Minor point, I would recommend creating a build subid, cc into it and 
the "cmake path-to-source-dir".  I think most KDE stuff doesn't like 
building in-tree.  Equery doesn't identify any package for qt5_wrap_ui.  
If it's part of the source, then you might need some parameter for 
cmake, or else there's another dependency not packaged in Gentoo.

So the method does exist.  ROFL  I wasn't worried about converting it at
first but since doing so might fix it, I gave it a shot. 

Thanks.

Yea, that's abit overwhelming.  Usually it's easier to google ffmeg
and the task you want to do (e.g. google "ffmpeg remux avi to
mp4"). The first hit explains it nicely:

https://ottverse.com/ffmpeg-convert-avi-to-mp4-lossless/

FWIW, the command is

  ffmpeg -i input.avi -c:v copy -c:a copy output.mp4

I looked at the man page.  I felt like I was trying to become a brain
surgeon.  Then I had a thought that this suggestion made me think of. 
I'd prefer a .mp4 file anyway so I used the video download helper tool
in Firefox to convert the video from .avi to .mp4.  When it was
completed, the video shows the right play time and it works as it
should, plus I have my preferred .mp4 file. 

While it may be a odd workaround, it did work.  I wouldn't have thought
about that if it wasn't suggested to re-encode the file. 

Thanks to all.  Took a strange path but got what I wanted.  ;-)

That's what I'd do. Try remuxing first (it can be done losslessly).
To remux losslessly, use the "copy" codecs for both audio and video.

It started with .rar files.  See reply to other Andrew.  ;-)  I figured
out, with googles help, how to unpack them and got a nice .avi file.  It
just gets weird at the end.

It started out with a bunch of .rar files.  I've never ran into those
before.  Anyway, figured out how to deal with it and got the video but
there was a error about "unexpected end of data" in the last .rar file. 
The others were fine.  I suspect that is what lead to the video playing
longer than it shows.  The end result was a .avi file.  It plays fine
until the last bit, where it goes past the expected end. 

I've never dealt with this before so it could be a one time thing or it
could be expected behaviour that needs fixing.  Just in case, I'd like
to know how to fix it for this one and any others I run into. 

Thanks.

	Seen the same sort of behaviour in vid's "liberated" from youtube using 
youtube-dl. I can't remember if I found the problem. What format are you 
using? For example mkv has mkvalidator which will check the integrity 
and I thing mkvclean to fix errors etc.

More than likely the metadata in the file is off.

This playback issue can happen with VBR MP3s and also Oggs as the length of
the file can be spoofed in the header.

Hi,

I have a video that does something weird.  The video plays about 6
minutes or so past the length it should.  During that extended time, you
can't fast forward, pause or anything either.  I've ran into this a
couple times with my deer camera and thought it odd but didn't worry
about it.  My question is, can this be fixed somehow?  Can I get mplayer
or something to process the file and adjust the time it thinks the video
is to what it actually is? 

Bonus, how in the world did it get that way? 

Thanks.
