GStreamer MIPI-CSI 10bit raw format

#1

Hi, I’m trying to run GStreamer pipeline with monochrome 10-bit CMOS. The V4L2 interface works fine, I’m able to stream all frames using v4l2-ctl using formats Y10 and BG10. (I tried with MEDIA_BUS_FMT_SBGGR10_1X10 and MEDIA_BUS_FMT_Y10_1X10 on the CMOS driver). But GStreamer does not work with Y10 or BG10 format, and there is no way to stream data using GStreamer v4l2src and keeping a 10-bit raw video stream.

The ISP21 capture driver doesn’t provide Y10 or BGGR10 as output format, if I run v4l2-ctl --list-formats I have only the following options:

# v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
	Type: Video Capture Multiplanar

	[0]: 'UYVY' (UYVY 4:2:2)
	[1]: '422P' (Planar YUV 4:2:2)
	[2]: 'NV16' (Y/CbCr 4:2:2)
	[3]: 'NV61' (Y/CrCb 4:2:2)
	[4]: 'YM16' (Planar YUV 4:2:2 (N-C))
	[5]: 'NV21' (Y/CrCb 4:2:0)
 	[6]: 'NV12' (Y/CbCr 4:2:0)
	[7]: 'NM21' (Y/CrCb 4:2:0 (N-C))
	[8]: 'NM12' (Y/CbCr 4:2:0 (N-C))
	[9]: 'YU12' (Planar YUV 4:2:0)
	[10]: 'YM24' (Planar YUV 4:4:4 (N-C))

But using GStreamer pipeline only NV12 and UYVY works, but cut image to 8-bit (Channel Y max 8 bit on both formats). My question is:

  1. There is the possibility to stream with GStreamer 10 bit gray images?
  2. Can I set two different formats on ISP selfpath and mainpath?
  3. Except BG10 and Y10 there is other 10bit format that I can use on GStremer in order to get RGA acceleration?
