help how to get subtitle from rmvb format

[simonrule]

hello
can any one help me on how ican get subtitle from rmvb

[Ai Haibara]

I don't think the RMVB container allows for subtitle streams, so the subs are probably burned into the video - meaning you'll have to OCR these subtitles as well. Two problems, though:

1) I'm not sure any of the OCR programs accepts RMVBs.
2) Even if they do accept RMVBs, Real formats tend to be highly compressed, and that might make OCRing the subs even more of a chore.

You're still better off trying to find the subtitles through a web or subtitle search engine search.

But oh, yes, the RM(VB) container does support embedded subtitles.
There exists a free tool (rmsubmux) for adding text subtitles to RM files,
however I don't know if RealProducer is capable of extracting them.
Maybe you can remux the original .RM into a .MKV with mkvmerge,
and later extract the subtitle stream with mkvextract.

HTH.

That assumes that

a) The subtitles are in fact embedded and not hard subs (facts not in evidence at this time, your honour),

and b) MKVMerge will read embedded subs from am RM file when converting it into an MKV file (something I admittedly have not attempted because I don't bother with the RM format)

@ guns1inger:

Thanks for the pertinent comments. Sadly you're right,
mkvmerge doesn't detect the embedded subtitles in RealMedia files.

====================================

UPDATE: I have found a way to extract the subtitles embedded in RM files.

1) open the file in GraphEdit or GraphStudio ;

2) connect the subtitle pin from the RealMedia Splitter to the Dump filter ;

3) "play" the graph.

P.S.: Too bad the OP doesn't give a damn about our efforts to try to help him.
(Yes, he was browsing this thread a couple of minutes ago, now=15:40 GMT).
Hopefully all this info will help other people.

Dumb filter?

Anyway:

1) find "dump.ax" and copy it to your system32 folder ;

2) register it with regsvr32.exe ;


3) copy the following files to your system32 directory:

RealMediaSplitter.ax
14_43260.dll
28_83260.dll
atrc.dll
cook.dll
ddnt3260.dll
dnet3260.dll
drv1.dll
drv2.dll
drvc.dll
pncrt.dll
raac.dll
ralf.dll
rv10.dll
rv20.dll
rv30.dll
rv40.dll
sipr.dll

4) execute the command "regsvr32 RealMediaSplittter.ax" ;

5) open your RM(VB) file in Graphedit or in Graphstudio ;

6) "erase" all the filters "after" the RealMediaSplitter ;

7) insert the dump filter and connect it to the splitter ;

8) the eighth instruction is "confidential", "classified" and "top-secret"

Hi Heggunte,

I get the dump filter from http://www.apecity.com/tivo/dump.zip
And then i get the realmedia splitter from http://www.free-codecs.com/download/realmedia_splitter.htm
Is the above the right files to use?

>2) connect the subtitle pin from the RealMedia Splitter to the Dump filter ;
I notice this step were mentioned before but in your latest 8 steps this is not there, is this step neccessary?


My graph diagram looks like following till step 5

Am i on the right way?

Thanks for help.

The picture below "shows it all":

P.S.: You will have to do some edit in Notepad, Wordpad, etc.,
because the resulting file contains some "garbage" before the actual
"subtitling content".

P.P.S.: Differently from what I said some posts above, the RealMedia container does NOT support embedded subtitles. What happens is, the subtitle streams are attached after the "official" RealMedia "End-Of-File mark", and the DS filter "Real Media Splitter" was designed to detect such "attachments" as embedded subtitles...

Hmm... my graph does not have Subtitle 00 (subtitle.srt).
I guess my rmvb's subtitle is actually graphics attacted to the movie?

Anyway, thank you again Heggunte
