gst pipeline conflict with ldb driver

I am using the ldb driver for my display, and want to stream my video from fb0 simultaneously over RTSP using a gst pipeline.

 

# gst-launch fbdev do-timestamp=true ! imxipuvideotransform ! video/x-raw,format=NV12 ! imxvpuenc_mpeg4 bitrate=4000 ....

When I attempt to simultaneously use a gst pipeline and the ldb driver (which uses fbdev)

...linux/drivers/video/fbdev/mxc/ldb.c

 fbdev crashes and I cannot launch my RTSP server. 

 

If I disable the ldb in device tree the RTSP server is fine. 

Is there special configurations I need to set for the ldb in order to avoid this conflict?

 

Thanks,
