...is not a valid video, audio, or image file.

I've got the same error on Manjaro (an arch derivated) and on Linux Mint.

I've identified and informed Jonathan since the beginning of November about this bug in Libopenshot. And with any kind of files (audio, images, videos) and even a file created with the animated 3d title.....................

At first look, the bug with swig seems to came back and despide several update of Libopenshot he is still present.

Now we must be patient and wait the good update.......

Thanks a lot to help us to improve Openshot especially this version.

Same thing with the last update

The problem come from local settings:
My local is french, in french we use "," for "." on float number.
JSON generated from importing a file is corrumpted exemple:
The field with french local is:
    "duration" : 113,1296844482422,

     !!!! Duration = 113 next field is 1296844482422 without value !!!!

With english local:
    "duration" : 113.1296844482422,

# {
        # "acodec" : "",
        # "audio_bit_rate" : 0,
        # "audio_stream_index" : -1,

Solution :

You need to force local here : openshot-qt/src/windows/views/files_listview.py

Insert this at line 41:

  import locale
  locale.setlocale(locale.LC_ALL, 'en_GB.utf8')

Hi Yohan,

Thanks for the trick. Hovewer, it doesn't work for me. Same result with the last update of LInux mint and Manjaro.

Okay i know why it's not working you don't have locale en_GB.utf8 generated on your linux.
You can generate : https://wiki.archlinux.org/index.php/Locale

You can choose an other locale i.e en_US.utf8.

Do this command to show your current generated local :
   $ locale -a
C
C.UTF-8
           en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
          en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
fr_BE.utf8
fr_CA.utf8
fr_CH.utf8
fr_FR.utf8
fr_LU.utf8

Generating locales

Before a locale can be enabled on the system, it has to be generated. The current generated/available locales can be viewed with:

$ locale -a

I added to openshot-qt/src/windows/views/files_listview.py appropriate (given lines) with the appropriate indication .utf8.
Not worked.

I decided to use another solution.
Instead, for example: en_GB.utf8 - I put between brackets C:

import locale
locale.setlocale(locale.LC_ALL, 'C')

I made the command:
sudo python setup.py install

I run the OpenShot-qt.
The result: the program has opened my .flv file without a problem, .mkv, .mov and .mp4
:)

Thanks a lot Yohann and my.swiat.

A quick test on Linux mint 17.2 using the both methods and that works with the last update of this year of LibOpenshot and the rev.

ON LMInt my locale are :
 olivier@siriel ~ $ locale -a
C
C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
                    en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
                  en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
fr_BE.utf8
fr_CA.utf8
fr_CH.utf8
                fr_FR.utf8
fr_LU.utf8
POSIX

I have not run the setup but just like usual the following command in the src folder after updating the branch.
python3 launch.py

I have been able to run a 4K film and another one in the same time.
Great

Rev 849.
Hovewer, the player run slowly with a 4K.

Soon, I'll test on Manjaro.
