Tool/software:
Hello Team,
We are using monochrome sensor which is giving Y10 data. We have successfully set media-ctl command to set pipeline topology for Y10 data.
Using below gst-pipeline we are trying to capture video data using format= GRAY16_LE but, we are getting failed.
Pipeline log:

- Here, we want to convert monochrome data in to JPEG using JPEG hardware encoder which is not possible directly as jpeg encoder is only supporting NV12 format as input. So we need to convert this Y10 data to NV12 using "videoconvert" plugin which accept the data in "GRAY16_LE" format and provide NV12 output.
But as per above output we are not able to get data when use format as GRAY16_LE. If we use RGGB10 format as below command then we are able to get 10 bit image data but here "videoconvert" plugin will not accept the bayer data.
Working pipeline:
gst-launch-1.0 -v v4l2src device=/dev/video-rpi-cam0 ! video/x-bayer, width=1920, height=1200, framerate=120/1, format=rggb10 ! fakesink
Please let us know why above pipeline is not working.
Note: We don't want to process data from the ISP to reduce image output latency.
