I can't import .mkv files

I’m using Windows 7 and I’ve alredy intalled the “ffmpeg-win-2.2.2.exe” that should allow me to import .mkv files.

Everytime I try to do that, import stops at 1/3 and the remaining time just keeps getting bigger. Yesterday I’ve left it alone for couple of hours and it showed me 52 hours.

Can anyone help me ?

There may be a problem with that file. Does it work with other files?

I tried it with two .mkv files and one .avi file. None of them worked.
I also have one .mkv fle (it’s Deadpool 2 trailer) that can be imported but the sound is just screeching.

btw those three files that didn’t wok are full lenght movies (2 hours), is that a problem ?

The length of the file shouldn’t be a problem, but the format could be. MKV is a container format, and FFmpeg will only be able to extract the audio correctly if the codec used in the MKV (which could be almost anything) is supported by the installed version of FFmpeg.

Probably a good thing at this point is to check which version of Audacity you have, and if Audacity is installed correctly.
For the Audacity version, look in “Help menu > About Audacity”.
To Check FFmpeg, open the Audacity log. Depending on which Audacity version you have, the log will be somewhere in the Audacity Help menu.

Relaunch Audacity, then open and save the log. Attach the saved log file to your reply (see: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1)

That’s the installation file. Did you run the exe file to install it?

Check [u]Libraries[/u] to make sure it’s actually installed.

MKV is a “container” that can contain a variety of audio & video formats.

FFmpeg works with almost every audio/video format but you can check the actual format details with [u]MediaInfoOnline[/u].

I assume you can play the files? What player software are you using?

No. As far as I know the only audio or video file with a size limit is WAV (4GB).

…Some Googling found [u]MKVToolNix[/u] which includes mkvextract and it looks like that can extract the audio, but it looks like a command line tool.

Here are the screenshots



I download ffmpeg though .zip and then manually located it with tutorial.

I checked the detail of the file but I don’t know what any of it means. I added .txt file as an attachment.

Yes I can play the files, both in VLC and Windows Media Player.

I don’t know how to use command line tools, I’m studying media so I’m kinda bad with anything that look even little bit like programming.
Harry.Potter.6.a.Princ.dvojí.krve.2009.1080p.Bluray.x264.AC3.5.1.CZ.Dabing.mkv_MediaInfo.txt (3.65 KB)

That all looks OK to me and FFmpeg can normally decode AC3 audio…

Good! VLC should be able to [u]extract the audio[/u].
