MKV question


Question

I recorded a webcam capture using some software. I recorded the 2 hour long video using the MKV container with the Mp4v video codec (I think I explained that correctly). I can view the video in VLC, but I cannot seek through the 2 hour long video. I tried to extract the video using MKVExtract - When I tried this, MKVExtract could not find a video within the MKV container. At this point, I figured I would just convert the video to something usable, but even that has not worked. Any advice or suggestions?

Thanks

It was built into the webcam software.

I tried WinFF and SUPER to no avail. Unless I am not setting up the settings correctly.....

What I find interesting is that VLC will play it, but I don't have the entire functionality of a regular video (IE seeking)

Try demuxing it with mkvmerge (from here), you should be able to either extract the tracks (and add them to a new file), or just get it to re-write the file all together.

mp4v can be many things, it's just VLC generalizing..

Download mediainfo and check what the video codec really is

http://mediainfo.sourceforge.net/en

If it's an AVC file then mkvextract will have problems. It will demux but it will only be a raw .h264 file which just makes remuxing more complicated (desyncs etc). Personally I'd dump whatever webcam program you're using and encode the raw stream with MeGUI.

@kubi789

As x9248 said use Media Info to get the spec log of your video. And also dump whatever program you are using to record your video.

Post your Media Info video log spec here and we'll start from there.

Tip:

For webcam recording I suggest using WinAVI Video Capture its free. (Its under the Download section.)

If you want to convert to other format use Xvid4PSP. it easier to use than Megui.

Thanks for the help guys-

I downloaded mediainfo and here is what I got: 2n9aix4.jpg

Thanks for the program advice Blaze. My only problem is that I used Linux to capture the video via a webcam. Ever heard of a Sheevaplug? That's what I used as my Linux box. Sheevaplugs are pretty sweet - I just need to expand my knowledge of Linux, and in this case, Debian to be able to fully put the Sheevaplug to work. I am getting there. Anyway, I digress.

Just so we aren't confused now. I recorded the video via a LInux box and am now trying to edit and view via a windows machine. My Linux knowledge isn't great enough to edit a video in Linux :blush:

Have you tried Freemake Video Encoder? - www.freemake.com

At only 100kbps I do not recommend recoding it to another format, the video must already be low quality and it will just make it worse.

Prolly a dumb question, but have you tried a different player? VLC is just meh but you may be opposed to other players so I dunno :p

Also try remuxing in mkvmerge. Could be cue problems when your recording program muxed it itself.

I've never experienced ASP in a matroska container so I'm quite clueless on this. Good luck.

I will give freemake a try. Just for the hell of it.

I tried 2 different players. SPlayer and GOM Player. Neither worked. Any other media player suggestions?

MKVmerge can't load my MKV file - says "Input file does contain any tracks"

Thanks

it has been duly noted that I will never use this combination of mkv and mp4v ever again. Unfortunately Copernic the repair tool didn't work and nor did the player. I appreciate your suggestions though. Perhaps I should just use camstudio and re-record the whole thing.

Just tried it. That didn't work either. It seems that none of the converters can identify the MKV file.

Even AVIDemux won't work. I'd say I am sunk guys. I will never encode an mp4v into an MKV container again.

Does anyone at least know why this combination doesn't work?

Thanks for all the suggestions everyone.

That does sound like an odd combination, most MKV files are using the h.264 codec.

If AVS Video Converter won't work either then I would say you are truly sunk. Unless you screen grab while playing the video?

Unless the webcam software can allow you to write it as a DVD disk? Then you'd be able to convert it to MKV using that piece of software that takes DVD tracks and converts them to DVDs (sorry I can't remember the name right now :/)

Hi Mr. Spoon. Are you thinking of the program Avi2DVD? It can take MKV files and convert them to DVD format. But sadly, it wouldn't work.

Thanks BudMan. Unfortunately, Mediacoder didn't work either. It just hangs trying to read the MKV. Also, the MKV is too large to post.

No its not - its 80 some MB.. You could post that all kinds of places - don't you have a dropbox - just share it. Or megaupload, or sendit, etc. I could prob list of 100 places you could post that file so others could download it for free.

I just looked at a 230MB + capture file that a guy in denmark posted up for me to look at. Now if it was 8GB or something then yeah might have a bit of a problem.. But 80MB shoot that will download in like 30 seconds. Given it might take you a few minutes to upload, unless your on dial up or something it should only be a few minutes to post that.

There's nothing wrong with putting DivX/XviD in an MKV container (MKV is quite flexible and can hold multiple formats), the problem is that the encoding software has written out the file badly/wrongly.

I use it and never had any issues with it.
