I use the board of VAB820 based on imx6q to playback 4 path video with mfw_isink, the command as follow:

gst-launch-0.10 playbin2 uri=file:/home/linaro/MPEG4_1280x720_4Mbps_24fps_AC3_BigBuckBunny.avi  video-sink="mfw_isink disp-width=720 disp-height=480 axis-top=0 axis-left=0" &

gst-launch-0.10 playbin2 uri=file:/home/linaro/MPEG4_1280x720_4Mbps_24fps_AC3_BigBuckBunny.avi  video-sink="mfw_isink disp-width=720 disp-height=480 axis-top=0 axis-left=800" &

gst-launch-0.10 playbin2 uri=file:/home/linaro/MPEG4_1280x720_4Mbps_24fps_AC3_BigBuckBunny.avi  video-sink="mfw_isink disp-width=720 disp-height=480 axis-top=500 axis-left=0" &

gst-launch-0.10 playbin2 uri=file:/home/linaro/MPEG4_1280x720_4Mbps_24fps_AC3_BigBuckBunny.avi  video-sink="mfw_isink disp-width=720 disp-height=480 axis-top=500 axis-left=800" &

 

Sometimes it can work. But it usually appears black screen.  Get the abnormal info from dmesg as follow:

imx-ipuv3 imx-ipuv3.1: IPU Warning - IPU_INT_STAT_10 = 0x00080000

imx-ipuv3 imx-ipuv3.1: IPU Warning - IPU_INT_STAT_10 = 0x00080000

imx-ipuv3 imx-ipuv3.1: IPU Warning - IPU_INT_STAT_5 = 0x88800000

imx-ipuv3 imx-ipuv3.1: IPU Warning - IPU_INT_STAT_10 = 0x00080000

imx-ipuv3 imx-ipuv3.1: IPU Warning - IPU_INT_STAT_10 = 0x00080000

 

Sometimes it cannot work , and will product following error:

  mxc_sdc_fb mxc_sdc_fb.0: timeout when waiting for flip irq

  vss/mfw_gst_vss_common.c1003 ioctl error, return -1

 

The software environment:  Ubuntu 12.04   gst-fsl-plugin-3.0.11 

 

From the user guide (i.mx6 Series Ubuntu Multimedia User's Guide), it should  be supported.  Please give me some advice to fix it .  Thanks!!.
