Hello, I'm trying to use a ov3640 camera sensor along with the isp of my overo board. I implemented the media-ctl pipeline configuration in my application, because I had trouble when trying to compile it on my board. Can someone help me out what I am doing wrong? the pipeline commands look like this: char test[] = "\"ov3640 3-003c\":0->\"OMAP3 ISP CCDC\":0[1], \"OMAP3 ISP CCDC\":1->\"OMAP3 ISP CCDC output\":0[1]"; char test2[] = "\"ov3640 3-003c\":0 [SGRBG10 2048x1536 (32,20)/2048x1536], \"OMAP3 ISP CCDC\":1 [SGRBG10 2048x1536]"; and my output log says: Opening media device /dev/media0 Enumerating entities Found 16 entities Enumerating pads and links Setting up link 16:0 -> 5:0 [1] Setting up link 5:1 -> 6:0 [1] Setting up selection target 0 rectangle (32,20)/2048x1536 on pad ov3640 3-003c/0 Selection rectangle set: (32,20)/2040x1536 Setting up format SGRBG10 2048x1536 on pad ov3640 3-003c/0 Format set: YUYV2X8 2040x1536 Setting up format YUYV2X8 2040x1536 on pad OMAP3 ISP CCDC/0 Format set: SGRBG10 2040x1536 Setting up format SGRBG10 2048x1536 on pad OMAP3 ISP CCDC/1 Format set: SGRBG10 2032x1536 it seems that it goes through without an error. so when I want to test the pipeline with yavta: ./yavta -f SGRBG10 -s 2048x1536 --capture=1 --file=image /dev/video2 I get this error log: root@overo2:~/yavta-HEAD-d9b7cfc# ./yavta -f SGRBG10 -s 2048x1536 --capture=1 --file=image /dev/video2 Device /dev/video2 opened.
