Avidemux problem

[RollForever]

Every time I try to put a video (Mp4) into my Avidemux editor, it says that it cannot find a demuxer and that it can't open the file. It works in my VLC and other media players, just not in the editor. Again, it's an Mp4 file. Somebody please help me.

Post the details from the mp4, use mediainfo, view->text. Avidemux might just not support the video or audio codec in that mp4.


And are you using latest avidemux 2.6.4? Or maybe try an older version.

I looked at your profile and you're running linux mint. Avidemux 2.6 isn't in the ubuntu repos, and most mint is ubuntu or debian based, so it probably isn't in the mint ones either. I use ubuntu (though I've had mint installed before) and I'm pretty conservative about software sources so I use 2.5.whatever.

You could install 2.6 in mint but you'd have to add their ppa and build it. I haven't done this myself. I'd rather wait until it's in the repos and there are other good linux editors/converters like kdenlive, openshot, and pitivi for a start. Actually I think the selection is better in linux. In fact I've used openshot to convert files everything else choked on.

As mentioned, you need to know what codec you're talking about. Is it just one file? Mp4 isn't a codec, it's a wrapper. It can contain a number of codecs. If it's mpeg4 visual or something like that it's easier to find software to edit. H.264 is harder.

Yes, all the files are mpeg4.

Yes, all the files are mpeg4.

There is more than one type of mpeg4 video. That didn't help, I'm afraid.

But it's a number of files? I've used avidemux often in ubuntu. it rarely chokes on any mpeg-4 type, just examples made with flaky codec versions.

You need to do as baldrick suggests and post mediainfo text output. If you don't have it get it. It's in the ubuntu repos and therefore also for mint.
