Red noise in gstreamer video

Hi everyone,

I'm running kernel 3.0.35 and using GStreamer to play a video in an XWindows QT application.  The video plays correctly, but I see red dots flickering in various parts of the image.  I've tried this with mfw_v4lsink and mfw_isink, and it happens with both.

My hardware is based on an i.MX6 solo processor.

Does anyone know how to fix this problem?

Thanks

Marlon

Marlon, have you verified that you can (or cannot) play the video correctly from the command line?

example:

$ gst-launch -v playbin2 uri=file:///somevideo.mp4

Actually one more question: how do I know which bsp I'm using?  I used Yocto dora, and just modified it to use the wandboard kernel 4.1.0, but is that all there is to it?

Thanks for the response,

I'm using Yocto dora, and the kernel I'm using is wandboard 3.0.35 4.1.0 with some modifications for my hardware.  I modified fsl-image-gui to add xf86-video-fbdev, and I changed xorg.conf to use fbdev instead of vivante (vivante gives me a black screen).

The application uses Qt for XWindows, and Gstreamer mfw_v4lsink.  I call gst_x_overlay_set_window_handle to attach it to the application and play the video.
