16:44 <javierm> NishanthMenon: did you ever used the BeaglePlay with the RPi Camera rev 1.3 (OV5647 chip) ?

16:45 <NishanthMenon> https://git.beagleboard.org/beagleplay/beagleplay/-/blob/main/test-reports/dvt/test-procedure/test_camera.md?ref_type=heads

16:47 <NishanthMenon> Ov5640. Not 47. 5647 was raw sensor. The Bayer to yuv convertion needed CPU gst support. I think it came in later

16:49 <javierm> NishanthMenon: yeah, I also found https://forum.beagleboard.org/t/accessing-beagleplay-gpios-and-csi/34390/2ov and that's why I asked if also tested with OV5647

16:50 <javierm> I'm getting a ioctl(10, VIDIOC_STREAMON, [V4L2_BUF_TYPE_VIDEO_CAPTURE]) = -1 EPIPE (Broken pipe) due a mismatch between the camera source and csi2rx sink pad formats

16:50 <javierm> [ 46.146742] v4l2_subdev_link_validate_default: media bus code does not match (source 0x00003007, sink 0x0000200f)

16:50 <javierm> [ 46.157374] v4l2_subdev_link_validate_default: link was "ov5647 4-0036":0 -> "cdns_csi2rx.30101000.csi-bridge":0

16:52 <javierm> NishanthMenon: so isn't possible to use std gst elements like videoconvert and the TI gst elements must be used for bayer -> yuv conversion ?

17:02 <javierm> eballetbo: with media-ctl -V '"ov5647 4-0036":0[SRGGB10_1X10/640x480]' before the capture, the message goes away but I still get -EPIPE from VIDIOC_STREAMON, [V4L2_BUF_TYPE_VIDEO_CAPTURE]

17:02 <javierm> eballetbo: I'll continue digging tomorrow. Thanks for your help!

17:07 <NishanthMenon> jluthra: ^^ we discussed this a bit earlier..

20:45 <pivi> javierm: is the camera, e.g. MIPI-CSI, working with a mainline kernel? I have not tested this lately and I am interested in the topic ...

22:31 <javierm> pivi: I'm using latest mainline

22:32 <javierm> pivi: media-ctl -p shows me the media graph but as mentioned I coulnd't get a gst pipeline that works so far
