Video Preview keeps going even after clicking Pause

Exactly the same problem but not with some MTS files but with pictures, titles, pictures, files 3gp done with smartphones and a track audio in mp3. For me the audio is really choppy and sometimes the video.
I try http://www.youtube.com/watch?v=AO-qca9ddqg without success.

Hi, do the files play/stop correctly if you follow the instructions at the link below?

I didn't see any instructions at the link below, it just asks some questions.
 One question it asked was "does the video play correctly if you convert to a
different format".  Yes, if I convert all of my videos to AVI, the software
works fine.

These were the instructions referred to, using ffplay & melt to play the files:

1) Does the video play and seek correctly with "ffplay"?

   Instructions: Play the video using the "ffplay" command. Use the left and right arrow
   keys to seek forward and backward (10 second increments).
       $ ffplay 'MyVideo.mp4'

2) Does the video play and seek correctly with "melt"?

   Instructions: Play the video using the "melt" command. Use the "h" and "l" keys to
   seek forward and backward (1 frame increments).
       $ melt 'MyVideo.mp4'

I'm sorry to be a noob, but are those Terminal commands?  Also, I can't keep
Openshot open now.  I have two projects, and I can open them (although the
screen dims for a moment upon opening) and when I make any changes or start any
movies, Openshot closes down.

Yes, they are terminal commands. Make sure the file names are typed in the correct case, without the single quotes shown in the instructions, i.e.:

melt MyVideo.mp4

melt command works fine, ffplay does not work (screen started out green then
faded into video.  Right and Left arrow keys had no effect on playback).

There's obviously a file compatability problem if ffplay can't play the file properly. You could try converting the files to a different format, which should sort the problem out.

Yes, converting to AVI solves the problem, it just takes a long time to
convert. Hopefully a future version of OpenShot will be able to handle
MTS files.

If your rush come from a camcorder JVC or another mark that I have forgottent the name currently :-( , there is nothing on Linux which can work natively with. it is the fault to a micro-code propriatairy. You should pass by a conversion either in command line either by a tool like EnKodeur-Mixeur. This feature is in the development version only but the future 3.0.0 stable is for soon.

Thanks for reporting this bug, but it seems that the problem is caused by MLT or libavformat (used by MLT). I don't see any way for us to modify OpenShot to fix this problem. So, I'm going to mark this "won't fix", since there is nothing we can do in our source code to fix it. If you can reproduce the problem consistently, you might consider reporting this bug to the MLT project. Thanks!

I just helped a guy on the mlt online support forum who supplied a sample file and referenced this bug report. Here is what I had to say.

"melt 00332.avi -consumer xml" displays some info about this file including:
<property name="seekable">0</property>

That means seeking is not supported on it within MLT (but it plays fine sequentially). Unlike most video players, MLT supports frame-accurate seeking, and this file fails the test. OpenShot should probably not let you try to edit this file (by checking this property).

Thanks for the info, Dan.

I understand that this is not an Openshot fault, but it would be fine, if Openshot detected that this file is not seekable and displayed some information message that he can't work with this file and it need to be converted. Or better to try to import it to better format like Kino do it.

Need to check the 'seekable' property when importing a file.

Added a check on the seekable property when importing files. A warning is presented to the user if the file is not seekable.

Same problem here as described by the starter, but with AVI files too.

Have you try the comment #2 (https://bugs.launchpad.net/openshot/+bug/876712/comments/2) ?
If yes, could you try the latest trunk version using, for sample the Daily PPA and tell us if the warming works correctly ?
Thanks.

Do you have any comprehension as to how utterly useless the information provided regarding this fix is to someone who is not a tech genius? What is it with Linux users that you all are so rude as too assume we can read your minds, and insert all of the information we need to insert that you don't provide?

I type in to, i guess, the terminal, exactly what you say, and guess what? NOTHING HAPPENS.

I've been using open shot for over a year, not too many problems, and now, for unknown reasons, it won't deal with AVI files. It just keeps on playing the file, won't stop, won't let me edit it.

Consider that the people who use this software are sometimes pretty clueless and new as to how to use Linux. So your advice, to someone who's new, is, frankly, frustrating crap.

For example, WTF is the latest Trunk version? WTF is a trunk version? Is this something to do with elephants? Maybe I need to look in the trunk of my car, perhaps, for the solution?

I need to check the 'seekable function.' WTF is the seekable function? How am I supposed to understand what this is? Maybe I should ask the elephant to see if the answer has been shoved up his trunk?

when i type in $ ffplay 'MyVideo.mp4', is that all I should type in ? Nothing happens. Should I type in 'MyVideo.mp4 instead of the actual file I want to use? I don't know. What is supposed to happen when I type this in? You don't say, you just assume I can read your mind, and gleam all the information you don't provide through telepathy or something. I don't know.

This is such a common phenomenon with Linux, that users who know their stuff routinely post fix information that is arrogant, and totally useless to someone who hasn't got a phd in Linux.

Come on, have a clue.

@ Matthew Rummler Where is anyone asking you to check the seekable property? Look at comment #16.

Maybe your time would be better spent using Google to research the things you don't understand rather than lambasting those who give up their free time to work on free software.
