PNG display error

shencheng — Fri, 24 Jun 2016 03:51:50 GMT

Hi, when i try to display a png pic from internet download its fine (attached file 1.png)

but just show error

vss/mfw_gst_vss_common.c:1003 ioctl error, return -1 twice

but when i try to display my image file (attached file 2.png) it shows source fmt error repeat

i thought my the file is 8bits

i change it into 32bits(attached file 3.png) still same

then i draw a pic with 1920x1080 and 32bits (4.png) it shows

vss/mfw_gst_vss_common.c:1003 ioctl error, return -1 repeat

so whats the different of them and how can i fix it?

Best regards
