Do imxvideoconvert_ipu support to resize from 1920x1080 to 800x480?

Hi,

 

I use gstreamer plugins to resize the captured image from camera (full HD) to WVGA(800x480) and stream via RTP/UDP

but the image displayed in client side has a green noise at the bottom.

With the same pipeline but change to software scaling (videoscale plugin), the green noise disappeared.

This only happens with the new version 4.1.15, the older version 3.14.28 didn't meet issue.

 

As the specification it said that IPU support up to 1024x1024 output so I think the case is in supported range. The imx-tests now has a testcase for resize from HD to WVGA not from FullHD to WVGA. Can anyone confirm me whether the IPU3 work perfectly with the resize from fullHD to wvga resizing. Currently, I don't know where the problems come from (NXP plugins or the driver itself)

 

Have anybody met same issue with me or any hint or suggestion for this?

I am trying to trace the changes from 4.0.3 to 4.0.9 of nxp plugins, but it quite difficult because there are so many changes in source code.
