Noisy green lateral band when using imxipuvideotransform

Hello,

 

I'm using gstreamer-imx on my IMX6Q based board running Debian with the following command line:

 

gst-launch-1.0 -v filesrc location=pansy-1280x720-565.rgb blocksize=1843200 ! videoparse width=1280 height=720 framerate=5/1 format=29 ! decodebin ! imagefreeze ! imxipuvideotransform ! video/x-raw,format=I420 ! imxvpuenc_mpeg4 ! queue ! rtpmp4vpay ! udpsink host=192.168.32.42 port=5000

 

The command takes a static RGB565 image, then calls the imxipuvideotransform plugin and sends the result to my host PC over the network where I use the command below to see the image:

 

gst-launch-1.0 udpsrc port=5000 caps = "application/x-rtp, media=(string)video,clock-rate=(int)90000, encoding-name=(string)MP4V-ES, profile-level-id=(string)4,config=(string)000001b004000001b59113000001000000012000c888800cd28045a14103, payload=(int)96,ssrc=(uint)3938653480, timestamp-offset=(uint)2667048504, seqnum-offset=(uint)31662" ! rtpmp4vdepay ! avdec_mpeg4 ! autovideosink sync=false

 

Everything works well but a noisy green lateral band on the host PC output window! However, if I use the same command as above on my IMX6Q board but replacing the plugin imxipuvideotransform with the standard videoconvert then the band disappears and the output is perfect.

 

Any advice in order to fix this issue?

 

Thanks in advance,

 

Rodolfo
