Hello! I installed cheese, and I am getting the error I posted. I use Linux Mint 18.1 Cinnamon, and works well. I have uninstalled and re-installed, and don't understand why the error. Ideas??

Thank you!

Dave

what is the error get me while i am hot??

what media player are you trying to playback webcam video on?

show the fullname of file too?

maybe your video player can't handle that format, or needs a codec before it can?

smiles keep it simple. need for you to open a terminal and type cheese or what ever program and watch the output ok. push enter
make sure we have everyting installed for v4linux. or what ever the devs are pushing

I typed in cheese and got 6 different messages abour "failing".dave@dave-Inspiron-5537 ~ $ cheese

So that is what I had. I installed cheese from the repository.
When I click on cheese in the menu, and all it did was flash a picture me and go to a blank screen.

Thank you all for your help!
