Hi all,
I have a gstreamer pipeline working on i.mx51/Linux-2.6.31:
mfw_v4lsrc sensor-width=720 sensor-height=288 capture-width=640 capture-height=480 preview=true preview-width=640 preview-height=480 ! 'video/x-raw-yuv, format=(fourcc)NV12, width=640, height=480, framerate=25/1' ! clockoverlay ! mfw_vpuencoder codec-type=std_avc width=640 height=480 ! filesink location=video.264
However, after some time ( e.g, several hours), the pipeline terminates with one of the following three kinds of message:
1.
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: IPU Error - IPU_INT_STAT_5 = 0x00100000
mxc_ipu mxc_ipu: handler already installed on irq 451
mxc_ipu mxc_ipu: DC irq 451 in use
mxc_v4l_close: release resource
ERROR: v4l2 capture: camera_callback: working queue empty
OR
2.
ERROR: v4l2 capture: mxc_v4l_dqueue() interrupt received
mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_10 = 0x02000000
mxc_v4l_close: release resource
OR
3.
ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0
mxc_v4l_close: release resource
By the way, the video source is from a tvin chip ( TVP 5150).
And the VPU firmware is 15.3.10, libvpu version is 5.0.).
What's the meaning of these error messages?
Is there anything wrong with my tvin driver?
Or should I upgrade the vpu firmware and libvpu?
Cheers,
Robbie
