Hi All,

     I have created a fsl-image-gui app with qt4 which overlay widget on camera captured image renderd by gst,used tvsrc and mfw_v4lsink.

     The app runs well, but when I want to record screen with ffmpeg into xxx.avi, there's only the image-gui.I can't record creen with both gui and video.

     As I know the area above the video windows should be transparent, fb0 is qt program and fb1 is mfw_v4lsink.

      Does anyone know about this? Thanks a lot.

    

      Device : iMx6q customer board

      Display: 8bit LVDS 1024x768

      Firmware: Yocto Linux

      Kernel:  3.0.35-4.1.0+yocto

      arm-gcc: 4.6.2

      oft changes: qt-every-where-4.8.6, gst 0.10.36(with gst fsl plugin 3.0.8 installed)

      app: Qt widget with camera captured image renderd by gst, used tvsrc(v4l2 driver for ADV7180, PAL 720x576) , pipeline , mfw_v4lsink

Regards,

could you give me your test steps? let me check it and reproduce it on my board, and yocto uses gstreamer 1.0, maybe you can use it and tell me the result.
