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!!.
Hello,
Please follow recommendations of Chapter 4 (Multi-Overlay Support) of
“i.MX_6_Series_Ubuntu_Multimedia_User's_Guide.pdf”. In particular – section 4.1
(How to Use mfw_isink).
Also, for the mfw_isink, in order to use local alpha for video playback, please
set framebuffers to 32bpp.
# echo 32 > /sys/class/graphics/fb0/bits_per_pixel
The following may be useful.

Hi Yuri,
Thanks for replay!
For the issue that "i.MX6 Warning IPU_INT_STAT_10 = 0x00080000 " , it seems without solution to fix it. But when I switch the mode to 1280x720 @60 , the issue is disappeared. May I know what is the root cause for it?
BRs,

Hi,
So, configuration of 4 streams of 1280 x 720 @ 24fps does not work,
but 4 streams of 1280 x 720 @ 60fps - works. Is it so ?
Regards,
Yuri.
Hi,
No. I mean when I switch the resolution of screen from 1920x1080M@60 to 1280x720@60 , the issue will be disappeared.
