Someone can help ?

I am trying to simulate capturing from video file.

When I am playing the video using Qplayer (From Qt library)

Main screen images (in background) disappeared.

    Solved!

    I notice that when using the viewPort method it's the only reason from that problem.

    I tried to use the examples of the QMedia player from Qt documents with no success

    (I couldn't set the player into my GUI)

    I used the OpenCV project in order to create my capture player using Stephen Nneji code

    from the link: http://codingexodus.blogspot.co.il/2012/12/working-with-video-using...

    Hope I could help for some last souls :)

    might be one of the many things that APM Planner 2 hasn't finished.

    Does it work on Mission Planner?

    Also the video you attached needs to be renamed after download with the .mp4 extension. Nix may be ok without having file extensions, but windows needs them

      I didn't try, I am developing only on APMPlanner 2 open source version

      Linux Ubuntu 14.04 TLS

      With Qt 5.5

        Mission Planner is also open source and I am pretty sure can be made to work fine using Mono and have also heard it works ok with Wine. It is much more feature complete. Doesn't lag behind updates to ArduPilot and seems to be far more stable [at least under Windows]

        Just saying it may be an alternative.
