MKVToolNix v24.0.0 released - Page 17

I said 'packet' and not 'packets' on purpose. For FLAC one packet is typically a lot longer than 9ms -- roughly 96ms for a typical 44.100 Hz two channel file.

Ive recently been encoding some home movies and just finally got round to muxing them using 4.2, i noticed that as soon as i click the folder with the video files in, the OS (win7) will read the whole file MKV in and the ram will fill up completely to its max (4GB), after about 30-60seconds it will return to normal, if there are more MKV files it will do the same. During this time its impossible to move/copy/delete the file as windows has a lock on it.

The reason for the hang (i believe) is that its trying to extract the thumbnails and failing, i thought the reason could be the header compression option, however if i remux the file using 4.0 or 4.1.1 using default options then the files work perfectly.

Im using the latest haali splitter (with thumbnail extraction off) and ffdshow-tryouts, but i thought win7 had its own filters so that shouldnt matter anyway? Apologies if this is something screwy on my system and not a MKVtoolnix bug.

Sounds like header removal, yes.

toytown · 13th August 2010, 13:33

Sorry i meant that i originally muxed the files with 4.2 using default options, so header removal would be turned on. These files lock up explorer for some time.

If i take the 4.2 muxed file drop it into 4.1.1 or 4.0 and just click mux, this file will be ok, thumbnails are generated and everything is good. As i understand this file still contains header removal as im just using defaults.

If i take a good file and drop it into 4.2 and just click mux, i get the problems again.

I believe header removal has been in since v4.00 so if this is the case then it must be something else?

Mosu · 13th August 2010, 13:40

4.2.0 added header removal for h264 tracks by default. 4.1.0 added header removal for various audio and video formats.

toytown · 13th August 2010, 13:57

It's a bug in the DivX thumbnailer creator thats installed with the DivX codecs. I checked through the registry to see what ShellEx were being used for MKV files in explorer and found it, i uninstalled the DivX package and the problem is gone, of course i dont get thumbnails but i wasnt bothered about them either.

Im sorry to have wasted your time

Hi Mosu,

Can you pls check your rakefiles, configure and options? I have noticed that even if I disable precompiled headers,

Code:

./src/common/common_pch.h.gch

is generated all the same, and the compilation breaks immediately there (because the file is included twice).

There is a problem with ./configure, but that's not the only thing, precompiled headers are still active even if I edit config.h to remove the line

Code:

#define USE_PRECOMPILED_HEADERS 1

Thanks a lot for your help.

You're right: --disable-precompiled-headers was not doing what it was supposed to do. Bug in my configure script; fixed in Git. So please 'git pull', run './autogen.sh' followed by './configure --disable-precompiled-headers'. Afterwards you should also 'rake clean' and 'rm -rf rake.d/dependency.d'. Afterwards rake should not build common_pch.h.gch anymore.

config.h does not control the build process, only the compilation. 'build-config' controls the build process.

It works now, I was able to build 'No Talking'. Happy again.

Thx a lot for your work, mkvmerge is a great tool

I can confirm this behavior. Any file with H.264 header compression causes the DivX Explorer filter to crash Explorer on my system as soon as the file is selected. Remuxing with 4.1.1 fixed the issue.

Ritsuka · 15th August 2010, 08:09

Is there any real gain in header compression (by real meaning at least 1% of the size of an original file).
Because it seems to be a quite useless and problematic thing.

happ · 15th August 2010, 08:28

Files (x264 video, AC3 or DTS audio) muxed with 4.2.0 cause WD Live TV to stuck. Restarting system (cut of and on power circuit) and remuxing with an earlier version of mkvtoolnix fixed the issue. I can confirm Explorer crash caused with DivX explorer filter, too.

Almost none, it's a matter of few kBs for GBs large files.

Yes it is. That's why many and more and more people don't understand why it's enabled by default.
There are actually more cons than pros for this useless and annoying feature.

Why is the Playstation 3 on that list if it does not even support Matroska to begin with? If some streaming softwares can't handle it, they should be listed.

Mosu · 15th August 2010, 17:50

Because someone mentioned it to me, and I have no clue about what the PS3 supports in the first place

sneaker_ger · 15th August 2010, 18:11

I also tried MPC from 2006: no problems with H.264+AC3. I think that you probably mixed it up with the "default values" issue.

/edit: newer mplayer versions also seem to work for me (at least the builds from here)

jasonwc · 17th August 2010, 05:33

eac3to 3.2.3 has been updated to support demuxing MKVs with header compression enabled.

Unfortunately, I don't think we'll see a fix for the DivX explorer integration dll.

dejong12 · 17th August 2010, 14:52

If I try to append subs, mkvmerge crashes with error 3. What's the problem?

Mosu · 17th August 2010, 14:54

Details, please.
