I'd hope you can transparently replace v4l2src with libcamerasrc, the plugins currently lives inside the libcamera project. If not, I'd really like to know why. We can work together on adding missing controls (this is something I'm starting on soon). regards, Nicolas > > adam > > > > > <- "csis-32e40000.csi":1 [ENABLED] > > > pad1: Sink [fmt:unknown/0x0 field:none] > > > <- "rkisp1_params":0 [ENABLED,IMMUTABLE] > > > pad2: Source [fmt:YUYV8_2X8/640x480 field:none colorspace:raw xfer:none ycbcr:601 quantization:lim-range crop.bounds:(0,0)/640x480 crop:(0,0)/640x480] > > > -> "rkisp1_resizer_mainpath":0 [ENABLED] > > > pad3: Source [fmt:unknown/0x0 field:none] > > > -> "rkisp1_stats":0 [ENABLED,IMMUTABLE] > > > > > > - entity 6: rkisp1_resizer_mainpath (2 pads, 2 links) > > > type V4L2 subdev subtype Unknown flags 0 > > > device node name /dev/v4l-subdev1 > > > pad0: Sink [fmt:YUYV8_2X8/1920x1080 field:none colorspace:srgb xfer:srgb ycbcr:601 quantization:lim-range crop.bounds:(0,0)/1920x1080 crop:(0,0)/640x480] > > > <- "rkisp1_isp":2 [ENABLED] > > > pad1: Source [fmt:YUYV8_2X8/1920x1080 field:none colorspace:srgb xfer:srgb ycbcr:601 quantization:lim-range] > > > -> "rkisp1_mainpath":0 [ENABLED,IMMUTABLE] > > > > > > - entity 9: rkisp1_mainpath (1 pad, 1 link) > > > type Node subtype V4L flags 0 > > > device node name /dev/video0 > > > pad0: Sink > > > <- "rkisp1_resizer_mainpath":1 [ENABLED,IMMUTABLE] > > > > > > - entity 13: rkisp1_stats (1 pad, 1 link) > > > type Node subtype V4L flags 0 > > > device node name /dev/video1 > > > pad0: Sink > > > <- "rkisp1_isp":3 [ENABLED,IMMUTABLE] > > > > > > - entity 17: rkisp1_params (1 pad, 1 link) > > > type Node subtype V4L flags 0 > > > device node name /dev/video2 > > > pad0: Source > > > -> "rkisp1_isp":1 [ENABLED,IMMUTABLE] > > > > > > - entity 29: csis-32e40000.csi (2 pads, 2 links) > > > type V4L2 subdev subtype Unknown flags 0 > > > device node name /dev/v4l-subdev2 > > > pad0: Sink [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:srgb xfer:srgb ycbcr:601 quantization:full-range] > > > <- "imx219 1-0010":0 [ENABLED] > > > pad1: Source [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:srgb xfer:srgb ycbcr:601 quantization:full-range] > > > -> "rkisp1_isp":0 [ENABLED] > > > > > > - entity 34: imx219 1-0010 (1 pad, 1 link) > > > type V4L2 subdev subtype Sensor flags 0 > > > device node name /dev/v4l-subdev3 > > > pad0: Source [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:srgb xfer:srgb ycbcr:601 quantization:full-range crop.bounds:(8,8)/3280x2464 crop:(688,700)/1920x1080] > > > -> "csis-32e40000.csi":0 [ENABLED] > > > > > > It's at this point that everything except the ISP source is 1920x1080. > > > > > > When I try to set the ISP sink to 1080, it ends up being 640x480 and > > > the resizer sink is also changed to 640x480 > > > > > > root@beacon-imx8mp-kit:~# media-ctl -v -V "'rkisp1_isp':2 > > > [fmt:YUYV8_2X8/1920x1080 field:none]" > > > Opening media device /dev/media0 > > > Enumerating entities > > > looking up device: 81:3 > > > looking up device: 81:4 > > > looking up device: 81:0 > > > looking up device: 81:1 > > > looking up device: 81:2 > > > looking up device: 81:5 > > > looking up device: 81:6 > > > Found 7 entities > > > Enumerating pads and links > > > Setting up format YUYV8_2X8 1920x1080 on pad rkisp1_isp/2 > > > Format set: YUYV8_2X8 640x480 > > > Setting up format YUYV8_2X8 640x480 on pad rkisp1_resizer_mainpath/0 > > > Format set: YUYV8_2X8 640x480 > > > > > > > > > It's my understanding that the ISP should be able to handle 1920x1080, > > > and the resizer sink should match the ISP source. > > > > > > With the pipeline improperly setup, the capture fails. > > > > > > > .../bindings/media/rockchip-isp1.yaml | 79 ++++++++++- > > > > .../platform/rockchip/rkisp1/rkisp1-capture.c | 102 +++++++++++--- > > > > .../platform/rockchip/rkisp1/rkisp1-common.h | 32 +++++ > > > > .../platform/rockchip/rkisp1/rkisp1-debug.c | 14 +- > > > > .../platform/rockchip/rkisp1/rkisp1-dev.c | 67 +++++++-- > > > > .../platform/rockchip/rkisp1/rkisp1-isp.c | 128 +++++++++++++++++- > > > > .../platform/rockchip/rkisp1/rkisp1-regs.h | 90 ++++++++++++ > > > > .../platform/rockchip/rkisp1/rkisp1-resizer.c | 35 ++++- > > > > include/uapi/linux/rkisp1-config.h | 2 + > > > > 9 files changed, 509 insertions(+), 40 deletions(-) > > > > -- > > Regards, > > > > Laurent Pinchart
