playback green screen

Asked by claudio

excuseme for bad english.
The problem is a green screen showed when playing video. Still image are OK. I have verified that same problem there is with VLC, but if i set his video output options (of VLC) not to default is OK.
What can i do with openshot? i don't see a setup for output video configuration, such as hardware acceleration disable or other (how vlc can do).
Thank you

You don't have with this version an Hardware acceleration. This feature will come with the 2.0.0.

I am not sure to understand when you said what I can do with Openshot. OS is a video editor and I think that a look at our online documentation will be useful for understand what and how work OS. http://www.openshotusers.com/help/1.3/it
If you are not italian, you should find the manual in your locae easily : http://www.openshotusers.com/

Another thing is to try this FAQ : https://answers.launchpad.net/openshot/+faq/983
Like this you'll be aware if you could play this file with Openshot vias MLT. Perhaps a conversion will be useful with some tools like EnKodeur-Mixeur, Vidrop, ............ Not sure if your type of file will be played by another Linux Video Editor.
 Thanks.

Ah our answers have been crossed. :-(

 Initially, it was for this link to explain you in videos what is Openshot : http://www.openshot.org/screenshots/

That's really strange that none players, video frameworks and video editor can 't play your file, even it is AVC1format with H264 and AAC.

Do you have the goods libraries for that ?

Try this FAQ : https://answers.launchpad.net/openshot/+faq/1040

I suspect that you don't have the possibility to play/work with propriataries codecs (videos like x264 and audios like aac and mp3).
What do you in the Preferences second tabs ? You should see x264, libmp3lame, aac, 3gp,.....
Use USC and type Gstreamer, you should have bad, ugly, multiverse.............. Try Totem, he should tell you if he can't play this file and offer you download the good codec(s).

sorry for crossed message.
you say:
"That's really strange that none players, video frameworks and video editor can 't play your file, even it is AVC1format with H264 and AAC."
excuseme, bu i think is not tru..
-totem work fine
-VLC work fine, but in vlc is necessary set video option like this http://zolli.altervista.org/tmp/3.png or default but whith no acceleration
-kdenlive work fine, but is necessary set video option like this: http://zolli.altervista.org/tmp/4.png (work also X11 )

i have installed UBUNTU 13.04 64 bit from 24h, no manual setting on library or other.
I think this problem is not only mine, but there are few users that report it.
I think in most case users with this problem are switched to other editor.
i am determinated to resolve because i think that openshot is a good basic editor. I think Cinelerra is best one, but it came with a orrible interface.
sorry
thanks anyway
