ipucsc crop and upscale

allanmatthew — Thu, 03 Sep 2015 22:46:11 GMT

I'd like to crop and upscale (basically zoom) a video feed coming from mfw_v4lsrc. Specifically, I'd like to crop a 640x480 video by 60 pixels on the top/bottom edges and 80 pixels on the right/left edges and then upscale that cropped video up to 1280x720. I was hoping I could do that with the pipeline:

gst-launch mfw_v4lsrc ! \

'video/x-raw-yuv, format=(fourcc)I420, width=(int)640, height=(int)480, crop-left=(int)60, crop-top=(int)60, crop-bottom=(int)60, crop-right=(int)60' ! \

mfw_ipucsc ! \

'video/x-raw-yuv, format=(fourcc)I420, width=(int)1280, height=(int)720' ! vpuenc ...

but vpuenc's source caps show an image of size 1152x592. I can make this work by forcing the capsfilter between ipucsc and vpuenc to have a width/height of 1440x848, but that seems very cludgy. Whats the right way to do this?

This is running on the 3.10.17_1.0.0ga BSP.

Hi,

the new BSP solved the issue?

I encountered the same issue, with different resolution.

a reply will be appreciated, :-)
