now, it works like a charm with the last Nero ShowTime and the MP4 Splitter from Gabest. Good job Falco. :)

There is still an issue with Haali Splitter though. (subs are rendered in black for me)

This is problem because Haali Splitter is not opensource and I cannot look for this issue.

What's currently missing is exporting tracks from MP4. But now I'm working on it.

Falco

Falco,

Would we eventually be able to demux the subtitle stream (assuming vobsub format) back into a vobsub format that still has the original formatting/layout?

If you are interested by demux/remux trick, here is a solution : your mp4 source --> remux into mkv --> extract vobsub file --> remux idx/sub into a new mp4. :)Hi Kurt,

I would like to try that but I don't have any MKV tools (discounting AVI-Mux GUI) installed in my PC... Could e-mail me the de-muxed idx/sub track from my Recode2 source so I can experiment please?

Yes, I'm working on it now. What do you think about formatting and layout? VobSub format stores subpictures as RLE encoded bitmaps, so formatting cannot be changed.

5th May 2006, 07:28

@Falco,
Thanks a lot. It seems to fix a lots with the new build (20060504). My nero ShowTime shows the colour correctly. A previously unplayable clip (mux with previous build) is playable with ShowTime now by re-muxing with the new build!! -> Bug fixed? Good!

And I also noted that the output mp4 file with Vobsub muxed is displaying a "nero" icon rather than a normal mp4 icon. :)

The icon is displayed because in the new version of mp4box is added additional brand "NDSS". I don't know what does it mean (probably NeroDigitalSystemStream or NeroDigitalSubpictureStream) but Nero Recode adds this brand into its files.

Can any else confirm :o

I tested your stream in ShowTime and also in Media Player Classic 6.4.9.0 with ffdshow-20051129 to decode H.264 and with Video Mixing Renderer 9 (renderless) enabled. There were no problems. Maybe you have some problems with your configuration of MPC.

Cheers

Yes, I see...
And I know why... that's because mp4box strips "track layout info". This is important information because it says the resolution of display for the subpictures track (eg. 720x576, 720x480...)
I tried to extract subpicture track as MP4 file with one single track and then mux the track from this MP4 file into another and "track layout info was lost".
I will update my patch... please wait for next release.

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.

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

ndss - Nero Digital Standard
ndsc - Nero Digital Cinema

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. (http://forum.doom9.org/showthread.php?p=824829#post824829) < SMD you can read it and give me also some examples.

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...

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!

@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.

enjoy,
Mtz

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.

If they had done, there wouldn't have been any need to have all these different subtitle formats :eek:

This doesn't have much to do with vobsubs in mp4...but I'm wondering in adjusting them before muxing in mp4. If you needed a global delay of a certain period (i.e. all sub time codes adjusted by amount X) do you use 'time offset' or 'delay'? My understanding is that 'delay' is used for individual time codes, but I'm not sure.

thanks for any help

mellon

29th May 2006, 14:35

One can use a separate "delay" for every track specified in the .IDX file. All entries (timecodes) of this track will be shifted by the specified amount after the occurence of "delay".

chipzoller

29th May 2006, 14:47

Something like this?:

# English
id: en, index: 0
delay: -00:01:21:900
# Decomment next line to activate alternative name in DirectVobSub / Windows Media Player 6.x
# alt: English
# Vob/Cell ID: 1, 17 (PTS: 4245465)
timestamp: 01:12:59:208, filepos: 000000000

First of all, the mp4box vobsub import seems to work perfectly, thanks.

Then, a question:

Any tools for extracting and stripping the vobsubs from mp4?

I just muxed some vobsubs into the container, realizing later that they were much too long with respect to the av tracks. As a result, players like mpc and vlc fail drastically in the end of this file. And now the original vobsub-files are gone, and I'd like to fix the problem... Any suggestions?

Hi all,
sorry for delay, I have too much work in a company. But I have one good message. Today I finally implemented vobsub extraction. I sent appropriate patch to Jean, he will integrate it into CVS. I tested the extraction and works well for me. The extraction has one small limitation. It is possible to extract only one track into .idx/.sub file. In other words if you extract more than one track, every will have own .idx/.sub file. For impatient people I have built a binary for Win32. You can download it as usual:
