    I recently downloaded some .mkv files for the first time and when attempting to play them in MPlayer they work fine for a while, and then in the middle of the video it disappears with no error messages. I tried playing them in VLC and at the same point in the video I get an assertion saying "invalid track index" or something like that. If I fast forward a few seconds past the point then the video continues playing normally. The problem is that these specific .mkv files have about 2-3 of these points throughout the file and its annoying!

    Is there any way using FFMPEGX to repair these files without re-encoding them?

    the tools section - video repair. try a couple and see if they work on it. most likely a poorly made avi and not likely a fix will work without redoing it over again with the source. the chance you take d/ling things.

    I know you can repair AVI files, I was wondering if there was a way to do something similar with MKV files. It doesn't really matter, I'll just convert them to m4v or avi.

    Thanks!

    have you put any consideration towards the fact that your computer just doesn't have the processing power to handle the streams within the mkv container? if your computer detail info is current, you appear to have a G4 533 mhz processor, maybe dual pro digital audio version? if the video stream within the mkv is AVC/h264, that will most definitely be too much for your processor to handle without stuttering. check the streams under VLC (window>info) to see if it is AVC. if so, use an application like MKVToolnix to separate the streams and run the video through ffmpegx using one of the xvid/divx settings. of course i may be barking up the wrong tree, who knows...

  5. I am thinking of make such a program that fix half downloaded MKV files like DivFix++
    One day, I give up thinking and started to make one.

    Awesome! Well done.
    Can you elaborate on the kinds of issues it can and can't fix? Is it 'only' about partial files?

    Well done indeed!
    I personally don't have a need for an MKV fix tool at the moment, but I could see many people would find it useful.

    And Happy Birthday for yesterday

    Program tries to remove empty sections and try to rebuild whole index. So works on every type of files, If it's partially downloaded file or not.. You might have "non seeakable" MKV movie but it's not broken. Tool could place index to that MKV and your file is seek-able now.

    It theoretically could fix every MKV file on the wild, but there is some bugs at in practice. Those will fade out with time and coding

    I've tried meteorite with some small mkv samples I have and it works just fine.

    But, recently I've come across 2 mkv files with 7 Gb each.
    Both reporting EBML errors and playing time less than the real total length.

    I've tried to use meteorite with them, but there is no output after an entire night processing (just the CPU at 50% occupancy).

    Perfectly normal. Because my program is not complete. I just open source code at my birthday for give a birthday gift to humanity and compile for 3 major distributions, thats all. But it currently could fix >%90 of mkv files which is good thing. At least, you have a tool that could recover some of your mkv files since there is no other software could help you.
    I paused development for a while because of my ther projects like SamyGO and wxHexEditor. At Jun~Jul 2010 I am planning start development again and wish to fix some bugs like x64 bit problem on Vista/7 OSes.

    If you like my tools, please support it via feedbacks, donations(I really like this choice more than others ) and sharing at your profile like facebook and/or other web pages
    Thank you for using.
    Erdem.

    I download this file but Kaspersky won't let me run it. It's sending me a message that there is a hoax.win32.agent.wc - Is this true? If not then how can I use this sw? Thanks

    It's false positive. Ignore that warning or recompile it from sources. source code is open.

  16. Do you sure if your file has the remaining part?
    Sorry but no one could fix your file if it doesn't have the data after that point...
    If you don't believe, open it with an hex editor like http://wxhexeditor.sf.net and see it by your own eyes. It's empty!

    I belive that there are something in this file, but where is the data has gone, I do not know, because i make the files myself and watch before. could be something wrong,

    One thing else, why windows 7 explorer hang when reach some NKV files (Not all mkv files)
    and, what is the best free or paid program to use for joining and splitting MKV file..

  19. @rzainaddin if you could put the file online than I can analyze it. But I believe it doesn't have any data after that location. Sometimes HDD crops the file. There is nothing to do... Win7 hangs due that corrupted files. And I don't know which one are best or not but you can try AviDemux for the job...

    @cH40z-Lord I don't know what is your problem. If you can upload those files to internet, than I can download them, inspect them and fix the Meteorite. Also you can detect and fix the issue and send me patch for merging, since my tools is opensourced

    Thanks

    My Dear Death_Knight

    From this file, I made already a DVD, and still I have this DVD and I watch it some time (Complete movie), and again, I edited this movie and add subtitle and chapter, (this file was MP4 and convert to MKV with MKVmerge), It mean, this file was perfect before it damage, But I believe that when I had a problem with my HDD, then I had to recover it. It seem full size had been recover, 2.6 Gb, but not full data. I found same problem with MP4 file.

    Thank you for your comment and wish you all the best in your project....

  21. Understand the situation.
    All I wanted to say that, Meteorite (generally) recovers parts after corrupted region.
    I can watch half videos over emule and torrent streams which has thousands corrupted emptry regions in it...

    I think you can use tool "CDCheck" for re-recover your file from DVD. It will try to recover each sector from DVD. Also trying to do on different DVD readers might lead recover more data. Than re-try to fix those files. That is least thing that you can try...
    Best Regards,
    Erdem

    Had a HDTV.MKV that stops after a couple minutes playback. MkvToolnix remux reports an error in the AC3 and does not complete. Tsmuxer won't take it at all.

    Tried the latest version of Meteorite and it does the same as this gent reported;

  23. It's just a bug.
    Can't find time to fix bugs this months, but I am planning to remove those bugs before die.

    Meteorite works well. But, the developer has shelved it for obvious reasons (lack of support).

    Is there a substitute?

    Thanks

    Hello there,

    just found Meteorite for an unseekable mkv. It played fine on the computer, but the BluRay-Player didn't seek through it, just froze... I dropped it in Meteorite and - lo and behold, after less than 2 minutes (comparatively small file, external USB-drive) it is seekable now and plays just fine!

    Thanks so much for all the effort!
