Header stripping

[NikkiSix]

Hello guys

I can only guess how many newbie questions that will end up on a forum like this.
I googled to try to resolve my problem and found a few threads on here, though I couldn't find the exact problem I have.

I've gone through 5 seasons of LOST (720p) in less than one month. Was just getting started on S06 and I don't get any audio, and not being able to fix it is quite frustrating. I put the files on a USB memory stick and put it into my Samsung Bluray/DVD-player to watch. I ran the files in the Media Info program, and the only difference between the audio from S1-5 and S6, is that in S6 it says Muxing mode : Header stripping. Doesn't say that from any files from S1-5, so maybe that's the problem. I have MKVtoolnix (MKVmerge). Can I fix it with that?

Here's from Media Info, from a file from S6. Again, here it says Muxing mode: Header stripping, which it doesn't say from previous seasons. Other than that the info is identical.

Many thx for taking the time

Remove the header stripping with mkvmergegui, first go to File->Options and select "Disable header removal compression..." and then open the mkv and make a new mkv. Remember that next time you make your own mkvs...

After enabling the Disable Header Removal Compression... setting you just exit mmg and restart it for the change to take effect.

Only took about 30 seconds/file (2.2gb each) and works like a charm.

Many many thanks

Is there any program that i can add it one folder with mkv files with "header removal compression" and remove it from ALL the mkv files there is in that folder and subfolders without writing again the mkv file simply remove that "header removal compression".

A lot of thanks.

[jagabo]

mmg is a GUI front end for the command line mkvmerge.exe. So you could write a batch file that automatically remuxes all the files in a folder using mkvmerge.exe.

[poisondeathray]

I think he wants to do it without remuxing or copying the file

mkvpropedit can do this for some parameters, but I don't think it can for header stripping

So I think the answer is NO.

[jagabo]

Since undoing the header removal will require the file grow larger (ie, it has to put the headers back in) I'm pretty sure that program won't work.

[fits79]

Yes i want without remuxing or copying the file.

A simply gui program that can remove all audio header compressation from all mkv files i have in one folder without any other change at the mkv files only the removing of audio head compressation.

A LOT OF THANKS.

And mkvtoolnix it doesn't do either of these.

I know it can remove the audio head compressation but i don't want only that.

[jagabo]

Changes that require data be inserted or removed from the body of the file cannot be made without a remux.

[fits79]

Ok then a program that can remux a lot of mkv files to the CORRECT path tothe folder i put.

Is there any that kind of program?

[poisondeathray]

Yes, like jagabo suggested above you can do that with a batch file and mkvmerge.exe

eg

[fits79]

What is that exactly?

A command line for mkvtoolnix program?
How it work?

And there isn't any gui program that it will do the job to many mkv files?

[fits79]

So there isn't any gui free program that remove the audio head compression to a multi mkv files?

If we knew of one we would have told you.

the option to turn off/on header stripping is gone. it's currently off permanently as now there is no way to turn it on.

[jagabo]

Guess I'll have to stick with 5.8.0. But I'm not sure what you mean by " it's currently off permanently". The option in the old dialog was called "Disable Header Removal Compression..." so turning it "on" disabled Header Removal Compression (it was off by default). Are you saying all files muxed with the new version use Header Removal Compression? Could you upload a small file muxed with the new version? Or just show a MediaInfo report for a file muxed with it?

[aedipuss]

header removal compression is now always removed if it was there, and can no longer be used.

[fits79]

Already know the program mkvtoolnix but IT DOESN'T REMOVE AUDIO HEAD COMPRETTION TO MULTI MKV FILES ONLY TO ONE BY ONE SO.....

I want a gui program that can remove the audio head comprettion to a LOT OF MKV FILES NOT ONLY ONE BY ONE...

[El Heggunte]

It seems you'll have to hire a programmer for that task.

He's NOT joking, despite the "smiley face". The smiley face means he is amused by your problem because you refuse to believe what you are being told.

jagabo told you this: "If we knew of one we would have told you."

Refusing to believe what you have been told is not likely to magically make a program exist that does not exist now, but you are certainly welcome to try this interesting method of new program creation.

Wow, that's a surprise.

This has been a recurring pattern of his...

Ok then is there an program that it scan a full hard disk and tell us which mkv has audio head comprettion so we remove it one by one?

[Baldrick]

Mediainfo can open folders and you can check the Muxing mode : Header stripping for each file.

You can probably write some script for the mediainfo cli also.

[fits79]

STILL YOU DON'T UNDERSTAND I DON'T WANT to must check one by one all mkv files i have to the hard disk but i want a program that search ALL THE MKV FILES at any drive and report me which of these has audio head compression so i change it one by one...

Do you know any that kind of program?

[Baldrick]

No such program. You must write a script/batch.

[fits79]

If i know create a cript/batch i would created.

But i don't want.

And i don't believe there isn't

Header compression was not used in the older versions of mkvmerge but was added a couple of years ago. It's hard to believe that the author would take it back out because he insisted that it was part of the mkv spec and refused to remove it after he started putting it in. I'm wondering if ffmpeg uses an older version because I don't have it in any of my newer mkv files or if the author did remove header compression after tons of complaints.


It's simple enough to create an ffmpeg script to remux a folder full of mkv files. You don't need to search for files with header compression, just run the bat file on the whole folder.

It only takes a couple of minutes (maybe a little more depending on the size of the folder) to do a whole folder. Just make sure you place a copy of ffmpeg.exe in the folder along with the bat file. Copy text below in notepad and save as RemuxMKV.bat

for %%a in ("*.mkv") do ffmpeg -i %%a -vcodec copy -acodec %%~na.new.mkv


Make sure there are no spaces in your filenames or the files will be ignored. Here's a VBSscript to replace spaces with dashes. Just paste into notepad and save as Replace-Spaces-With-Dashes.vbs...

dim objFileSys, file, folderName, folderObj, fileColl, objRegEx, newFile

set objFileSys = CreateObject("Scripting.FileSystemObject")
folderName = InputBox("Enter the full path where the files are located.", "Full path is required")

set folderObj = objFileSys.GetFolder(folderName)
set fileColl = folderObj.Files
set objRegEx = new RegExp

objRegEx.Pattern = " " ' the pattern is one space
objRegEx.Global = true

for each objFile in fileColl
newFile = objRegEx.Replace(objFile.Name, "-") ' each pattern gets replaced with one dash

objFileSys.MoveFile objFile, folderName & "\" & newFile
next


...or you can just use mkvmerge to manually change one file at a time if you'd like.
