Sometimes I got the following error message when starting a gstreamer pipeline with mfw_v4lsrc,
or during the running of the gstreamer pipeline ( mfw_v4lsrc->mfw_vpuencoder->h264pay->udpsink)
ERROR: v4l2 capture: mxc_v4l_dqueue() interrupt received
mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_5 = 0x00100000
mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_10 = 0x01000000
mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_10 = 0x02000000
mxc_ipu mxc_ipu: handler already installed on irq 451
mxc_ipu mxc_ipu: DC irq 451 in use
What's the exact meaning of these error message?
Does it matter?
Or can I just ignore them?
