Hi there,

 

I have tested the the pipeline for cropping and rotation of imxvideoconvert_ipu on kernel 4.1.15 imx6qsabresd board. I got some issues that would like to confirm as below:

1. Max size supported for rotation is only 1024X1024.

Can anybody confirm me whether my understand is correct?

 

2. There is a problem when I try to cropping the data got from imxv4l2src. Below is my pipeline:

a) gst-launch-1.0 -v imxv4l2src device=/dev/video1 ! video/x-raw, format=I420,width=1920, height=1080, framerate=30/1 ! imxvideoconvert_ipu ! video/x-raw, width=1024, height=768 ! vpuenc_h264  gop-size=30 bitrate=2048 ! h264parse ! rtph264pay name=pay0 pt=96 timestamp-offset=0 ! udpsink host=192.168.0.100 port=1234 &

Please see my attached file for clearing about the issue with the image from client side.

 

If I try the same pipeline but change from imxv4l2src to videotestsrc, the displayed image from client side is very smooth and beautiful.

b) gst-launch-1.0 -v videotestsrc ! video/x-raw, format=I420,width=1920, height=1080, framerate=30/1 ! imxvideoconvert_ipu ! video/x-raw, width=1024, height=768 ! vpuenc_h264  gop-size=30 bitrate=2048 ! h264parse ! rtph264pay name=pay0 pt=96 timestamp-offset=0 ! udpsink host=192.168.0.100 port=1234 &

 

Please share me any hint where the issue comes from case a)

I would like to thank a lot for any support on this issue.
