imxg2dvideotransform: wrong transformation with crop metadata #303

Closed angelobt closed 1 year ago

angelobt commented 2 years ago

Hi,

running this pipeline

GST_DEBUG=2 gst-launch-1.0 videotestsrc ! 'video/x-raw, width=720, height=576, framerate=25/1, format=UYVY' ! videocrop left=16 right=16 top=48 bottom=48 ! imxg2dvideotransform ! 'video/x-raw, width=688, height=480, framerate=25/1' ! imxg2dvideosink

I get this output

Please could you help me understand what I'm missing ?

I forget to say environment:

cpu: imx6Solo yocto: hardknott kernel: 5.10.35

I can reproduce this in current OE master. This only happens if videocrop is inserted. I'm looking into it. Keep in mind though that videocrop will copy pixels via the CPU. The imxg2dvideotransform element supports the GstVideoCropMeta. I currently do not know though if that meta can be inserted as an alternative to copying pixels via the videocrop element. Nevermind, this last seems to be wrong - videocrop does not copy pixels. But the alignment is still wrong.
