Errors about IPU

Recently, I use IPU to convert color space yuv422 to yuv420.

When I run "gst-launch mfw_v4lsrc device=/dev/video0 ! mfw_v4lsink" script and then run my application, the ipu runs fine.But if I directly run my application, the IPU alert "imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_10 = 0x04000000 imx-ipuv3 imx-ipuv3.0: ERR:[0x92526400]-no:0x10 "wait_for_comp_timeout" ret:0,line:2891".

What‘s wrong？

I add some debug information in kernel files "drivers/mxc/ipu3/ipu_device.c", and blocked in "wait_event_interruptible(thread_waitq, find_task(&tsk, curr_thread_id));"

Hi liang

for simple ipu examples not using gstreamer one can look at

ipu-examples release notes - v0.1
