Repair *.MKV

Hi, All
Can anyone recommend me a tool for repairing or disassembling damaged mkv containers?
I'm tried vdubmod, mkvtool, avimux, but with some mkv files, this tools can't help me at all.

Seems some of damaged MKV's can't be repaired with existing tools, it's a another bad side of this video container.

?

if something is broken, its broken and sometimes that means broken beyond repair. tell your local mechanic hes doing a poor job if he says he cant fix your car after you drove it off a 50 story building.

get a grip.

if you actually told us what your problem was, someone might be able to help you.

Cars and videos... well... sorry for bad english:
I have a video into mkv container with 2 audio tracks & 3 subtitles (ass,txt,vobsub) total length 24 min, at 13:xx min mkv was damaged. BSPlayer/WMP plays ALL 24min without damaged ~10sec. I'm tried cut off the bad part in vdubmod... but vdubmod can't open mkv with vobsub subtitles... too bad... I'm used hiew and replace S_VOBSUB with S_TEXT/... vdubmod can open this "patched" mkv... but, only first 13:xx minutes available. I'm try mkvtoolnix to create mkv without "not needed" (maybe damaged) tracks, but this tool display ~500 errors and stops without any result. AviMux don't says anything and create a video 13:xx length... I'm think if SOMETHING played almost properly => it can be repaired... If I only can extract subtitles it will be good enough... but extract operations is possible for first 13:xx min only... This is not my first bad mkv, I see too many of damaged mkv-s and repaired/disassembled them without any big problems. Vdubmod helps me a lot (And only vdubmod!, MKVExtract (1.5.x-1.6.0) from MKVToolNix have many bugs and not good with some mkv-s).

If there is enough demand for an mkv repair tool, I may write something that extracts usable parts from a damaged file.

After I ran mkvverify, I got this problem with EBML-ID!!

In error.txt :

(mkv parser) file is b0rked:
pos. 1: 1st byte of EBML-ID indicates size larger than 4

(mkv parser) warning:
pos. 16: element size of 0 encountered


I think the mkv file is only damaged in EMBL header, so I don't think it's hard to fix??

Any idea, thanks

DivX Inc also plans some very interesting stuff in those terms with Divx 7 Plus HD and MKV they seem to even optimize their parser to read any broken stream.
So you wouldn't need to repair it @ all anymore

Well... will be good if it will supports everything that haali's splitter supports now + this optimizing. Then we don't need repair.

By the way, does someone tested Meteorite? It seems I don't have any broken mkv's so it will be good to hear if it actually works

I don't have broken MKVs at hand either. But meteorite is at least usable in Linux, so this is a clear plus. ;-)

I can say that, It best at its class, because of there is no competitor
And It's a bad way to test the program.

For a stress test the program you needed try to fix partially downloaded MKV's from P2P clients like emule/Torrents, like some movie trailers or game preview videos (like starcraft 2 or diablo 3's cinematics). There is a few trailers available recently but now nearly %80 of HD things in MKV format. So future is brilliant for such an application.

So those files has lots of broken / partial sections. Which stress the program.

Program has full of bugs also, thats why Beta. And some times it freezes on some files. But there is a tool at least for repair than preview MKV files.

It's not developed for long time. But I scheduled to resume development @Jun-July 2010 which will fix some x64 bit Vusta/7 bugs and make some core adjustments.
Thanks
