Modify the scaler subdevice to accept setting the resolution of the source pad (previously the source resolution would always be 3 times the sink for both dimensions). Now any resolution can be set at src (even smaller ones) and the sink video will be scaled to match it. Test example: With the vimc module up (using the default vimc topology) media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]' media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]' media-ctl -d platform:vimc -V '"Scaler":0[fmt:RGB888_1X24/640x480]' media-ctl -d platform:vimc -V '"Scaler":0[crop:(100,50)/400x150]' media-ctl -d platform:vimc -V '"Scaler":1[fmt:RGB888_1X24/300x700]' v4l2-ctl -z platform:vimc -d "RGB/YUV Capture" -v width=300,height=700 v4l2-ctl -z platform:vimc -d "Raw Capture 0" -v pixelformat=BA81 v4l2-ctl --stream-mmap --stream-count=10 -z platform:vimc -d "RGB/YUV Capture" \ --stream-to=test.raw The result will be a cropped stream that can be checked with the command ffplay -loglevel warning -v info -f rawvideo -pixel_format rgb24 \ -video_size "300x700" test.raw Co-developed-by: Gabriela Bittencourt <gabrielabittencourt00@gmail.com> Signed-off-by: Gabriela Bittencourt <gabrielabittencourt00@gmail.com> Co-developed-by: Gabriel Francisco Mandaji <gfmandaji@gmail.com> Signed-off-by: Gabriel Francisco Mandaji <gfmandaji@gmail.com> Signed-off-by: Pedro Terra <pedro@terraco.de> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |
